A kind of oil-gas-water horizontal three-phase separator and oil-gas-water separation method

Abstract

The invention discloses an oil-gas-water horizontal three-phase separator and an oil-gas-water separation method. The separator is provided with a horizontal tank body, and the inner cavity of the horizontal tank body is provided with a partition plate (5). A buffer (2) is arranged below an inlet pipe (1) on the partition plate, a downcomer (4) is arranged in the lower direction of an escape pipe(7), and a standpipe (3) is arranged between the buffer and the downcomer upwards. The portion positioned above an upper liquid layer of the partition plate inside the inner cavity of the horizontal tank body is a gas phase area (11), the portion positioned below the partition plate and between an overflow plate (6) and a second end socket (92) is an oil-water separation area, and the portion positioned below the partition plate and between the overflow plate and a first end socket (91) is an oil phase area (12). The invention discloses a method for carrying out oil-gas-water separation by adopting the oil-gas-water horizontal three-phase separator. The separator is mainly used for separation of an oil-gas-water mixture with low vapor liquid ratio in the field of oil and gas field oil gastreatment or other fields.

Description

technical field [0001] The invention relates to an oil-gas-water horizontal three-phase separator and an oil-gas-water separation method used in the technical field of oil and gas treatment in oil and gas fields. Background technique [0002] An existing oil-gas-water horizontal three-phase separator is provided with a horizontal tank body, which includes a cylindrical body and two end caps. The cylindrical body is provided with an inlet pipe, an oil outlet pipe, an air outlet pipe and a water outlet pipe, and the inner cavity of the tank body is provided with internal components such as an overflow plate and an inlet diverter. After the oil-gas-water mixture enters the three-phase separator, the inlet splitter initially separates the oil-gas-water mixture into gas-liquid two-phase. The separated liquid phase (including oil phase and water phase) enters the liquid collection area, and relies on the oil-water density difference to separate the oil and water, while the air bu...
