摘要

研究了N-甲酰吗啉作为高浓度酸性气体处理溶剂的可行性。使用PC-SAFT方程拟合了酸性气体CO2和H2S在N-甲酰吗啉物理溶剂中溶解的参数，并与聚乙二醇二甲醚溶剂进行了比较。在此基础上，利用通用化工流程模拟软件，设计使用上述两种溶剂提浓高分离酸性气体中的H2S并简单比较了两种溶剂工艺的主要操作能耗。在流程模拟的结果上来看，相对而言，N-甲酰吗啉在高酸气分离中应用有一定的优势，具有工业应用价值。

Abstract

The feasibility of using N>-formylmorpholine as solvent for high concentration acid gas treatment was studied. PC-SAFT equation was used to fit the parameters of acid gas CO2 and H2S in the physical solvent of N-formylmorpholine

and compared with polyethylene glycol dimethyl ether solvent. On this basis

using the general chemical process simulation software

designed to use the above mentioned two solvents to extract high concentration of H2S in the acid gas and simply compare the main operating energy consumption of the two solvents. On the basis of the results of flow simulation

N-formylmorpholine solvent has some advantages in the application of high acid gas separation process

and has industrial application value.
