METHOD AND DEVICE FOR RESONANT EXCITATION OF LIQUIDS AND
METHOD AND PLANT FOR FRACTIONATION OF HYDROCARBON LIQUIDS
THE FIELD OF THE INVENTION
The invention relates to the technology of processing of liquids, having in their composition bonded hydrogen, and is directly concerned with a method and a device for resonant excitation of liquids and a method and a plant for fractionation of hydrocarbon liquids.
The practical field of the industrial application of the invention covers the oil refining, chemical and other branches of industry, associated with technological processing of liquids, having in their composition bonded hydrogen, primarily of hydrocarbon liquids, such as gas distillate, crude oil, intermediate products and products of oil refining, etc.
DESCRIPTION OF THE PRIOR ART
From the state of the art the methods of acoustic excitation of liquids are generally known for solving of various technological problems. These methods comprise the transfer of oscillatory energy to the liquid with the help of a source of mechanical oscillations placed into the liquid, in whose capacity can be used widely known in the technology mechanical, electromechanical, magnetostrictive, piezoelectric, hydrodynamic and other acoustic emitters.
In particular, from the International Application PCT1RU92100195 the rotary-type hydrodynamic acoustic emitter (ultrasonic activator) is known, which can be used in the process of preliminary treatment of liquids for destructive transformation of their chemical bonds at the molecular level.
These known methods and means of acoustic excitation of liquids, as applied to destructive transformation of their chemical bonds, possess a common disadvantage, consisting in that they do not provide criteria for the selection of definite resonant frequencies, which fact can sharply reduce the efficiency of the preliminary acoustic treatment of liquids.
From the International Application PCT/RU92/00194 the method and device are also known for preliminary treatment and fractionation of hydrocarbon liquids with the help of the rotary-type hydrodynamic acoustic emitter. The method of the preliminary treatment of liquids comprises consecutive supply of liquid into the cavities of several blade-type working wheels, discharge of liquid from the cavity of each working wheel into the cavity of the stator through the outlet openings of the working wheels and straight-through openings of the stator. In this case the peripheral surface of the working wheels has the minimum clearance with respect to the stator. The flows of liquid running out of the outlet openings of the working wheels undergo sharp periodical interruptions, which induce mechanical oscillations of audio frequency in the liquid. The device for preliminary treatment of liquids comprises the rotor, including the shaft resting on bearings and several blade-type working wheels installed on the shaft. Each of them is made as a disc with the peripheral annular wall, in which a series of outlet openings evenly spaced along the circumference, is made for liquid. The device comprises the stator, having intake and discharge openings for liquid and coaxial walls, bearing against the annular peripheral wall of each working wheel with the minimum technically attained clearance, at that a series of straight-through openings for liquid being made in each of the coaxial walls. The device for fractionation of hydrocarbon liquids is ganged up with the device for preliminary treatment of liquids and comprises the chamber conjugated with the last working wheel for separation of the treated liquid into the liquid and vaporous phases, and the chamber for condensation of the vaporous phase, communicating with the former chamber.
The described method and device for preliminary treatment of hydrocarbon liquids do not allow, however, the potentialities of such treatment to be realized to the maximum extent for more efficient fractionation of the treated liquid, since here the selection of the optimum relationship between decisive working parameters, such as the radius of the peripheral surface of the working wheel and the rotation frequency thereof is left without attention.
From the International Application PCT/RU95/00071 there are also known the method and device for conditioning of hydrocarbon liquids with the help of the rotary-type hydro-dynamic source of mechanical oscillations. The method includes the supply of liquid into the cavity of the working wheel rotating inside the stator, the discharge of liquid from the cavity of the working wheel through a series of outlet openings, evenly spaced along the circumference, into the annular chamber, limited by the peripheral surface of the working wheel and the inner coaxial surface of the stator, and the discharge of liquid from the annular chamber. The discharge of liquid from the annular chamber is effected preferably into the collecting chamber of the stator through a series of straight-through openings, evenly spaced along the inner coaxial surface of the stator, the openings being consecutively arranged opposite to the outlet openings of the working wheel during rotation thereof. In this case the nominal value of the radius R of the peripheral surface of the working wheel and the nominal rotation frequency n thereof are preset depending on the selected quantity K of the outlet openings thereof according to the following empirical relationships:

Such methods and plants for fractionation of hydrocarbon liquids with the use of the pre-installed rotary hydrodynamic device for their preliminary treatment make it possible to increase the yield of the most valuable light fractions. However, in practice the potentialities of such technology fail to be realized to the maximum extent. The reason for this seems to be responsible both inadequate efficiency of the inherent rotary hydrodynamic device for preliminary treatment of liquid, and insufficiently rational building-in of this device into traditional schemes of plants for fractionation of hydrocarbon liquids.
THE OBJECT AND ESSENCE OF THE INVENTION
The purpose of this invention is to provide such a method and a device for resonant excitation of liquids, having in their composition chemically bonded hydrogen, primarily of hydrogen liquids, as well as such a method and a plant for their fractionation, which make it possible to increase the efficiency of preliminary treatment of liquid to the maximum, thus respectively to influence positively the efficiency of subsequent fractionation in respect of the maximum increase of the yield of the most valuable light fractions.
The stated problem is solved by that in the proposed method of resonant excitation of liquids, having in their composition bonded hydrogen, which as the known methods is effected by means of oscillatory influence on liquid for destructive transformation of the chemical bonds thereof at the molecular level and includes the transfer of oscillatory energy to liquid with the help of a source of mechanical oscillations placed into the liquid, according to the principal embodiment of the method, resonant excitation of liquid is executed on one of the basic frequencies obeying the common relationship F = F, N-1/2, where (1) N >_1 - the selected integer, F, = 63.992420 [kHz] - the basic oscillation frequency at N = 1.
In the described method of resonant excitation, as applied to hydrocarbon liquids, executed along with the known methods, with the help of the rotary hydrodynamic source of mechanical oscillations and including the supply of the liquid being treated into the cavity of the working wheel, rotating inside the stator, the discharge of liquid from the cavity of the working wheel through a series of outlet openings, evenly spaced along the peripheral surface thereof, into the annular chamber, limited by the peripheral surface of the working wheel and inner coaxial surface of the stator, and the outflow of liquid from the annular chamber, according to a particular case of embodiment of the method, resonant excitation of liquid is effected abiding by relationship n R = 1.16141 F, where (2) n[1/s] - the rotation frequency of the working wheel, R [m] - the radius of the peripheral surface of the working wheel.
At such relationship of said parameters there is achieved, as has been confirmed experimentally, the efficient resonant treatment of hydrocarbon liquids effecting such destructive transformation of the chemical bonds of liquid at the molecular level and respectively such influence on its physical-chemical properties, which during subsequent fractionation predetermines a substantial increase of the yield of highly valuable light fractions.
This effect can be explained by the influence of oscillatory excitation of liquid in the resonant duty daring simultaneous circular movement thereof at the definite velocity along the corresponding definite radius.
At the definite value of the radius R of the working wheel and actual rotation frequency thereof n N = 3.8395452 (N 7)- 312 =106 (approximately 10% for N=
100...200) there is further sufficient increase of the efficiency of resonant treatment of liquid, as compared with the level, characteristic of the above-described analogs. However, in the preferred embodiment of the method it is advantageous to maintain the calculated rotation frequency of the working wheel with a deviation of 1%, thus achieving the most efficient resonant treatment of liquid.
The posed problem is simultaneously solved with the help of a proposed device for resonant treatment of hydrocarbon liquids, which makes it possible to realize the above-described method of resonant treatment of hydrocarbon liquids in the scope of the unified inventive concept. This device, as the known ones, comprises = a rotor including a shaft resting on bearings and at least one working wheel installed on the shaft, at that = the working wheel is made as a disc with a peripheral annular wall, wherein a series of outlet openings, evenly spaced along the circumference, is made for liquid, = a stator having a wall coaxial to the working wheel, an intake opening for the supply of liquid, communicating with the working wheel cavity, and a discharge opening for liquid outflow, = an annular chamber formed by the coaxial wall of the stator and peripheral annular wall of the working wheel and communicated with the stator discharge opening, and = a means for driving the rotor at the preset rotation frequency.
According to the principal embodiment of the device, the value of the external radius of the peripheral annular wall of the working wheel constitutes R = 2.8477729 n-2f3=104 [mm], where (3) n 14.651908 F 3[r.p.m.] - the rotation frequency of the working wheel, F 63.992420 N-1/2 [kHz] - the basic frequency of resonant excitation, N _1 - the selected integer, while the value of the internal radius of the stator coaxial wall constitutes R,= R + B S (2 7r)-i [mm], where (4) B >_1 - the selected integer, S = 7.2973531 [mm] - the pitch of outlet openings of the working wheel along the circumference of the radius R.
According to preferred, embodiment of the device, it is advantageous to select the radial extent of the working wheel outlet openings multiple or more preferably equal to value S(2-x)l.
According to the most preferred embodiment of the device the means for driving the rotor comprises a system for controlling the rotation frequency thereof with a deviation of 1%
from its calculated value.
The posed problem is simultaneously solved with the help of a proposed method of fractionation of hydrocarbon liquids, which makes it possible to realize the above-described method of resonant treatment of hydrocarbon liquids in the scope of the unified inventive concept. This method, as the known ones, is executed by way of distillation and includes preliminary treatment of liquid with the help of a pre-installed rotary hydrodynamic source of mechanical oscillations, the supply of preliminary treated liquid into the fractionating tower and the discharge of distilled fractions and residual fraction. According to the principal embodiment of the method of fractionation, liquid is preliminarily treated by resonant excitation thereof in compliance with the above-described proposed method of resonant excitation of hydrocarbon liquids.
According to the preferred embodiment of the method of fractionation, from the general flow of liquid to be fractionated a partial flow is diverted and subjected to said preliminary treatment, whereupon both flows are combined before feeding into the rectification tower.
According to the more preferred embodiment, the partial flow amounts to 5...80 l0, the most preferred being 20...50% from the full flow.
It has been experimentally established that preliminary treatment by the proposed method of less than 5% from the full liquid flow fails as yet to achieve appreciable efficiency of resonant excitation, while preliminary treatment of more than 80% from the full liquid flow does not any longer give a substantial increase of the efficiency of such treatment.
In the most preferred embodiment of the method of fractionation, comprising, along with the known methods, a partial return into the fractionating tower of its own residual fraction, the returned residual fraction is subjected to preliminary treatment by way of resonant excitation, thus achieving the most efficient fractionation.
The stated problem is simultaneously solved with the aid of a proposed plant for fractionation of hydrocarbon liquids, which makes it possible to realize the above-described method of fractionation of hydrocarbon liquids in the scope of the unified inventive concept.
This plant, as the known ones, comprises a feeding pump, at least one fractionating tower and a pre-installed rotary hydrodynamic device for preliminary treatment of liquid, all interconnected by pipelines. According to the principal embodiment of the plant, the device for preliminary treatment of liquid is made as the above-described proposed device for resonant excitation of hydrocarbon liquids and is sequentially installed between the feeding pump outlet and the fractionating tower inlet.
According to the preferred embodiment, the inlet of the device for resonant excitation of liquid is connected to the inlet of the fractionating tower through a shut-off-control element.
According to the more preferred embodiment, the outlet of the device for resonant excitation of liquid is connected to the inlet of the fractionating tower through a shut-off-control element. The possibility of resonant treatment only the controlled partial flow of the liquid is ensured in this way.
According to the most preferred embodiment, in the plant for fractionation, comprising along with the known ones, a loop of partial return of its own residual fraction into the fractionating tower, including a feeding pump and a heating device, sequentially interconnected by pipelines, a second device for resonant excitation of liquid according to the invention is sequentially installed into the loop of partial return of residual fraction.

A method of resonant excitation of liquids, having in their composition bonded hydrogen, is executed by way of oscillatory infiuence onto the liquid for destructive transformation of chemical bonds thereof at the molecular level and includes the transfer of oscillatory energy with the help of a source of mechanical oscillations placed into the liquid.
According to the principal embodiment, resonant excitation of liquid is executed on one of the basic frequencies obeying a common relationship F = F, N '112 , where (1) N _ I - the selected integer, F, = 63.992420 [kHz] - the basic oscillation frequency at N = 1.

The lower boundary of the frequency range from considerations of reasonable adequacy can amount, for example, to unities of Hertz, which corresponds to the maximum values of the integer N of the order of 107 ...10 9.
The method of resonant excitation of hydrocarbon liquids as the specific case of the above-described method of resonant excitation of liquids, having in their composition bonded hydrogen, provides for the use of a rotary hydrodynamic source of mechanical oscillations.
In this case the liquid to be treated is supplied into a cavity 1(Fig. 1) of a working wheel 2 through an intake opening 3 of a stator 4. In the process of rotation of the working wheel 2 the liquid being treated is discharged from the cavity 1 thereof into an annular chamber 5, formed by a peripheral surface 6 (Fig. 3) of the working wheel 2 and a subtending internal coaxial surface 7 of the stator 4, through a series of outlet openings 8, evenly spaced along the peripheral surface 6 of the working wheel 2. Within the annular chamber 5 the liquid being treated continues rotating relative to the central axis 9 and undergoes in this case resonant oscillations of the audio frequency, caused by the interaction of elementary flows, running from the outlet openings 8 of the working wheel 2, between each other and with the coaxial surface 7 of the stator 4.

The actual range of the reasonable values of the integer N is limited in this case by the considerations of the practical expediency and/or technical feasibility in respect of geometrical dimensions and rotation frequency of the working wheel 2, taking into account the strength characteristics thereof.
In the preferred embodiment of the method of resonant excitation of hydrocarbon liquids the rotation frequency of the working wheel is maintained constant with a deviation of 1% from the calculated value.
The device for resonant excitation of hydrocarbon liquids by the above-mentioned method (Fig. 1- 3) comprises a rotor 11 with a shaft 12 resting on bearings 13 and 14 and equipped with a seal 15. On the shaft 12 there is installed at least one blade working wheel 2 rigidly connected thereto, made as a disc 16 with a peripheral annular wall 17.

In the preferred embodiments of the device the radial extent L of the outlet openings 8 of the working wheel 2 is made multiple or more preferably equal to the value S (2 W)-l.
In the most preferred embodiment of the device a means for driving the rotor 11, an electric drive 20 advantageously connected via a coupling 19, comprises a system controlling the rotation frequency n with a deviation of 1% from its calculated value. As such control system (not shown in the drawings) any suitable system from the well known in the art can be used.

If the second atmospheric fractionating tower 27 is provided in the particular plant for fractionation of hydrocarbon liquids, the second similar device 24a can be used for resonant excitation of liquid. In this case the device 24a is sequentially installed between the outlet of a pump 28, feeding residual fraction (stripped oil) from the first tower 21 to the second tower 27, and the inlet of the tower 27, in this case through the second heating device 29. The shut-off-control elements 25a and 26a perform similar functions.
If the third vacuum fractionating tower is provided in the particular plant for fractionation of hydrocarbon liquids, or any known technological equipment for further treatment of residual fraction (not shown in the drawings), the third similar device 24b may likewise be used for resonant excitation of residual fraction after the second tower 27. In this case the device 24b is installed after a pump 30, feeding the residual fraction (residual fuel oil) from the second tower 27 for further treatment. The shut-off-control elements 25b and 26b perform similar functions.
According to the most preferred embodiment, in the plant for fractionation, comprising, along with the known ones, a loop for a partial return into the fractionating tower of its own residual fraction, including a sequentially installed feeding pump 31 and the third heating device 32 interconnected by pipelines, one more similar device 24c is sequentially installed in the loop of the partial return of residual fraction for resonant excitation of the residual fraction being returned after the first tower 21. In the example presented in Fig. 4 the device 24c is installed between the outlet of the feeding pump 31 and the heating device 32.
The shut-off-control elements 25c and 26c perform similar functions.
The operation and service of the described plant for fractionation of hydrocarbon liquids are effected in the ordinary way and differ in comparison with the usual plants of this type only in respect of the control of said shut-off-control elements, which can be performed both manually and in the ordinary way automatically in compliance with the preset technological program.

The list of the kinds of liquids amenable to treatment covers any natural and artificial liquids, having in their composition bonded hydrogen, primarily hydrocarbon liquids, as well as all kinds of solutions, emulsions, suspensions, etc, prepared on the base thereof in the wide range of viscosity and other physical-chemical properties.
The method of fractionation of hydrocarbon liquids implements the above-described method of resonant treatment thereof according to the invention. This method of fractionation is executed by way of distillation and includes the preliminary treatment of liquid with the help of the pre-installed rotary hydrodynamic source of mechanical oscillations, the supply of preliminarily treated liquid into the fractionating tower and the outflow of distilled and residual fractions. In the principal embodiment of the method of fractionation the preliminary treatment of liquid is effected by way of resonant treatment thereof in compliance with the above-described method of resonant excitation of hydrocarbon liquids according to the invention. In the preferred embodiment of the method of fractionation a partial flow is diverted from the general flow of the liquid to be fractionated and is subjected to said preliminary treatment, after which both flows are combined before feeding them into the fractionating tower. The partial flow can amount to 5...80%, preferably 20...50% from the full flow.
In the most preferred embodiment of the method of fractionation including, along with the known methods, a partial return into the fractionating tower of its own residual fraction, the returned residual fraction is likewise subjected to preliminary treatment by way of resonant excitation according to the indention.
The plant for fractionation of hydrocarbon liquids by way of distillation executes the above-described method of fractionation of hydrocarbon liquids according to the invention. Like the known ones, it comprises (Fig. 4) interconnected by pipelines at least one fractionating tower 21, a heating device 22 for a liquid supplied in the column, a feeding pump 23 and a pre-installed rotary hydrodynamic device 24 for preliminary treatment of liquid.
According to the principal embodiment of the plant, the device 24 for preliminary treatment of liquid is made in compliance with one of the above-described embodiments of the device for resonant excitation of hydrocarbon liquids according to the invention. The device 24 for resonant excitation of liquids is sequentially installed between the outlet of the feeding pump 23 and the inlet of the fractionating tower 21, in this case through the heating device 22. At such connection the whole flow of liquid passes through the device 24. In the preferred embodiment of the plant the inlet of the device 24 for resonant excitation of liquid is connected to the inlet of the fractionating tower 21 through a shut-off-control element 25, with whose help it is possible to control, to a certain extent, the partial flow of liquid passing through the device 24. In the more preferred embodiment of the plant the outlet of the device 24 is connected to the inlet of the fractionating tower 21 through a shut-off-control element 26. With the help of both shut-off-control elements 25 and 26 it is possible to control more exactly the partial flow of liquid passing through the device 24 in compliance with the required technological parameters of fractionation.
If the second atmospheric fractionating tower 27 is provided in the particular plant for fractionation of hydrocarbon liquids, the second similar device 24a can be used for resonant excitation of liquid. In this case the device 24a is sequentially installed between the outlet of a pump 28, feeding residual fraction (stripped oil) from the first tower 21 to the second tower 27, and the inlet of the tower 27, in this case through the second heating device 29. The shut-off-control elements 25a and 26a perform similar functions.
If the third vacuum fractionating tower is provided in the particular plant for fractionation of hydrocarbon liquids, or any known technological equipment for further treatment of residual fraction (not shown in the drawings), the third similar device 24b may likewise be used for resonant excitation of residual fraction after the second tower 27. In this case the device 24b is installed after a pump 30, feeding the residual fraction (residual fuel oil) from the second tower 27 for further treatment. The shut-off-control elements 25b and 26b perform similar functions.
According to the most preferred embodiment, in the plant for fractionation, comprising, along with the known ones, a loop for a partial return into the fractionating tower of its own residual fraction, including a sequentially installed feeding pump 31 and the third heating device 32 interconnected by pipelines, one more similar device 24c is sequentially installed in the loop of the partial return of residual fraction for resonant excitation of the residual fraction being returned after the first tower 21. In the example presented in Fig. 4 the device 24c is installed between the outlet of the feeding pump 31 and the heating device 32.
The shut-off-control elements 25c and 26c perform similar functions.
The operation and service of the described plant for fractionation of hydrocarbon liquids are effected in the ordinary way and differ in comparison with the usual plants of this type only in respect of the control of said shut-off-control elements, which can be performed both manually and in the ordinary way automatically in compliance with the preset technological program.
Below is given a concrete example of the practical embodiment of the present invention on the acting oil refining plant, comprising two atmospheric fractionating towers with the use of one device for resonant treatment of hydrocarbon liquids, installed ahead of the first fractionating tower (see Table).
