Description

[0001] APPARATUS FOR DECOMPOSING AN EMULSION [0002]

The present invention relates to an emulsion decomposition apparatus, and more particularly, to an emulsion decomposition apparatus for separating oil and water from an emulsion to reduce emulsion and effectively recover oil.

As the dependence of petroleum resources increases, the development of seabed wells is actively under way. In general, oil can be drilled by offshore structures such as FPSO (Floating Product Storage Offshore).

The drilled crude may be mixed with not only oil but also gases such as hydrocarbons, water (seawater) and some solid mud, which are shipped to the ground along with the oil.

Therefore, a separator is generally used to recover oil from drilled crude oil and remove impurities such as gas, water and mud mixed with oil.

The separator can separate gas, oil and water from crude oil by gravity, as in the prior art (published utility model 20-2014-0004127).

1, the separator 10 is provided with an inlet 20 through which crude oil (G + O + W) flows and an outlet 30 through which gas G, oil O and water W are discharged. 40, and 50 may be formed. Further, a panel 60 for separating the oil O from the water W may be formed.

When the crude oil (G + O + W) flows into the separator 10 through the inlet 20 of the separator 10, gas G, oil O and water W can be separated from the crude oil.

The gas (G), the oil (O) and the water (W) may be layered in the separator (10) according to the density. At this time, a part of the oil (O) and the water (W) are mixed at the boundary between the oil (O) and the water (W) to form an emulsion.

As the amount of the emulsion (E) increases, the amount of the oil (O) separated from the crude oil decreases, so that it is necessary to reduce the amount of the emulsion (E) from the crude oil. It is also necessary to separate and recover the oil (O) from the emulsion (E).

Korean Utility Model No. 20-2014-0004127 (Publication Date: July 2014)

The present invention seeks to provide an emulsion decomposition apparatus capable of separating oil from the emulsion in the separator to reduce the amount of emulsion and increase the amount of recovered oil.

The problems of the present invention are not limited to the above-mentioned problems, and another problem that is not mentioned can be clearly understood by a person skilled in the art from the following description.

According to one aspect of the present invention, there is provided an emulsion decomposition apparatus for decomposing an emulsion formed at a boundary between oil and water in a separator, comprising: a spray nozzle for spraying decomposed water to the emulsion so as to separate mixed oil and water in the emulsion; And a supply unit for supplying the decomposed water to the nozzle.

The spray nozzle may further include a water level controller for controlling the water level of the water stored in the separator such that the water level of the water stored in the separator is formed at a position where the emulsion is formed at the position where the water hole is formed, through the connection hole provided on the outer surface of the separator .

In addition, the injection nozzle is coupled to the upper inner surface of the separator, and can move up and down according to the height of the emulsion.

The injection nozzle may include a main pipe extending in the longitudinal direction of the separator and a plurality of auxiliary pipes extending in the width direction of the separator from the main pipe and spaced apart from each other in the longitudinal direction of the separator.

The supply unit may include a decomposition water transport pipe connecting the discharge nozzle for discharging the water in the separator and the injection nozzle, and a control valve for regulating the amount of water supplied to the injection nozzle through the decomposition water transport pipe.

The emulsion decomposition apparatus according to the embodiment of the present invention has the following effects.

First, a greater amount of oil can be recovered by separating the oil and water from the emulsion.

Second, the height of the emulsion in the separator can be adjusted or the height of the injection nozzle can be adjusted, so that the injection nozzle can effectively separate the oil from the emulsion by effectively spraying the decomposed water to the emulsion.

The effects of the embodiments of the present invention are not limited to the effects mentioned above, and other effects not mentioned can be clearly understood by those skilled in the art from the description of the claims.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. It is to be understood, however, that the appended drawings illustrate the present invention in order to more easily explain the present invention, and the scope of the present invention is not limited thereto. You will know.

The present invention is for separating oil (O) and water (W) from the emulsion (E) formed in the separator (10). 2 and 3, the emulsion decomposition apparatus according to the first embodiment of the present invention includes an injection nozzle 100 and a supply unit 200. [

The jetting nozzle 100 can jet the decomposed water 110 to the emulsion E to separate the mixed oil O and water W in the emulsion E. [

At this time, the injection nozzle 100 can be disposed at a position where the emulsion E is formed so that the emulsion E can be effectively decomposed.

Generally, since the amount of crude oil to be decomposed is determined according to the capacity of the separator 10, the position at which the emulsion E is formed in the separator 10 can also be constant. Therefore, the injection nozzle 100 can be fixed at the position where the emulsion of the separator 10 is formed.

Meanwhile, the injection nozzle 100 may include a main pipe 120 and an auxiliary pipe 130 as shown in FIG.

The main tube 120 may extend in the longitudinal direction of the separator 10. [

The auxiliary pipe 130 extends from the main pipe 120 in the width direction of the separator 10 and is spaced apart in the longitudinal direction of the separator 10 and a plurality of auxiliary pipes 130 may be formed.

The main pipe 120 and the auxiliary pipe 130 communicate with each other and the decomposition water 110 can move to the auxiliary pipe 130 through the main pipe 120. And then sprayed toward the emulsion (E) through the injection ports (150) formed in the auxiliary piping (130).

The structure of the main pipe 120 and the auxiliary pipe 130 is not limited to this and various structures may be employed so that the decomposed water 110 is uniformly sprayed to the emulsion E to sufficiently contact the emulsion E and the decomposed water 110 As shown in FIG.

On the other hand, the supply unit 200 can supply the decomposition water 110 to the injection nozzle 100.

The decomposing water 110 injected into the emulsion E in the present invention may be water W stored in the separator 10. [ That is, the decomposition water 110 may use water separated from crude oil. However, the decomposition water 110 is not limited thereto, and water stored outside the separator 10 may be used.

Meanwhile, the supply unit 200 may include a decomposition water moving pipe 210 and a control valve 220.

The decomposition water moving pipe 210 provides a passage through which the decomposition water 110 moves and the decomposition water moving pipe 210 connects the discharge nozzle 50 of the separator 10 and the injection nozzle 100.

In addition, the control valve 220 can control the amount of water W supplied to the injection nozzle 100 through the decomposition water moving pipe 210.

The amount of water W supplied to the injection nozzle 100 may vary depending on the amount of the emulsion E. That is, the amount of water W injected into the emulsion E can be adjusted by adjusting the control valve 220 according to the amount of the emulsion E formed on the separator 10.

4 and 5, the separation of the oil O from the emulsion E when the decomposing water 110 is sprayed onto the emulsion E will be described.

4 is a graph of viscosity change of the emulsion (E) according to the ratio of water. As shown in Fig. 4, in the initial state, the viscosity V of the emulsion E increases as the ratio of water contained in the emulsion E increases.

The viscosity (V) of the emulsion (E) increases until the ratio of the water (W) becomes 60% and reaches a maximum value. When the water (W) further increases in this state, the viscosity It becomes gradually lower.

That is, the reason why the viscosity (V) is lowered is that the oil (O) mixed in the emulsion (E) is separated from the emulsion (E).

The present invention will be described with reference to FIG. It is assumed that the height of the emulsion E formed on the separator 10 before spraying the decomposing water 110 is H1 as shown in Fig. 5 (a).

5 (b), the ratio of the water W to the emulsion E is increased. As a result, the emulsion E is sprayed with the decomposed water 110, (O) mixed with the oil (O) can be separated from the emulsion (E) and moved to the oil (O) layer.

When the oil (O) and the water (W) are separated from the emulsion (E), the emulsion (E) decreases and the height (H2) becomes lower than the height .

The amount of the oil (O) and water (W) contained in the separator (10) can be increased while the amount of the emulsion (E) Therefore, the oil O can be effectively recovered from the crude oil.

The position of the emulsion E and the position of the injection nozzle 100 may not correspond even if the capacity of the separator 10 is constant, unlike the contents described above with reference to FIGS. 2 and 3.

At this time, the height of the emulsion E can be adjusted or the height of the injection nozzle 100 can be adjusted so that the injection nozzle 100 is located at a position corresponding to the emulsion E.

First, an emulsion decomposition apparatus according to a second embodiment of the present invention will be described with reference to FIGS. 6 and 7. FIG. The emulsion decomposition apparatus according to the second embodiment of the present invention includes an injection nozzle 100 and a supply unit 200. The injection nozzle 100 and the supply unit 200 are connected to the injection nozzle (100) and the feeder (200).

In addition, the emulsion decomposition apparatus according to the second embodiment of the present invention may further include a connector 300.

The injection nozzle 100 can communicate with the outside through a connection port 300 provided on the outer surface of the separator 10.

6 and 7, when the emulsion E is positioned at the upper portion or the lower portion of the injection nozzle 100, the injection nozzle 100 is positioned so that the injection nozzle 100 is located in the emulsion (E) It is necessary to move the emulsion (E).

However, in order to move the injection nozzle 100, the connection port 300 connected to the injection nozzle 100 must also be moved.

There is a risk that the water W, oil O and emulsion E stored in the separator 10 leaks to the outside of the separator 10 through the connector 300 when the connector 300 moves up and down . Therefore, in order to move the connector 300, a sealing problem between the connector 300 and the separator 10 must be solved.

The emulsion decomposition apparatus according to the second embodiment of the present invention may further include a level controller 400 so that the injection nozzle 100 is placed on the emulsion layer E without having to solve the sealing problem.

The water level control unit 400 may adjust the water level of the water W stored in the separator 10 such that the emulsion E is formed at a position where the connection port 300 is provided.

The water level adjusting unit 400 includes a moving pipe 410 formed in the separator 10 and communicating with the water outlet 50, a control valve 450 formed in the moving pipe 410, And a storage tank 420 connected to the storage tank 420.

6 and 7, when the emulsion E is positioned above the injection nozzle 100, the discharge port 50 is opened and the water W stored in the separator 10 flows into the moving pipe 410 to the storage tank 420.

As the water level of the water W decreases, the height of the emulsion E falls and can be located at the same height as the injection nozzle 100.

On the other hand, when the emulsion E is disposed below the injection nozzle 100, the water W stored in the storage tank 420 can be introduced into the separator 10 to raise the height of the emulsion E . Therefore, the height of the emulsion E and the height of the injection nozzle 100 can be matched.

In the interior of the separator 10, there may be a sensor (not shown) capable of detecting the height of the water W or the height of the emulsion E. These sensors can be disposed on the inner surface of the separator 10 to determine the height of the water W or the emulsion E.

As described above, the emulsion decomposition apparatus according to the second embodiment of the present invention adjusts the height of the emulsion E so that the injection nozzle 100 is located inside the emulsion E, Can be effectively separated.

8 and 9 are side sectional views showing an emulsion decomposition apparatus according to a third embodiment of the present invention.

The injection nozzle 100 of the emulsion decomposition apparatus according to the third embodiment of the present invention is coupled to the upper inner surface of the separator 10 and can move up and down according to the height at which the emulsion E is formed.

As described above, when the height of the emulsion E is different from the height of the injection nozzle 100, the injection nozzle 100 can be moved toward the emulsion E.

At this time, the connection structure for connecting the injection nozzle 100 and the inner surface of the separator 10 may be a stretching device 180 capable of adjusting the height of the injection nozzle 100.

Since the stretchable and contractible device 180 is connected to the inner surface of the separator 10, there is no sealing problem for preventing the leakage as described above with reference to FIGS. 6 and 7.

Therefore, the height of the injection nozzle 100 can be adjusted according to the position of the emulsion E, so that the injection nozzle 100 can be positioned in the emulsion E layer.

The emulsion decomposition apparatus according to the third embodiment of the present invention can vary the position of the injection nozzle 100 and includes the water level control unit 400 to control the height of the emulsion E Can be adjusted.

Thus, the emulsion decomposition apparatus according to the third embodiment of the present invention can effectively separate the oil O from the emulsion E by allowing the injection nozzle 100 to be located in the emulsion (E) layer.

It will be apparent to those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. . Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
