目前天然气脱碳和脱硫的主要溶剂是醇胺类水溶液，其中最有代表性的是N－甲基二乙醇胺(简称MDEA)。作者采用严格的混合溶剂电解质理论建立的气体吸收溶解度和吸收热的热力学计算模型，可以同时计算CO2、H2S及混合气体在MDEA水溶液中的溶解度，计算值和实验值符合良好

At the momnent,the main solvents for the removal of carbon dioxide and hydrogen sulfide in natural gas are alkanolaminewater solutions,in which the most widely used one is Nmethyldiethanolamine (MDEA)water solution.In this paper,a strict theory for mixed solvent electrolytic solution is used to establish the thermodynamic model for the calculation of gas solubility and absorption heat.This model can calculate gas solubility of CO2,H2S and mixed gases in MDEAH2O solution,and the calculated values are in good agreement with experimental ones.
