Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crude oil tank,

The present invention relates to a crude oil tank water cleaning method and system, and more particularly, to a crude oil tank water cleaning method and system for removing sludge accumulated in a crude oil tank storing crude oil using water.

Crude oil pulled from the underground is temporarily stored in the crude tank before it is put into the tanker and before entering the refinery for refining. When the inflow and outflow of crude oil into the crude oil tank are repeated, the sludge accumulates on the bottom of the crude oil tank and is fixed. When the amount of accumulated sludge is increased, the storage capacity of the crude oil tank is reduced, and at some point, the sludge should be removed from the crude oil tank.

Prior Art No. 10-1224010 entitled " Automatic Crude Oil Storage Device for Crude Oil Storage Tank ", Registered Patent No. 10-0475172 "Sludge Removal in Oil Tank and Oil Oil Recovery Method" In the prior art, a heat medium oil of an oil component was used to melt the sludge of the oil component. However, if the crude oil tank is cleaned using thermal oil, it takes a long time to melt the sludge, and a large amount of harmful gas is generated in the crude oil tank. When such a gas is discharged into the atmosphere, environmental pollution occurs.

In addition, since all the sludge is difficult to be removed, a considerable amount of sludge is left in the crude oil tank, and the operator must go into the crude oil tank to manually remove the oil sludge, and there is a high possibility of a safety accident because the crude oil tank is filled with noxious gas.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crude oil tank cleaning method and system for cleaning a crude oil tank using water.

The present invention also relates to a crude oil tank water cleaning method and system thereof that can prevent environmental pollution by treating harmful gas generated in a crude oil tank cleaning process.

The present invention also relates to a crude oil tank water cleaning method and system for efficiently removing sludge by sequentially increasing the temperature of water introduced into a crude oil tank.

The present invention relates to a process for supplying cleaning water to a crude oil tank, A gas discharge process for discharging gas generated in the crude oil tank to the outside; A high-pressure water discharging step of discharging high-temperature and high-pressure high-pressure water into the crude oil tank so that crude oil in the crude oil tank is mixed with the washing water; A crude oil discharging process for discharging the crude oil floating on the mixed water mixed with the crude oil to the outside; A step of raising the washing water using the mixed water discharged from the floating crude oil to a predetermined temperature and then injecting the washing water into the crude oil tank; And a process of injecting the rotating water into the crude oil tank depending on whether the concentration of the crude oil contained in the washing water using the mixed water is less than a predetermined value.

Here, the gas discharging process includes separating LPG and gasoline from the exhaust gas through a liquefaction process; Contacting the gas separated by the LPG and gasoline with water; Hydrogen generated after contact with water may be discharged to the atmosphere and oxygen and nitrogen may be used to produce nitrogen for input to the crude oil tank.

In addition, the process of charging into the crude oil tank repeats the process of raising the washing water using the mixed water discharged from the floated crude oil to a predetermined temperature and then injecting it into the crude oil tank in one cycle. Can be repeated until the temperature of the water reaches a predetermined temperature.

According to another aspect of the present invention, there is provided a method of controlling an internal combustion engine including a pump for injecting high-temperature washing water into a crude oil tank and discharging high-pressure and high-pressure high-pressure water into the crude oil tank so that crude oil in the crude oil tank is mixed with the washing water; A crude oil discharging means for discharging the crude oil floated on top of the mixed water in which the crude oil is mixed; An explosion-proof ventilator for discharging gas generated in the crude oil tank to the outside; A boiler for raising the washing water using the mixed water discharged from the floating crude oil to a predetermined temperature; And a rotating water input means for inputting rotating water into the crude oil tank depending on whether the concentration of the crude oil contained in the washing water using the mixed water is less than a predetermined value.

A nitrogen generator for generating nitrogen; A cooling tower for separating LPG and gasoline from the exhaust gas through a liquefaction process; The LPG and the gasoline may be separated from each other by using water to discharge hydrogen into the air, oxygen and nitrogen to the nitrogen generator, and sulfur dioxide and hydrogen sulfide to prevent the air from being discharged into the atmosphere.

In addition, the process of raising the washing water using the mixed water discharged from the floating crude oil to a predetermined temperature and then charging the crude oil tank into the crude oil tank is repeated in one cycle. The boiler raises the temperature of the water by a predetermined temperature every time one cycle is repeated , And repeats until the temperature of the water reaches a predetermined temperature.

Since the present invention cleans the crude oil tank using only water without using heat medium oil or chemical cleaning material, it is possible to reduce gas generation in the crude oil tank cleaning process.

In addition, it is possible to prevent environmental pollution by preventing the emission of harmful gas, which causes environmental pollution, to the atmosphere by treating the gas generated in the process of cleaning the crude oil tank, and it is possible to recycle gas, which is efficient.

In addition, it is possible to control the amount of gas generated during the cleaning process of the crude oil tank by controlling the temperature of the water such as the washing water which is inputted to the crude oil tank in order, and it is possible to control the amount of gas generated during the crude oil tank washing process. Water is efficient because it can be recycled.

In addition, since recycled waste oil, wastewater, and waste generated in the crude tank cleaning process can be recycled, only the solid incineration water that is difficult to recycle can be incinerated, which is excellent in recyclability.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The present invention is not limited to the embodiments described herein, but may be embodied in various different forms. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

In explaining the present invention, the water used in the cleaning process is divided into washing water, high-pressure water, mixed water, and rotating water. In order to more specifically explain the use of water used in the washing operation, It is.

1 is a configuration diagram of a crude oil tank 10 water cleaning system according to an embodiment of the present invention.

1, the crude oil tank 10 water cleaning system includes a crude oil tank 10, a cooling tower 120, a gas tank 130, an oil tank 140, a nitrogen generator 150, A washing water storage tank 110 and a boiler 100, and may further include a pump (not shown).

The crude oil tank 10 stores crude oil, and sludge having crude oil, sand, mud, etc. adhered to the bottom of the crude oil tank 10 is accumulated. The crude oil tank 10 has a plurality of manholes 160 and 170 along the periphery thereof and each of the manholes 160 and 170 is a passage through which the hose and pipe are mounted in the crude oil tank 10. For this purpose, the inside of each of the manholes 160 and 170 can be divided into a plurality of parts. In FIG. 1, five parts are shown, but the number and usage of each part can be changed if necessary. 1 may include an oil skimmer 193 (not shown), a gas discharge 180, a nitrogen input 183, a wash water input and discharge 186, a jet spray Jet spray nozzle (not shown), and a side scuttle 196 (not shown).

In the present invention, the manholes 160 and 170 may be used differently. For example, the first manhole 160 is used for injecting an inert gas such as nitrogen, washing water, high-pressure water, and the like, and a second manhole 170 is used for discharging gas, discharging washing water, Can be used. When the number of manholes is three or more, only the second manhole 170 can be used to operate the first manhole 160 from the third manhole (not shown) and to discharge the crude oil from the crude oil tank 10 to the outside.

Although the washing water and the high-pressure water used for cleaning the crude oil tank 10 are supplied using the manholes 160 and 170, the rotating water is supplied from the top of the crude oil tank 10 to the bottom without passing through the manholes 160 and 170 And may include a rotation number input unit 165 for this purpose.

The cooling tower 120 separates the gas generated during the cleaning operation from the oil tank 140 into an oil such as LPG, gasoline and other gases through a liquefaction process. The separated oil is stored in the oil tank 140, and the gas is delivered to the gas tank 130.

The gas tank 130 has a water tank (not shown) in which water is separated, and the gas separated from the oil is supplied to the water. At this time, the harmful gas which causes environmental pollution by chemical reaction with water, It is possible to prevent discharge to the atmosphere.

The nitrogen generator 150 generates nitrogen, and nitrogen is injected into the crude oil tank 10 to prevent a fire explosion accident. Inside the crude oil tank 10, there is a possibility that an explosion accident may occur due to the flammable gas generated in the cleaning process due to the high flammable gas generated from the crude oil. In order to prevent this, nitrogen is injected into the crude oil tank 10 . Other gases corresponding to an inert gas other than nitrogen may be used.

The washing water storage tank 110 stores the water required for washing the crude oil tank 10 and stores the discharged water in the crude oil tank 10 and supplies the water to the boiler 100 for washing the crude oil tank 10 To be reused. At this time, it is possible to carry out the washing operation by using the water stored in the washing water storage tank 110 as it is, or by performing the water separation process of separating the crude oil component from the stored water and then performing the washing operation using water, A configuration may be additionally provided.

The boiler 100 is used to increase the temperature of water supplied to the crude oil tank 10, and high temperature water is required to perform the method of cleaning the crude oil tank 10 of the present invention. At this time, the high temperature corresponds to the temperature of water required to remove the sludge in the crude oil tank 10, and corresponds to the temperature at which the sludge such as solidified crude oil can be melted, preferably 30 to 80 ° C.

A pump (not shown) is used to introduce or discharge water such as washing water into the crude oil tank 10, and a water supply pump, a drain pump, a high pressure pump, or the like can be used.

2 is a view for explaining the treatment of the gas generated in the process of cleaning the crude oil tank 10 according to the embodiment of the present invention.

Since crude oil contains not only oil components but also hydrogen (H₂), nitrogen (N₂), oxygen (O₂), sulfur dioxide (SO₂) and hydrogen sulfide (H2S), gas is generated in the course of cleaning the crude oil tank, , Hydrogen sulfide, etc. are discharged into the atmosphere, environmental pollution occurs. Therefore, the present invention can further carry out a gas treatment process to prevent environmental pollution.

2, the gas generated during the cleaning process of the crude oil tank 10 is filled in the crude oil tank 10, so that the inside of the crude oil tank 10 is removed by using a flame proof ventirator (not shown) And transfers the gas to the cooling tower 120 through the second manhole 170. The cooling tower 120 separates the collected gas into LPG, gasoline and other gases through a liquefaction process, transfers the oil to an oil tank (not shown), and supplies the gas such as nitrogen, oxygen, hydrogen, sulfur dioxide, Is compressed by an air compressor (230), and then is delivered to a gas tank (130). In the gas tank 130, sulfur dioxide and hydrogen sulfide are allowed to remain in water in a water tank (not shown) through a chemical reaction with water to prevent discharge to the atmosphere, and oxygen, hydrogen, and nitrogen are discharged out of the water. Thereafter, the hydrogen is discharged to the atmosphere, and the nitrogen and oxygen are sent to the nitrogen generator 150 to generate nitrogen, and the nitrogen produced in the nitrogen generator 150 is used for the first manhole 160, And can be introduced into the crude oil tank 10 through the manholes 200 and 210. At this time, the third and fourth manholes 200 and 210 correspond to the manhole to be operated as the first manhole 160.

FIG. 3 is a view for explaining circulating supply of water for cleaning the crude oil tank 10 according to an embodiment of the present invention.

3, high-temperature washing water is introduced through the first manhole 160, the third and fourth manholes 200 and 210 to remove the sludge in the crude oil tank 10, It is preferable to inject the solution at a rate of about 1 to 3 times. When the washing water is introduced, the crude oil in the sludge is mixed with the washing water to be mixed with the washing water. Since the crude oil in the mixed water is lower in specific gravity than water, it is floated up to the mixed water. In addition, high-pressure high-pressure water of high temperature and high pressure can be discharged into the crude oil tank 10 so that the crude oil quickly melts into the washing water and smoothly mixed with the washing water. The crude oil floating on the mixed water is discharged from the crude oil tank 10 through the second manhole 170 using an oil skimmer (not shown), and the discharged crude oil is stored in the oil tank 140, (Not shown), other mechanisms for discharging the crude oil floating on the mixed water may be used.

On the other hand, if the crude oil tank 10 is cleaned using hot water, it is necessary to adjust the amount of gas generated since the gas is generated. To this end, the present invention increases the temperature of the water supplied to the crude oil tank 10 sequentially at a predetermined temperature interval, and then inputs the water. For example, initially, washing water is introduced into the crude oil tank 10 at a temperature of 30 ° C. through the first manhole 160, the third and fourth manholes 200 and 210, 2 manhole 170 and the mixed water discharged from the crude oil is transferred to the washing water storage tank 110 through the second manhole 170. [ At this time, the mixed water from which the crude oil is removed is not the same as the initially introduced washing water, but since the crude oil is considerably removed, it can be recycled as washing water for the next washing process. Hereinafter, The mixed water from which a crude oil is removed is expressed in the same manner as the washing water.

The washing water storage tank 110 transfers the supplied washing water to the boiler 100. The boiler 100 raises the temperature of the washing water by 10 DEG C and sends the washing water of 40 DEG C to the first manhole 160, And is introduced into the crude oil tank 10 through the manholes 200 and 210. When the washing water is introduced, the crude oil in the sludge is mixed with the washing water, and the oil is floated on the mixed water. As described above, the floating oil is discharged to the outside and stored in the oil tank 140. The washing water from which the crude oil has been removed is transferred to the washing water storage tank 110. The washing water storage tank 110 transfers the supplied washing water to the boiler 100 And the boiler 100 raises the temperature of the washing water by 10 ° C again and then puts the washing water of 50 ° C into the crude oil tank 10. When the temperature of the washing water exceeds 50 ° C, the paraffin contained in the crude oil melts between 47 and 65 ° C. Therefore, the crude oil floating on the mixed water contains paraffin. To the outside.

The process of washing the crude oil tank 10 by circulating the washing water can be repeated until the temperature of the washing water finally introduced into the crude oil tank 10 reaches a predetermined temperature such as 80 ° C. The washing water supplied to the crude oil tank 10 at the same temperature may be used to determine the amount of washing water to be supplied to the crude oil tank 10 in advance or to determine the supply time of the washing water in advance, Can be determined and operated in advance. In addition, the high-pressure water uses water having a temperature equal to the temperature of the washing water to be introduced.

4 is a view for explaining the cleaning of the crude oil tank 10 using the number of revolutions according to an embodiment of the present invention.

Referring to FIG. 4, although the washing water transferred to the washing water storage tank 110 has the crude oil removed, a certain amount of crude oil remains because it is difficult to completely remove the crude oil from the mixed water. At this time, by measuring the concentration of the crude oil in the washing water supplied to the washing water storage tank 110, the progress of the washing operation of the crude oil tank 10 can be known. Therefore, if the concentration of the crude oil in the washing water stored in the washing water storage tank 110 is lower than a predetermined reference value, it can be seen that most of the crude oil is removed from the sludge in the crude oil tank 10.

On the other hand, since the sludge in the crude oil tank 10 includes not only crude oil but also sand and mud, the number of revolutions is input to remove the residual sludge. The number of revolutions is the same as the temperature of the finally introduced washing water, and a jet spray nozzle can be used. Further, a rotary member (not shown) may be used to discharge a large number of revolutions to the bottom with a strong water pressure while rotating the rotary member. The sludge attached to the inside of the crude oil tank 10 can be removed and the mixed water can be collected at the edge of the lower portion of the crude oil tank 10 and can be easily discharged to the outside, And stored in the storage tank 110 for storage.

If the inside of the crude oil tank 10 is cleaned by injecting the rotational number, the washing water stored in the washing water storage tank 110 is put into the other crude oil tank 20 because the washing water is no longer needed in the crude oil tank 10 being cleaned The cleaning operation can be carried out. At this time, the number of revolutions and residual mixed water introduced into the crude oil tank 10 being cleaned may not be stored in the washing water storage tank 110 but may be transferred to the crude oil tank 20 which needs to be cleaned immediately.

When the process of washing the inside of the crude oil tank 10 with water is completed, the finishing work is performed. In the finishing work, the operator enters the inside of the crude oil tank 10 to remove the scum that has not been removed, And removing the remaining mixed water to complete the cleaning operation. In the finishing work, since the inside of the crude oil tank 10 is cleaned by the water in the previous process, the crude oil is hardly left, and since the gas is discharged and processed, the worker can work without wearing the mask. Since the present invention can clean the crude oil tank 10 without input of manpower, the finishing work can be selectively carried out.

5 is a flowchart for explaining a method of cleaning a crude oil tank 10 according to an embodiment of the present invention.

Referring to FIG. 5, an inert gas is injected into the crude oil tank 10 before cleaning the crude oil tank 10 to prevent a fire explosion accident (500). Thereafter, the high-temperature washing water is introduced into the crude oil tank 510, the generated gas is discharged to the outside 520, and the high-pressure water is discharged to mix the crude oil with the washing water 530. At this time, the gas discharge may be performed after the discharge of the high-pressure water, and the degree of gas generation inside the crude oil tank 10 may be measured and selectively applied.

When the crude oil is mixed with the washing water by discharging the high-pressure water, the crude oil floating on the mixed water is discharged to the outside of the crude oil tank 10 (540) and discharged for storage in the washing water washing water storage tank 110 from which the crude oil is removed 550). The washing water stored in the washing water storage tank 110 is sequentially raised in temperature at a predetermined temperature interval through the boiler 100 and then put into the crude oil tank 10. If the crude oil concentration of the washing water stored in the washing water storage tank 110 is higher than a predetermined reference value (NO in 560), the process of continuously increasing the temperature of the washing water is continued. Otherwise (YES in 560) The remaining sludge is removed 570 by injecting the rotating water into the crude oil tank 10 and the washing water containing the mixed water in the crude oil tank 10 is charged into another crude oil tank 20 requiring washing 580 ), A finishing operation is performed on the crude oil tank 10 being cleaned (590).

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications may be made therein without departing from the scope of the invention as defined by the appended claims. Should be construed as falling within the scope of protection of the present invention.
