基于GE混合规则的统计缔合流体方程预测CO2在水中的溶解度
Prediction of the solubility of carbon dioxide in water using statistical associating fluid equation of state based on the GE mixing rule
摘要
Abstract
A thermodynamic model iCPA-HV that based on the improved SRK-CPA associating fluid equation and Huron-Vidal mixing rule is established to predicted CO2 solubility in water,and compared with SRK-HV and PRSV-WS model. The experimental results show that the self-association of water and the cross-associating of CO2-H2O are considered,and the fitting parameters are related to the function of temperature. The iCPA-HV model has the highest accuracy in predicting the solubility of CO2 in water over the range of 278-573 K and 0.1-140 MPa,and the average absolute relative deviation(AARD) is 4.15%,followed by PRSV-WS model with the AARD of 6.01%. The SRK-HV model is not satisfied,with the AARD of 25.41%.关键词
