摘要
内联式脱液器是国外为满足海洋油气开采对分离设备紧凑、高效等新要求而研发的一种气液分离装置。在借鉴国外气液分离器的基础上,设计了直径为203.2 mm的内联式脱液器,并通过Ansys Fluent软件对其气液分离性能进行了三维数值模拟。模拟结果表明,所设计的内联式脱液器具有良好的气液分离效果,其分离效率随液滴粒径及进口流速的增大而增大;当液滴粒径大于70μm、进口流速大于14 m/s时,其分离效率达到99%以上。研究结果可为后续内联式脱液器的结构优化及工程应用奠定基础。
Inline liquid remover is a gas liquid separation device developed abroad to satisfy requirements re- lated to compact and high-efficiency equipment in offshore hydrocarbon production. With consideration to the gas liquid separation developed abroad, inline liquid remover with diameter of 203.2 mm has been designed. By using the software Ansys Fluent, 3D numerical simulation can be performed to determine gas liquid separation perform- ances of the new device. Results of numerical simulation show the newly designed inline liquid remover has favora- ble gas liquid separation performances with separation efficiencies increases with increases in diameters of liquid drops and import velocities; with liquid drops diameters higher than 70 μm and inlet velocity higher than 14 m/s, separation efficiency may be up to 99% or higher. Relevant research conclusions may provide solid foundation for structural optimization and field application of inline liquid removers in the future.
