摘要
实验研究了N-甲基二乙醇胺(MDEA)和乙醇胺(MEA)混合有机胺水溶液吸收煤气中H_2S和CO_2的过程。采用严格的混合溶剂电解质理论建立了气体吸收的热力学计算模型,并用模拟计算软件(ASPEN PLUS)计算了H_2S和CO_2混合气的吸收过程,计算值和实验值符合良好。实验数据和模拟计算结果表明,采用混合醇胺脱硫具有较好的脱硫效率和选择性,符合目前工业装置对脱硫的要求。
Absorption of CO2 and H2S in the coal gas by an aqueous solution of methyldiethanolamine （MDEA）and monoethanolamine （MEA） was investigated experimentally. The thermodynamic model for the calculation of gas absorption was established based on a strict theory for mixed solvent electrolytic solution, and the adsorption of CO2 and H2S in the mixed MDEA-MEA aqueous solution was simulated with the software （ASPEN PLUS）. The calculated values were in good agreement with experimental datas. The Results showed the desulfidation efficiency and selectivity were good using the mixed alkanolamine, which meet the current demand of desulfidation in the industrial production.
