Description

FIELD OF THE INVENTION

The invention relates to the chemical industry, and in particular to deicing materials based on edible salt, calcined calcium chloride, corrosion inhibitors and can be used to obtain solid deicing materials with reduced corrosion activity.

The level of technology.

Most methods of dealing with winter slippery are aimed at removing the ice or snow layer from the road surface using chemical, mechanical, thermal and other methods, preventing the formation of a snow-ice layer or weakening its adhesion to the road surface.

To date, the most affordable deicing material (PGM) is sodium chloride / 1 /. Sodium chloride can reduce the temperature of ice formation on roads, as well as remove the formed ice, because the temperature of the eutectic of sodium chloride with ice is - 21.2 ° C / 2 /. However, sodium chloride is highly corrosive to metals and, in particular, to metallic structural materials of automobiles.

Famous PGM to prevent icing on the road, including a mixture of river sand and sodium chloride. Sodium chloride contained in such a sand-salt mixture is corrosive (Instructions for the protection of the environment in the construction of roads. BCN8-89 - Minavtodor, Moscow, 1989, p. 14). The method of application of this material refers to the combined, that is, the melting effect of the salt is complemented by the frictional property of sand.

Solid PGM is known, including a mixture of sodium chloride (sodium chloride) and calcium chloride (calcium chloride). The method of producing PGM is described in the source "ONE. Requirements for deicing materials. Rosavtodor of the Ministry of Transport of the Russian Federation, Moscow 2003 ”.

Due to the presence of calcium chloride in PGM, which generates heat during dissolution, a high melting rate of snow-ice deposits can be achieved, and the range of operating temperatures can be expanded up to -25 ° C. The high melting ability of a mixture of sodium and calcium chlorides causes a lower consumption of materials (reagents) in comparison, for example, with PGM based on only sodium chloride or a sand-salt mixture described above. Yielding to the melting ability of calcium chloride, its mixture with sodium chloride has a prolonged anti-icing effect. The duration of action of calcium chloride on the road surface in most cases does not exceed 3 hours. Sodium chloride, by contrast, acts on the pavement for up to 10 hours. The combination of sodium and calcium chlorides leads to a rational practical result.

The above-described PGM is also characterized by high corrosion activity with respect to metals. And in PGM there is no corrosion inhibitor (IR).

Increased modern requirements for the protection of road structures and cars from corrosion lead to the search for more effective technologies and means of combating snow and ice on all types of roads, including highways and city streets, as well as courtyards and sidewalks. Inorganic salts such as sodium, calcium, magnesium chlorides and metal corrosion inhibitors are widely used as such agents. Moreover, for the effective removal of ice, a high content of chlorides is required, and to weaken their corrosion activity, a high content of effective corrosion inhibitors is required. In modern PGM, the task of reducing corrosion activity is solved by reducing the deicing properties of materials and increasing the percentage of IR in PGM.

It will be shown below that in the invention, the task of reducing corrosion activity is achieved not by reducing chlorides in PHM, but by increasing the efficiency of IR.

Currently, in order to reduce the corrosive activity of PGM with respect to metals, they are introduced from fractions of percent to tens of percent of corrosion inhibitors. Currently, such corrosion inhibitors (or elements that are part of corrosion inhibitors) such as urea (NH ₂ ) ₂ CO, urotropin (CH ₂ ) ₆ N ₄ , 2-phosphonobutane-1,2,4-tricarboxylic acid tetrasodium acid have been widely used salt, sodium formate (sodium formate) HCO ₂ Na, potassium iron-hydrogen sulfide K ₃ [Fe (CN) ₆ ], sodium stearate NaC ₁₈ H ₃₅ O ₂ , potassium stearate KC ₁₈ H ₃₅ O ₂ , sodium nitrite NaNO ₂ , calcium nitrate Ca (NO ₃ ) ₂ and many others. Source / 3 / describes more than a thousand metal corrosion inhibitors.

An analogue to all variants of the invention is a method for producing PGM, described in RF patent 2285712, publ. 10/20/2006. In analogue, the problem of reducing the harmful corrosive effects of PGM is solved. This material is prepared by mixing sodium chloride, river sand, iron chloride and urea. Introduction to urea material in the amount of up to 4 wt. % allows to reduce the corrosive activity of PGM.

Signs that match the features of the invention: anti-icing material, urea, ... sodium chloride (which is part of the food table salt).

The disadvantage of the analogue is the relatively small decrease in the corrosivity of PGM.

Another analogue to all variants of the invention is a method for producing PGM described in RF patent 2521381, publ. 06/27/2014. The method involves mechanical mixing of the solid components of PGM: calcium chloride (calcium chloride), sodium chloride, ammonium chloride, sodium hydroxide and paraform. The analogue provides a decrease in the corrosive properties of PHM by using a corrosion inhibitor formed at the time of application of the composition.

Signs that match the features of the invention: a method for producing PGM, comprising mechanically mixing between themselves calcium chloride, sodium chloride (which is part of the food salt), ... corrosion inhibitor.

The disadvantage of the analogue is the relatively low efficiency of the corrosion inhibitor.

Also analogous to all variants of the invention is a method for producing anti-icing material described in RF patent 2259383, publ. August 27, 2005. In an analogue, calcium chloride (calcium chloride), sodium nitrite and urea are mixed. Urea (urea) and sodium nitrite are used as elements of a corrosion inhibitor. The content of calcium chloride in the solution depends on the ambient temperature for which it is designed.

Signs that match the features of the invention: a method of obtaining anti-icing material, mix calcium chloride, corrosion inhibitor, urea.

The disadvantage of the analogue is the relatively low efficiency of the corrosion inhibitor.

The prototype of all variants of the invention is a method for producing solid deicing material, including uniform mechanical mixing of crystalline food grade stone salt of the first grade, crystalline calcium chloride, technical calcined first grade, crystalline elements of a metal corrosion inhibitor, crystalline surfactant, crystalline acidity regulator (see http://newtechnolog.narod.ru/articles/52article.html).

These signs coincide with the signs of the restrictive parts of the claims of all variants of the invention.

As elements of IR in the prototype, disubstituted sodium phosphate and double superphosphate were used.

The disadvantage of the prototype is

The relatively low efficiency of the corrosion inhibitor in the composition of the solid anti-icing material obtained in the prototype is due to the fact that the elements of the corrosion inhibitor are not enriched with heavy isotopes of carbon ¹³ C and nitrogen ¹⁵ N.

The implementation of the invention.

In each embodiment of the invention, a method for producing solid PGM is contemplated. Solid PGM based on calcium and sodium chlorides have a high melting ability than liquid, due to the released heat of hydration of the salt, which is exhausted in liquid compositions during their manufacture (dissolution in water). The temperature of the solutions when mixing PGM with ice at negative temperatures is higher on solid materials than when using aqueous solutions having an ambient temperature.

The thermal effect due to the dissolution of calcium chloride (included in the PGM) is about - 21.75 kcal / mol, that is, it comes with the release of heat. The heat of dissolution of sodium chloride (included in PGM) has a positive value of +1.02 kcal / mol and, therefore, will come with a small heat consumption.

The freezing temperature of a 20% aqueous solution of CaCl ₂ - 18 ° C,

the freezing temperature of a 29.87% aqueous solution of CaCl ₂ - 55 ° C,

freezing temperature of a 30% aqueous solution of CaCl ₂ - 46 ° C

(http://www.angara.com.ua/22_teplonositeli.html).

the freezing temperature of a 23% aqueous NaCl solution is 21.1 ° C,

the freezing temperature of a 25% aqueous NaCl solution is 8.8 ° C

(http://www.angara.com.ua/22_teplonositeli.html).

With the combined use of NaCl and CaCl _{2, the} minimum freezing point is reached at 54.3% NaCl and 45.7% CaCl ₂ . In PGM obtained by the claimed methods, chlorides make up 94%, the remaining 6% - surfactants, IR and acidity regulator. Therefore, PGM obtained by the claimed methods 51% NaCl and 43% CaCl ₂ and 6% surfactant, IR and acidity regulator. For each PGM claimed in the invention, the freezing temperature of a 20% aqueous solution is 32 ° C. At the same time, the action of PGM on the road surface is 8-10 hours.

When implementing the methods claimed in the invention, deicing materials with reduced corrosion activity are obtained.

The ratio of the components of PGM is given in the section "Disclosure of the invention."

The above elements of the corrosion inhibitor are selected because when saturated with ¹³ C and ¹⁵ N isotopes, they significantly increase their effectiveness.

It should be noted that during the research, a number of elements of the corrosion inhibitor were revealed which, even with maximum saturation with ¹³ C and ¹⁵ N isotopes, they do not change their properties.

Before mixing the PGM components, a metal corrosion inhibitor is obtained.

A metal corrosion inhibitor is prepared as follows. Each of the above corrosion inhibitor elements is dissolved in distilled water so that the resulting aqueous solution contains one weight part of the corrosion inhibitor element and three weight parts of distilled water. Mixing is carried out at a positive temperature. Next, the resulting aqueous solution is subjected to cavitation treatment in a reactor installation.

The reactor facility used for the experiments was made using the materials given in the sources / 10-18 /.

Structurally, the reactor installation contains a tank 1 for the solution (see Fig. 1), a gear pump 5 with an electric drive (not shown in the figure), a cavitation reactor 8. In the reactor installation, the tank 1 is connected by a pipeline to the inlet to the pump 5, the outlet of the pump 5 is connected by a pipeline with the inlet of the cavitation reactor 8, the outlet of the cavitation reactor 8 is connected by a pipe 20 to the tank 1. At the inlet of the cavitation reactor 8 and the outlet of the cavitation reactor, manometers 9 and 6 are located to determine the pressure drop across the cavitation reactor. For technological needs, bypassing the cavitation reactor, a line 10 with a crane 7 is located. This line serves to bypass at least part of the solution bypassing the cavitation reactor when it is started and the regulations. A thermometer 2 and a heat exchanger 4 are located in the tank 1 for heating or cooling the solution 3. The device 4 comprises a heat exchanger located in the tank 1. If necessary, hot or cold water is passed through the heat exchanger, respectively, for heating or cooling the solution.

The cavitation reactor 8 is made as shown in FIG. 2, and contains a channel 23 for the movement of an aqueous solution. This channel, in the direction of movement of the aqueous solution (left to right in the figure), contains three constrictions 24, 25 and 26, before each narrowing of the channel there is a height-adjustable rod 27, 28 and 29. The rods turbulent the flow moving along the channel 23. Turbulization necessary to establish a cavitation mode at the lowest possible flow rates. If there were no rods, then the speed at which cavitation is established would increase by 15-17%.

As mentioned above, a height-adjustable rod is located before each narrowing of the channel. It is advisable that the rod 27 in front of the first, in the direction of movement of the solution constriction 24, is located at a distance equal to 2.1 diameters of the passage section at the point of restriction 24, the rod 28 in front of the second, in the direction of movement of the solution constriction 25, is located at a distance equal to 1.4 diameters of the passage section in the place of narrowing 25, the rod 29 before the third, in the direction of movement of the solution by narrowing 26, is located at a distance equal to 1.4 diameters of the bore at the point of narrowing 26.

Behind each narrowing in the cavitation reactor vessel there is a channel for supplying carbon dioxide or nitrogen to the cavitation region of the reactor. So, channel 30 is located behind narrowing 24, channel 31 is located behind narrowing 25, channel 32 is located behind narrowing 26.

In the course of testing the designs of the reactor installation and the cavitation reactor, and conducting experiments, recommendations were developed on the structural implementation of the elements of the installation and the cavitation reactor. So, the area of the passage section of the channel at the narrowing point is 8% of the maximum passage area of the channel. The maximum area of the passage section of the channel is equal to the area of the passage section of the pipeline located between the output of the gear pump and the inlet of the cavitation reactor. It is advisable that the area of the flow cross-sections of all pipelines and line 10 were the same. The shapes of the flow sections of the pipelines and the cavitation reactor can be any, it is convenient to carry them round. Although we conducted tests of cavitation reactors with rectangular shapes of passage sections of the channel, with oval shapes of passage sections, etc.

Each narrowing of the channel is made in the form of a nozzle (see Fig. 2) and has:

- the tapering part of the nozzle (in the direction of flow) is the part of the nozzle in front of the minimum flow area;

- minimum bore - section with a minimum bore;

- the expanding part of the nozzle is the part of the nozzle located behind the minimum flow area.

In the reactor installation used for the experiments, the shapes of the flow sections along the channel length of the cavitation reactor are made round, so the inner surfaces of the tapering and expanding parts are made in the form of a side surface of a truncated cone.

In the initial state, all valves 7, 48, 14, 49, 15, 50, 16 (see Fig. 1) of the reactor installation are closed.

For cavitation treatment, the resulting aqueous solution of the element of the corrosion inhibitor is poured into the tank 1 of the reactor installation. After which the solution 3, located in the tank 1, by means of the heat exchanger 4 is heated to 60 ° C. Then the solution 3 through the gear pump 5 is pumped from 170 to 720 times through the cavitation reactor. After the start of pumping, taps 14, 15 and 16 are opened. Carbon dioxide is supplied from the cylinders 17, 18 and 19 to the cavitation reactor. The gas supply is controlled on the basis of the readings of pressure gauges 9, 6, 11, 12 and 13 and is regulated using taps 14, 15 and 16.

The number of pumpings of solution 3 through a cavitation reactor 8 depends on the required content of heavy ¹³ C isotopes in the corrosion inhibitor element. Table 1.1 shows the dependence of the content of heavy carbon isotopes ¹³ C in the element of the corrosion inhibitor on the number of pumpings "n" of the aqueous solution of the element of the corrosion inhibitor through the cavitation reactor by means of a gear pump. The table shows that the more ¹³ C isotopes are required in the corrosion inhibitor element, the more times it is necessary to pump the solution through a cavitation reactor.

During cavitation processing, the height of each of the adjustable rods 27, 28 and 29 is set so that the rod covers 4-5% of the cross-sectional area of the channel at the location of the rod. During the operation of the installation, the rods interact with the flow, turbulence it, thereby ensuring the establishment of a cavitation mode at a minimum flow velocity in sections 14, 25 and 26.

In the process of cavitation treatment through the channel 30, located behind the first, by the movement of the solution by constriction, carbon dioxide is supplied from the cylinder 17 with the tap 14 open with a mass flow rate equal to 2% of the mass flow rate of the aqueous solution.

Through the channel 31, located behind the second, by the movement of the solution by constriction, carbon dioxide is supplied from the cylinder 18 with the open valve 15 with a mass flow rate equal to 1% of the mass flow rate of the aqueous solution.

Through the channel 32, located behind the third, by the movement of the solution by constriction, carbon dioxide is supplied from the cylinder 19 with the open valve 16 with a mass flow rate equal to 0.5% of the mass flow rate of the aqueous solution.

By means of a gear pump, the pressure drop across the cavitation reactor is maintained in the range from 7.5 ⁵ Pa to 8 · 10 ⁵ Pa, the temperature of the solution in the tank during cavitation treatment by means of the heat exchanger 4 is increased from 60 ° C to 75 ° C. Hot water is supplied through a heat exchanger, the temperature of which is controlled by thermometer 2.

In FIG. 3 shows a longitudinal section of a cavitation reactor 8. The direction of flow (movement of the solution) is indicated by arrow 33. Arrows 34, 35, 36, 37 show the movement of the stream along the channel of the cavitation reactor and behind the rods 27, 28, 29. The stream moving through the channel enters first narrowing. The cross-sectional area decreases, the flow rate increases. In the region of the minimum flow cross section 24, the flow rate increases so that the pressure in the flow becomes less than the saturated vapor pressure. The stream "boils" in this place - steam bubbles 38 are formed. Then the stream (liquid and steam bubbles) moving along the channel enters the expanding part, where the passage section of the channel increases and the speed decreases. The pressure in the stream becomes greater than the pressure of saturated steam, steam bubbles collapse. The collapse points of steam bubbles are shown at 39. Moreover, in the collapse region (in the region of the collapse point) of the cavitation bubble, an increase in pressure to several thousand atmospheres and an increase in temperature to a thousand or more degrees Celsius are observed.

The area in which bubbles form and collapse is called the cavitation area. As mentioned above, the rod 27 turbulizes the flow, and thereby facilitates the establishment of the cavitation flow regime at the lowest possible flow velocity.

Similarly, bubbles 40 arise and collapse 41 in the region of the passage section 25, and bubbles 42 and collapse 43 in the region of the passage section 26 are also formed.

Carbon dioxide is supplied through channels 30, 31 and 32 in the flow region behind the minimum flow sections 24, 25 and 26, saturated with steam bubbles. When steam bubbles collapse, a powerful dynamic effect on the environment surrounding the bubbles occurs. It is at the point of collapse that the element of the corrosion inhibitor is enriched with heavy carbon isotopes.

In FIG. 3, arrows 44 show the direction of gas movement through channels 30, 31, and 32.

During the cavitation treatment, the corrosion inhibitor element in solution is saturated with ¹³ C heavy carbon isotopes so that the ratio of ¹³ C carbon isotopes to the total carbon in the element is between 0.005 and 0.75. The control of the amount of carbon isotopes ¹³ C is carried out by high resolution mass spectroscopy. Samples for this are taken from tank 1. Gas entering the tank is removed from the tank through the neck 21. Removal of gas from the tank is shown by arrow 22.

Then close the taps 14, 15 and 16. The pump installation is turned off.

After that, the resulting aqueous solution of the above-mentioned element of the corrosion inhibitor is subjected to repeated cavitation treatment in the reactor installation, for which the aqueous solution located in the tank is heated by means of a heat exchanger to 80 ° C. The pump installation is turned on, valves 48, 49 and 50 are opened and the solution is pumped 50 to 390 times through a cavitation reactor 8 through a gear pump.

The number of pumpings of solution 3 through a cavitation reactor 8 depends on the required content of heavy isotopes ¹⁵ N in the element of the corrosion inhibitor.

Table 1.2 shows the dependence of the content of heavy nitrogen isotopes ¹⁵ N in the element of the corrosion inhibitor on the number of pumpings "n" of the aqueous solution of the element of the corrosion inhibitor through the cavitation reactor by means of a gear pump.

The table shows that the more ¹⁵ N isotopes are required in the corrosion inhibitor element, the more times it is necessary to pump the solution through a cavitation reactor.

In the process of repeated cavitation treatment, the height of each of the adjustable rods is set so that it covers 4-5% of the cross-sectional area of the channel at the installation site of the rod. In the particular case, the adjustment of the rods is left the same.

In the process of cavitation processing through the channel 30, located behind the first, by the movement of the solution by constriction, nitrogen gas is supplied from the cylinder 45 with the tap 48 open with a mass flow rate equal to 1% of the mass flow rate of the aqueous solution.

Through the channel 31, located behind the second, by the movement of the solution by constriction, gaseous nitrogen is supplied from the cylinder 46 with the open valve 49 with a mass flow rate equal to 0.5% of the mass flow rate of the aqueous solution.

Through the channel 32, located behind the third, by the movement of the solution by constriction, gaseous nitrogen is supplied from the cylinder 47 with the open valve 50 with a mass flow rate equal to 0.1% of the mass flow rate of the aqueous solution.

The gas supply is controlled based on the readings of pressure gauges 9, 6, 11, 12 and 13.

By means of gear pump 5, the pressure drop across the cavitation reactor is maintained in the range from 7.5 ⁵ Pa to 8 · 10 ⁵ Pa, the temperature of solution 3 in the tank 1 during the cavitation treatment by means of the heat exchanger 4 is increased from 80 ° C to 85 ° C.

As indicated earlier, Fig. 3 shows a longitudinal section of a cavitation reactor 8. The direction of flow (flow of the solution) is indicated by arrow 33. Arrows 34, 35, 36, 37 show the flow in the channel of the reactor and behind the rods 27, 28, 29. Flow moving along the channel gets into the first narrowing. The cross-sectional area decreases, the flow rate increases. In the region of the minimum flow cross section 24, the flow rate increases so that the pressure in the flow becomes less than the saturated vapor pressure. The flow in this place “boils” - steam bubbles 38 are formed. Further, the flow (liquid and steam bubbles) moving along the channel enters the expanding part, where the passage section of the channel increases and the speed decreases. The pressure in the stream becomes greater than the pressure of saturated steam, the vapor bubbles collapse 39. At the same time, in the area (in the place) of the collapse of the cavitation bubble, an increase in pressure to several thousand atmospheres and an increase in temperature to a thousand or more degrees Celsius are observed.

The area in which bubbles form and collapse is called the cavitation area. As mentioned above, the rod 27 turbulizes the flow, and thereby facilitates the establishment of the cavitation flow regime at the lowest possible flow velocity.

Similarly, bubbles 40 arise and collapse 41 in the region of the passage section 25, and bubbles 42 and collapse 43 in the region of the passage section 26 are also formed.

Nitrogen gas is supplied through channels 30, 31, and 32 in the flow region saturated with vapor bubbles, for minimum passage sections 24, 25, and 26. When the vapor bubbles collapse, a powerful dynamic effect on the environment surrounding the bubbles occurs. It is at the point of collapse that the element of the corrosion inhibitor is enriched with heavy nitrogen isotopes.

During the cavitation treatment, the corrosion inhibitor element in solution is saturated with heavy nitrogen isotopes ¹⁵ N so that the ratio of the number of nitrogen isotopes ¹⁵ N to the total amount of nitrogen in the element is from 0.0001 to 0.1375. Control of the amount of nitrogen isotopes ¹⁵ N perform mass spectroscopy High resolution. Samples for this are taken from tank 1. Gas entering the tank is removed from the tank through the neck 21. Removal of gas from the tank is shown by arrow 22.

Next, the valves 48, 49 and 50 are closed. The installation is turned off.

After repeated cavitation treatment of the solution, crystallization of this element of the corrosion inhibitor is carried out, for which the solution is poured from the tank 1 into a device for evaporating water. 95.5% of water is evaporated from the aqueous solution. Crystallization is carried out by evaporation.

After cavitation treatment and crystallization of all the above elements of the corrosion inhibitor, they are mixed with the remaining components of the anti-icing material in the percentage indicated in the section “Disclosure of the invention”.

The cavitation treatment of the elements of the corrosion inhibitor is carried out in such a way that the percentage of carbon isotopes ¹³ C in each element of the corrosion inhibitor is the same and the percentage of nitrogen isotopes ¹⁵ N in each element of the corrosion inhibitor is the same.

The processes of cavitation treatment and crystallization of the elements of the corrosion inhibitor, as well as mixing the crystalline components of the PGM for all variants of the invention are identical.

Crane 7 and highway 10 are used for technological purposes. The reactor installation is flushed with water with open valve 7, and closed valves 48, 14, 49, 15, 50 and 16. Line 10 with open valve 7 can be used to mix the corrosion inhibitor element with water.

The appearance of the reactor installation is shown in the photograph (see Fig. 4).

An example of calculating the cavitation treatment time is given below.

During cavitation treatment, the solution is pumped n times through a cavitation reactor using a gear pump, while the operating time t of the reactor installation is determined by the formula:

t = nV / Q,

where n is the number of pumpings of an aqueous solution through a cavitation reactor by means of a gear pump;

V is the volume occupied by the solution in the tank;

Q is the volumetric flow rate of the gear pump.

In the experimental reactor installation, a gear pump NMSh 5-25-4.0 / 10 was used. At a pump with a gear speed of 1450 rpm, the flow rate Q = 4 m ³ / h.

The pressure is provided equal to 10 · 10 ⁵ Pa, and the power consumption is 1.8 kW.

The pump is driven by an asynchronous electric motor AIR100S4UZ.

The volume of the tank is 0.01 m ³ , the volume occupied by the solution is 0.008 m ³ .

We give an example of calculating the operating time of a reactor installation.

170 pumping a solution through a cavitation reactor will require 0.34 hours (or 1224 seconds).

Another example, 400 pumping a solution through a cavitation reactor will require 0.8 hours (or 2880 seconds).

And 1110 pumping (this is the maximum number of pumping provided for the implementation of the invention) through a cavitation reactor will require 2.22 hours (or 7992 seconds).

In the sources / 11-18 / a reactor installation for the isotope enrichment of drugs is described. At the beginning of the experimental work, this setup was used for cavitation treatment of corrosion inhibitor elements. However, the large energy and time costs involved in the processing of solutions required the development and manufacture of a new reactor installation (see Fig. 1-4).

The old reactor installation / 11-18 / has a power consumption of 75 kW; it uses a 6NK-6X1 centrifugal pump with a flow rate of 90 m ³ / h and a feed of 125 m, as well as an 18 liter solution tank (of which 16 liters are for solution )

The new reactor installation used to implement all variants of the invention has a power consumption of 1.8 kW. A NMSh 5-25-4.0 / 10 gear pump was used in the installation, with a flow rate of 4 m ³ / h, a feed of 100 m, a capacity for a solution of 10 liters (of which 8 liters for a solution).

In the new installation, compared with the old installation described in the sources / 10-18 /, the power consumption of the pump is reduced by more than 40 times, the flow rate is reduced by 22 times.

When working on an old installation, the saturation of the corrosion inhibitor element with ¹³ C isotopes to a content of 75% was carried out for several days (up to 65 hours). For working with medicines, such costs are acceptable, but for working with PGM, the costs are excessive. Therefore, a new reactor installation was developed and experimentally tested.

When working on a new installation, the corrosion inhibitor element was saturated with ¹³ C isotopes to a content of 75% and ¹⁵ N isotopes up to 13.75% for 2.22 hours (with a solution volume of 8 liters). Another 8 liters was also processed for 2.22 hours. Thus, in a new installation for processing 16 liters of solution, 4.44 hours will be required (with a power consumption of 1.8 kW). In this case, 8 kW · hour of electricity will be consumed.

On an old installation, the processing time of 16 liters was 65 hours with a power consumption of 75 kW. Energy costs will amount to 4800 kW · hour of electricity.

Energy saving - up to 600 times, time saving - up to 14 times. This is a significant saving in energy and uptime.

It is stated design of the reactor plant and cavitation reactor provides effective corrosion inhibitor enrichment of heavy carbon isotopes ¹³ C and ¹⁵ N. The nitrogen now more effective systems for these purposes no.

As mentioned above, each of the above-described variants of the invention is aimed at achieving a technical result consisting in increasing the effectiveness of a corrosion inhibitor in the composition of the obtained solid anti-icing material by enriching the corrosion inhibitor with heavy isotopes of carbon ¹³ C and nitrogen ¹⁵ N in a cavitation reactor of a new design.

When developing an application for an invention, it was experimentally proved that to increase the effectiveness of a corrosion inhibitor in the composition of the obtained solid deicing material, it is required that the ratio of the number of carbon isotopes ¹³ C to the total amount of carbon in the element of the corrosion inhibitor be from 0.005 to 0.75 (from 0.5% to 75%), as well as the ratio of the amount of nitrogen isotopes ¹⁵ N to the total amount of nitrogen in the element of the corrosion inhibitor, ranged from 0.0001 to 0.1375 (from 0.01% to 13.75%).

It was proved that a lower content of carbon isotopes ¹³ C and nitrogen isotopes ¹⁵ N (below the left border of the range) does not lead to the achievement of a technical result. A higher content of the above isotopes (above the right border of the range) does not lead to an increase in efficiency, but leads only to an increase in the cost of the corrosion inhibitor and, in general, PGM.

Experimental studies of the corrosive activity of PGM were carried out in 3 stages.

Stage 1. Conducting studies with PGM obtained by methods 1-5 (see the claims), without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N.

2 stage. Conducting studies with PGM obtained by methods 1-5 (see the claims), with saturation of corrosion inhibitors only with heavy isotopes ¹³ C or only heavy isotopes ¹⁵ N.

3 stage. Conducting studies with PGM obtained by methods 1-5 (see the claims), with saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N.

Stage 1.

Conducting studies with PGM obtained by methods 1-5 (see paragraphs 1-5 of the claims), without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N.

PGM was prepared by the methods described in paragraphs 1-5 of the claims, but without saturation of the corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N. The components of the PGM were only mechanically mixed.

Tables 2-4 present experimental data on the corrosion activity of St3ps steel on solutions of anti-icing materials ( ¹³ C and ¹⁵ N isotopes are absent). These solutions in the tables are called basic anti-icing materials. In table 2, a 5% solution of basic PGM is considered, in table 3, a 10% solution of PGM is considered, in table 4, a 20% solution of PGM is considered.

In tables 2-4 in the left column (in the first column) are the serial numbers of deicing materials. Number 1 corresponds to PGM obtained by the method described in paragraph 1 of the claims (without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N). Number 2 corresponds to PGM obtained by the method described in paragraph 2 of the claims (without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N). Number 3 corresponds to PGM obtained by the method described in paragraph 3 of the claims (without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N). Number 4 corresponds to PGM obtained by the method described in paragraph 4 of the claims (without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N). Number 5 corresponds to PGM obtained by the method described in paragraph 5 of the claims (without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N).

The St3ps steel (GOST14637) used in the experiments contained: carbon - 0.20%, silicon - 0.08%, manganese - 0.45%, nickel, copper, chromium - up to 0.3%, arsenic up to 0.05%, sulfur up to 0.05, phosphorus up to 0.04%, respectively. From sheet steel 4 mm thick, plates 20 × 30 mmm in size were cut. Experimental studies of PGM with corrosion inhibitors were carried out according to GOST 9.514-99. The corrosion rate was determined by the polarization resistance device P5126. In the device, the measured value of the polarization resistance was automatically converted to the corrosion rate in mm / year.

Analysis of tables 2, 3 and 4 shows that the corrosion rate decreases with decreasing solution temperature.

A comparative analysis of tables 2, 3 and 4 also shows that with an increase in the PGM content in the solution, the corrosion rate increases.

2 stage.

Conducting studies with PGM obtained by methods 1-5 (see paragraphs 1-5 of the claims), with saturation of corrosion inhibitors only with heavy isotopes ¹³ C.

PGM was prepared by the methods described in paragraphs 1 to 5 of the claims, but without saturation of corrosion inhibitors with heavy isotopes of ¹⁵ N. In each method, corrosion inhibitors were saturated only with heavy isotopes of ¹³ C.

Table 6 presents the data on the corrosion activity on St3ps steel of deicing materials obtained by the methods described in paragraphs 1-5 of the claims. The composition of PGM includes a corrosion inhibitor containing from 0.4% to 80% of carbon isotopes ¹³ C.

The temperature of anti-icing materials is -5 ° C. A 5% PGM solution in distilled water was used in the experiments.

The table shows that when the content of ¹³ C carbon isotopes in corrosion inhibitors is 0.4%, the corrosive activity of PGM with serial numbers 1, 2, 3, 4 and 5 is almost equal to the corrosivity of PGM described in table 2 (column No. 2 at temperature anti-icing materials -5 ° C). This means that an increase in the content of ¹³ С carbon isotopes in the corrosion inhibitor to a value of 0.4% does not lead to a decrease in the corrosivity of PHM.

But when the content of ¹³ C carbon isotopes in IR is 0.5%, the corrosive activity of PHM with serial numbers 1, 2, 3, 4 and 5 becomes less than the corrosivity of PHM described in table 2 (column No. 2 at anti-icing materials -5 ° C). It can be seen that the corrosion rate is lower. This means that an increase in the content of ¹³ C in IR carbon to a value of 0.5% leads to a decrease in the corrosivity of PHM by about 15%.

With a further increase in the ¹³ C carbon isotope content in IR, the corrosive activity of PGM decreases. Moreover, when the content of ¹³ C carbon isotopes in the IR is 75%, the minimum corrosion rate is achieved. With a further increase in the content of ¹³ C carbon isotopes in IR, the corrosion rate no longer decreases, but the energy and time costs for manufacturing IR increase.

A comparative analysis of the corrosivity of PGM with corrosion inhibitors not containing carbon isotopes of ¹³ C and nitrogen ¹⁵ N with the corrosion activity of PGM with corrosion inhibitors enriched only with carbon isotopes of ¹³ C (when the content of ¹³ C isotopes is 75%) showed that a decrease in the corrosion rate can reach 70%.

It can be seen that the results are almost identical (the difference in values does not exceed 0.003). This means that an increase in the content of ¹³ C in the corrosion inhibitor to 0.4% does not lead to a decrease in the corrosivity of PGM.

But when the content of ¹³ C carbon isotopes in IR is 0.5%, the corrosive activity of PHM with serial numbers 1, 2, 3, 4 and 5 becomes less than the corrosivity of PHM described in table 3 (column No. 2 at anti-icing materials -5 ° C). It can be seen that the corrosion rate is lower. This means that an increase in the content of ¹³ С in IR carbon to a value of 0.5% leads to a decrease in the corrosivity of PHM by approximately 16%.

With a further increase in the ¹³ C carbon isotope content in IR, the corrosive activity of PGM decreases. Moreover, when the content of ¹³ C carbon isotopes in the IR is 75%, the minimum corrosion rate is achieved. With a further increase in the content of ¹³ C carbon isotopes in IR, the corrosion rate no longer decreases, but the energy and time costs for manufacturing IR increase.

It can be seen that the results are almost identical (the difference in values does not exceed 0.003). This means that an increase in the content of ¹³ C in the corrosion inhibitor to 0.4% does not lead to a decrease in the corrosivity of PGM.

But when the content of ¹³ C carbon isotopes in IR is 0.5%, the corrosive activity of PHM with serial numbers 1, 2, 3, 4, and 5 becomes less than the corrosivity of PHM described in table 4 (column No. 2 at anti-icing materials -5 ° C). It can be seen that the corrosion rate is lower. This means that an increase in the content of ¹³ С in IR carbon to a value of 0.5% leads to a decrease in the corrosivity of PHM by approximately 16%.

Moreover, when the content of ¹³ C carbon isotopes in the IR is 75%, the minimum corrosion rate is achieved. With a further increase in the content of ¹³ C carbon isotopes in IR, the corrosion rate no longer decreases, but the energy and time costs for manufacturing IR increase.

As mentioned earlier, an increase in the content of ¹⁵ N nitrogen isotopes in IR from 13.75% to 14% practically does not lead to a further decrease in corrosion activity. This is experimentally confirmed. Tables 60-68 show the data on the corrosion activity of St3ps steel anti-icing materials obtained by the methods described in paragraphs 1-5 of the claims. PGM includes a corrosion inhibitor containing 14% of nitrogen isotopes ¹⁵ N of the total amount of nitrogen in IR and carbon isotopes ¹³ C from 0.4% to 80% of the total carbon content in IR. The data in the tables practically coincide with the data in tables 51-59.

A joint analysis of tables 2-68 shows that it is advisable to produce PHM by the methods described in paragraphs 1-5 of the claims in such a way that the corrosion inhibitors included in the PHM contain ¹³ C carbon isotopes and ¹⁵ N nitrogen isotopes, and the ratio of the number of carbon isotopes ¹³ С to the total amount of carbon in the IR element should be from 0.005 to 0.75 (from 0.5% to 75%) and the ratio of the number of nitrogen isotopes ¹⁵ N to the total amount of nitrogen in the IR element should be from 0.0001 to 0.1375 ( from 0.01 to 13.75%).

Above, experimental studies of the corrosive activity of PGM, obtained by the claimed methods, on St3ps steel are described. It has been experimentally established that the corrosive activity of PGM obtained by the claimed methods (for any content of ¹³ C and ¹⁵ N isotopes in IR) is lower for St45 steel than for St3ps steel by about 2-2.5 times. And the corrosive activity of PGM obtained by the claimed methods (for any content of ¹³ C and ¹⁵ N isotopes in IR) is lower for St60 steel than for St3ps steel by about 1.9-2 times. The corrosive activity of PGM obtained by the claimed methods was tested on other materials and alloys. In all cases, the introduction of ¹³ C and ¹⁵ N isotopes into IR, which is part of the PHM, leads to a significant decrease in the corrosivity of the PHM.

When developing an application for an invention, assessments were made of the melting ability of PGM obtained by methods 1-5 (see the claims) for loose snow, rolling and ice. Also, estimates were made of the melting ability of basic PGM obtained by methods 1-5 (see the claims) on snow, coast and ice without saturation of corrosion inhibitors with heavy isotopes ¹³ C and ¹⁵ N.

Table 5 presents the dependence of the melting ability of the five basic PGM on snow and coast from the temperature of the outside air. The floating ability of the base PGM is measured in "g / g" (shows how many grams of loose snow or runoff can melt 1 gram PGM). For ice, the melting capacity values given in Table 5 should be reduced by five times. The table shows that with a decrease in the temperature of snow or coast, the melting ability of PGM decreases.

Deicing materials obtained for studies of corrosion activity were used to assess the melting ability of PGM. It turned out that saturation of corrosion inhibitors with heavy ¹³ C and ¹⁵ N isotopes has practically no effect on the ability of PGM to melt snow, ice and ice. Thus, the data shown in table 5 can be attributed to PGM obtained by methods 1-5 (see the claims).

In practice, to combat slippage, PGM obtained by any of the methods claimed in the invention is applied to snow, rolling or ice located on the road, mechanically or manually. To determine the weight of the PGM necessary to combat, for example, with the run on the road, determine the thickness of the run on the road, then determine the weight of the run on 1 m ^{2 of the} road, then the obtained weight (in grams) of the run is divided by the value of the melting ability from table 5 and get the result is how much PGM is needed in grams to process 1 m ^{2 of the} road to completely melt the run.

Moreover, for all variants of the invention, the achievement of the technical result is achieved, which consists in increasing the effectiveness of the corrosion inhibitor in the composition of the obtained anti-icing material due to the effective enrichment of the corrosion inhibitor with heavy isotopes of carbon ¹³ C and nitrogen ¹⁵ N in a reactor installation with a cavitation reactor, without compromising the anti-icing properties of PGM .

Also, when developing an application for an invention, experiments were conducted to assess the impact of PGM obtained by the claimed methods on plant life. The negative effect of PGM on the vital activity of a plant consists of the negative effects of chlorides, a corrosion inhibitor, a surfactant, and an acidity regulator on plants. The experiments compared the effect on the vital activity of PGM plants containing IR with isotopes of carbon ¹³ C and nitrogen ¹⁵ N with the effect on the vital activity of PGM plants containing IR without isotopes of carbon ¹³ C and nitrogen ¹⁵ N.

Three beds were prepared for research, on which seeds of Butterhead lettuce, First Class and Alphabet pickles, grasses for roadside lawns were planted (Road mix containing annual ryegrass - 20%, plantain - 15%, timothy meadow - 35%, hedgehog team - 30%).

The first garden was watered with water for irrigation from an open source.

The second garden was watered with a 5% solution of PGM (with IR without carbon isotopes ¹³ C and nitrogen ¹⁵ N) with water for irrigation from an open source.

The third garden was divided into 3 parts.

The first part of the third garden was watered with a 5% solution of PHM (with IR containing 0.5% carbon isotopes ¹³ C and 0.01% nitrogen ¹⁵ N) with water for irrigation from an open source.

The second part of the third garden was watered with a 5% solution of PGM (with IR containing 15% of carbon isotopes ¹³ C and 3% nitrogen ¹⁵ N) with water for irrigation from an open source.

The third part of the third garden was watered with a 5% solution of PGM (with IR containing 75% of carbon isotopes ¹³ C and 13.75% nitrogen ¹⁵ N) with water for irrigation from an open source.

Seed germination and plant growth was observed for 4 weeks from 05/12/2014 to 06/13/2014. Place of experiments - Moscow region.

After 4 weeks of observation, there was practically no difference in the germination and growth of plants in the first and second beds. There was no difference in the germination and growth of plants in the second garden and the first part of the third garden.

The difference in the germination and growth of plants in the second garden and the second part of the third garden was noticed. In the second part of the third garden, seedlings were observed 2 days earlier than the seedlings in the second garden. Subsequently, the growth and appearance of plants on the second bed and the second part of the third bed did not practically differ.

The difference in the germination and growth of plants in the second bed and the third part of the third bed was also noticed. In the third part of the third bed, seedlings were observed 3 days earlier than seedlings in the second bed. Subsequently, in the third part of the third garden, more intensive plant growth was observed than the growth of plants in the second garden. By the end of the observation period, the dynamics of plant growth in the third part of the third bed and the growth dynamics of plants in the second bed were leveled.

This allowed us to conclude that the presence of a corrosion inhibitor with carbon isotopes ¹³ C and nitrogen ¹⁵ N in PGM does not adversely affect plants.

In addition, comparative tests were carried out on watering plants of 10% aqueous solutions of PHM with carbon isotopes ¹³ C and nitrogen ¹⁵ N and without carbon isotopes ¹³ C and nitrogen ¹⁵ N. There was no difference in germination and growth of plants.
