摘要 估算了N-甲酰吗啉(NFM)的临界参数Tc,Pc和偏心因子ω,结合计算出的临界参数,运用状态方程,对文献中CO2,H2S,C2H6和CH4在N-甲酰吗啉溶液中的溶解度进行了考核,并通过相平衡实验数据优化得到了组分间的交互作用参数Kij。考核结果表明,对于以上气体在NFM中的溶解度计算,应用PR状态方程结合vdW混合规则是较好的选择。 The critical temperature, critical pressure, and acentric factor of N-formylmorpholine were estimated by Jacob method. The equations of state (EoS) with those parameters were used to calculate the solubility of CO2, H2S, C2H6, and CH4 in N-formylmorpholine. The interaction parameters Kij of the binary systems were obtained from the vapor liquid equilibrium data. The results showed that PR EoS with vdW mixing rules is in agreement with the experimental data, compared with the other equations of state.
