【摘要】 提出了一种以四丁基溴化铵（TBAB）为促进剂的水合物分离混合气中 CO₂的方法。研究了进气压力、气液体积比对水合物形成过程压降的影响,考察了水合物形成过程中气相组成的变化,以及进气压力对分离效果的影响。研究结果表明:水合物分离过程通常在1h 之内完成,且气相中 CO₂ 浓度降到最低值8 mol%;系统压降随着进气压力增大而增大,但是随着气液体积比增大而减小,气液体积比为27时系统压降达到最大;在进气压力为4.3 MPa 时分配比达到最大值1.91。更多还原

【Abstract】 A new method of hydrate separation CO₂ with TBAB as a promoter was proposed.The effect of feed pressure and gas liquid volume ratio on system pressure drop was investigated.We also measured the CO₂ concentration in gas phase during the hydrate formation and the effect of feed pressure on the partition coefficient.The results demonstrated that the process of hydrate separation finished in 1 hour,and CO₂ concentration decreased up to 8 mol%.System pressure increased with the increasing of feed pressure and decreasing of gas liquid volume ratio.The largest pressure drop was obtained when gas liquid volume ratio was 27.The partition coefficient increased to a maximum of 1.91 when the feed pressure was 4.3MPa.更多还原
