From the water of free state entrained by natural gas and light oil being separated, then raw natural gas enters natural gas compressing
Machine carries out compression and is pressurized to pressure needed for technique, since raw natural gas is in the saturation shape of water and pentane in pressurization
State, once the grease in compression, unstripped gas will condensation come out, separate between the grade of compressor and in final stage separator.
The grease that these greases and initial gross separation of entering the station come out is discharged the interior oil water separator that arrives at a station together and carries out water-oil separating.It separated
Journey is mainly by precipitating principle: because the density of water is greater than the density of light oil, the density contrast of water and light oil can make water and
Light oil is layered after a period of time, and water is below, and light oil will be deposited above, then by the draining valve of operation tank bottom
Water discharge below tank body, will float on light oil above and leaves, play the mesh of water-oil separating.
Since the layering interfaces of water and light oil are not particularly clearly, in the interface meeting of oil reservoir and water layer in storage tank
Form one layer of oil mixing with water layer, the measure taken at present be in order to guarantee in the light oil left in knockout drum it is not aqueous it is necessary to
In the operating process for asking operative employee that waste water is discharged in cesspool, when determining that discharged liquid is light oil, just allow to close
Draining valve, this have the consequence that the certain degree of purity of the light oil stayed is very high, it will not be aqueous, but cause the useless of discharge
In water contain a large amount of light oil, that is to say, in discharge process by gun barrel water and oil water mixture be all discharged into
