管道式分离技术及其在油气行业混合介质分离中的应用

Large amounts of oil, gas, water, sand and mixed liquids are generated in the process of oil and gas production. The heterogeneous separation of mixed media is an important process unit in crude oil mining and refining. Pipeline-type separation technology and equipment use dynamic separation such as centrifugation as the main separation method. A series of core equipment such as spiral tubes, T-tubes, cyclones, tubular coalescers, and cyclonic air flotation tubes have been developed based on centrifugation, gravity, expansion, air flotation and other separation mechanisms and their compound enhancement. A large number of engineering application practices demonstrate that the pipeline-type separation technology has the advantages of modular design, flexible for application, low footprint, high separation efficiency, etc. It can be applied to different scenarios such as oil-gas-water separation, liquid-solid separation, sand removal, sand washing, etc. It has good technical and economic advantages and broad application prospects for the expansion or upgrade of old stations in oil and gas fields.
