摘要
本文导出了计算CO2在MDEA和MDEA-PZ水溶液中溶解度的简化计算式。以自拟的K1(MDEA解离常数)、K2(PZ的一级解离常数)计算的CO2溶解度与文献实验值、模型计算值作了比较,结果证明精度良好,可满足工程设计要求。
A simplified method for calculation of the solubility of CO_2 in MDEA and MDEA-PZ aqueous solution is suggested in this paper. MDEA dissociation constant and PZ first order dissociation constant required for calculation are correlated.The calculated value of CO_2 partial pressure agree well with the experimental value.The simplified model can be used conveniently in the process of DEA or MDEA-PZ aqueous solution with a satisfactory accuracy.
