Gas-liquid separation system

Abstract

The invention discloses a gas-liquid separation system which comprises a stock solution input pipe (I), a pre-separator (A), a spiral-flow type gas-liquid separator (B) and a mist catcher (C), wherein the pre-separator (A) comprises a first columnar cylinder (1) which is provided with a first input pipe (11) and a first drain pipe (12); the spiral-flow type gas-liquid separator (B) comprises a second columnar cylinder (2) which is provided with a second gas outlet pipe (22), a second input pipe (21) and a second drain pipe (23); the top of the stock solution input pipe (I) is communicated with a first end (21a) of the second input pipe (21); the middle part of the second input pipe (21) is communicated with the first input pipe (11); and the second gas outlet pipe (22) is communicated with a third input pipe (31) of the mist catcher (C). Compared with the prior art, the gas-liquid separation system has the advantages of ideal separation effect, higher purity of the speared phase objects, higher metering capability, pre-separation effect on the liquid phase object and high operating efficiency in the case of lower content of the gas phase object.

Description

technical field [0001] The invention belongs to the technical field of fluid separation, in particular to a gas-liquid separation system capable of finally realizing gas-liquid two-phase separation. Background technique [0002] At present, in the oil field surface gathering and transportation system, various separators are mainly used to separate the natural gas and oil-water mixture in the gas-liquid mixture produced by the oil well, and then realize liquid metering or production metering. Traditional gas-liquid separators only rely on gravity to naturally separate gas and liquid. The final output liquid still has a high gas content, and the separation effect is not ideal, and the separation speed is slow and the efficiency is low. [0003] In order to improve the purity of the separated phase and ensure the separation performance, many gas-liquid separators currently in use mostly use a device or equipment to adopt some physical treatment methods, such as gravity method, ...

AI Technical Summary

Problems solved by technology

In practical application, during the high-speed rotation of the gas, it is easy to bring out the liquid droplets, so that the final output gas phase contains more liquid, and the separation effect is still not ideal. Unified into the cyclone gas-liquid separator, the work efficiency is not very high, so further improvement is needed
