Description
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
When the crude oil (G + O + W) flows into the
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).
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.

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
