262随着气液比的增大，常温富甲醇中C02气体含量曲线越来越平缓，增加氮气对常温富甲醇中溶解的C02气体气提效果越来越差，当气液比为 0.9%时，常温富甲醇中的C02气体含量降低到了

0.55%，该含量有利于下游克劳斯酸性气的富集, 同时满足了后系统对常温富甲醇的温降要求。

因此，结合气提氮气用量#气提效果曲线#克劳斯酸性气的富集、常温富甲醇的温降等因素，常温富甲醇气提时气液比应控制在0.8%~1.0%，此区间为常温闪蒸气提的气液比高效拐点区间。

4结束语贫液/准贫液酸性气体脱除工艺相比贫液/半

贫液酸性气体脱除工艺，具有工程投资低、洗涤甲醇循环量小、公用工程消耗低等诸多技术优势。半贫液气提时气液比控制在0.8%~1.2%，有利于准贫液收能力的提升，降低了循环吸收时的动力

；低温富甲醇气提时气液比控制在2%~3%, 有利于系统冷量的收，了富甲醇升温；道系统的动；常温富甲醇气提时气液比控制在 0.8%~1.0%，有利于克劳斯酸性气的富集，满足了后系统对常温富甲醇的

温降要求。

Abstract : The reabsorption process and normal temperature flashing process in lean/quasi —lean liquid acid gas removal unit are introduced in this paper , which analyzes the interaction factors between the two systems during the nitrogen stripping , and determines the main process parameters to be controlled during the gas stripping of the reabsorption a

nd normal temperature flashing system. The efficient inflection point section of gas stripping is founded by adjusting the gas —liquid ratio relationship between the nitrogen stripping and se mi —lean liquid , low temperature enriched methanol , normal temperature enriched methanol , and analyzing the relationship between the gas —liquid ratio and the dissolved CO 2- It is concluded that the gas stripping has the best effect when controlling the gas —liquid ratio during semi —lean liquid stripping from 0.8% to 1.2% , the gas —liquid ratio during low temperature enriched methanol stripping from 2% to 3%, and the gas —liquid ratio during normal temperature enriched methanol stripping from 0.8% to 1.0% , which provide beneficial refer

ence for designing the gas stripping system of lean /quasi —lean liquid acid gas removal unit.Key w ords : acid gas removal ； gas stripping system ； optimization of gas —liquid ratio
