Abstract

The invention discloses a gas-liquid separator, which comprises a cyclone foam breaking device, a demisting separation device, a defoaming paddle and a foam buffer chamber are arranged in a cavity of the gas-liquid separator, and a gas outlet and a liquid outlet are arranged outside the cavity of the gas-liquid separator; the cyclone foam breaking device comprises an upper outlet and a lower outlet, the cyclone foam breaking device is used for separating the gas-liquid mixture into a gas mixture and a liquid mixture, the gas mixture escapes from the upper outlet, and the liquid mixture flows out from the lower outlet; the demisting separation device is arranged at the top of the cavity and is used for condensing liquid in the gas mixture; the defoaming paddle is used for defoaming the liquid mixture; the foam buffer chamber is used for storing a liquid mixture higher than a preset liquid level height and performing foam elimination on the liquid mixture in a chemical mode; the gas outlet is formed in the top of the cavity; and the liquid outlet is formed in the bottom of the cavity. According to the gas-liquid separator disclosed by the embodiment of the invention, mechanical and chemical modes are combined, so that the defoaming efficiency of a gas-liquid mixture is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of gas-liquid separation, in particular to a gas-liquid separator. Background technique [0002] Gas-liquid separator is a common device in various industrial and civil applications, which can be used for gas dust removal, oil-water separation and liquid removal of impurities. [0003] Especially in the development and production of oil and gas fields, the gas-liquid separation of foamy crude oil is particularly important. Gas-liquid separators are widely used in oil field transfer stations and joint stations. The gas-liquid separators produced by related technologies can realize the preliminary separation of foamy crude oil. [0004] However, the foamed crude oil that has undergone preliminary separation often cannot achieve complete gas-liquid separation, especially for foams with high viscosity and high content of colloidal asphaltenes in the foamed crude oil, if the foam cannot be elim...
