脱碳高闪气回收装置项目总结

摘要

Use vacuum pressure swing adsorption process ( VPSA ) to recycle effective gas from high pressure flash gas in four wet decarbonization units . The process not only recycles effective gas ( H2 recycling rate is 92% ) , but also reduces CO2 emission . The economic benefits are great .%通过采用真空变压吸附工艺（V PS A ）回收四套湿法脱碳装置高闪气中的有效成分，既回收了有效气体（H2回收率达92％），减少了二氧化碳排放，还带来了巨大的经济效益。
