A gas-liquid separator

Abstract

The invention provides a novel gas-liquid separator comprising a liquid storage cavity, and a cyclone separation section and a deep gas-liquid separation section which are arranged at the top of the liquid storage cavity and are communicated with the liquid storage cavity, wherein a base is arranged at the bottom of the liquid storage cavity, a gas-liquid separator inlet is formed in the cyclone separation section, and a cyclone column is arranged in the cyclone separation section; a separator outlet is formed in the deep gas-liquid separation section, a blade type separation box is arranged on the inner end surface of the separator outlet, the lower end of the blade type separation box is connected with a blade type separation box liquid discharge pipe which is communicated with the liquid storage cavity, the other end of the blade type separation box, relative to the separator outlet, is provided with a wire mesh demister, and the wire mesh demister is communicated with the blade type separation box; and a production liquid discharge opening is also formed in the bottom of the liquid storage cavity. The novel gas-liquid separator provided by the invention can be used for greatly improving the operation stability of gas fields, and re-purification of gas is achieved so as to ensure that gas to be purified is subjected to deep gas-liquid separation; and the purpose of increasing the gas-liquid separation efficiency of a multi-stage baffle plate liquid removal component can be achieved.

Description

technical field [0001] The invention relates to a gas-liquid separator, in particular to a separator for gas-liquid separation at a gathering and transportation station in the petroleum and natural gas exploitation industry. Background technique [0002] During the development of natural gas fields, because some gas wells have high water production and contain a certain amount of condensate oil and other impurities, gas-liquid separation needs to be carried out at the gas gathering station. In the development of some gas fields, due to the needs of the gas gathering process, the operating pressure of the station will vary greatly with the change of the season or production period. At the same time, considering the development cost of the gas field, the gas gathering station is generally only equipped with a gas-liquid separator. (hereinafter referred to as the separator), the separation element is set in the separator to improve the separation efficiency. Conventional separ...

AI Technical Summary

Problems solved by technology

Conventional separators have the following two problems: First, the setting of the separation element greatly reduces the liquid storage space of the separator. When facing a slug flow in the gas production pipeline, the liquid quickly enters the separator, and the separator cannot meet the storage requirements. , the liquid will be brought into the downstream pipeline, so that the downstream compressor and other equipment cannot operate normally, affecting the normal production of the station; the second is that the change of pressure with the season or production period makes the operating condition range of the separator wide, and the conventional separator Difficult to achieve ideal separation effect
