FIELD: oil and gas industry.SUBSTANCE: method includes delivery of emulsified oil to an initial water separator, separation of water from emulsified oil in the separator and discharge of a part of water to waste water treatment facilities, further delivery of emulsified oil to buffer separating tanks, separation of gas and water from emulsified oil in the buffer separating tanks, heating of emulsified oil, hot water separation and desalination of emulsified oil and pumping oil to consumers. The liquid level in the buffer separating tank is kept within 40-60% of its height. Emulsified oil is fed to the buffer separating tank at the level of 50% of liquid fill, evenly distributed on the liquid surface along the entire length of the tank, and treated oil in full is delivered to a consumer.EFFECT: increased separation efficiency of oil-water emulsion into oil and water at the stage of initial water separation and larger amount of separated associated petroleum gas.1 dwg |
