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 、H2 S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 present, the main solvent for natural gas decarbonization and desulfurization is the alcohol amine aqueous solution, the most representative of which is N - methyldiethanolamine (MDEA). The authors use a rigorous mixed solvent electrolyte theory to establish the thermodynamic model of gas absorption and absorption heat which can simultaneously calculate the solubility of CO2, H2S and mixed gases in MDEA aqueous solution. The calculated and experimental values are in good agreement
