摘要
以H2S和N2的混合气为模拟天然气,采用自制的小型的气液吸收平衡装置,考察了吸收剂、吸收剂浓度、温度对有机醇胺溶液吸收性能的影响。采用Aspen Hysys和Aspen Plus两大化工工艺流程模拟软件进行模拟计算,发现实验结果与模拟计算结果相吻合。以N-甲基二乙醇胺(MDEA)作萃取剂,吸收剂浓度为2.5 mol/L,吸收剂温度为25℃时,吸收剂的吸收负荷为3183.5 mg/L。
Using H2S/N2 to model natural gas,the effects of absorbent and absorbent concentration and temperature on vapor-liquid equilibrium were studied on a self-made small vapor-liquid absorbent equilibrium apparatus.Two chemical process flow simulation softwares of Aspen Hysys and Aspen Plus were used in simulation of the system.Good agreement between the measured results by this work and the result of computer simulation was obtained.The absorbed burden of absorbent was 3183.5 mg/L by using N-methyldiethanolamine（MDEA） as absorbent at absorbent concentration of 2.5 mol/L and absorbent temperature of 25 ℃.
