摘要
在t=30~90°C,pCO2=14.88~724.4kPa条件下,测定了CO2在MDEA、MDEA+DEA和MDEA+PZ水溶液中的溶解度,并用Gibbs-Helmholtz方程计算CO2在活化MDEA水溶液中的溶解焓。
Solubilities of carbon dioxide in aqueous MDEAMDEA+DEAMDEA+PZ solutions have been investigated at temperatures ranging from 30 to 90C and CO2 partial pressures ranging from 14.88 to 724.4kPa. Enthalpies of solution of CO2 in the solutions have been calculated from the solubility data.
