【摘要】 对WS型混合规则加以适当改进提出一种新的GE型混合规则(MWS型),并将其与PR状态方程相结合应用于多个二元极性体系汽液平衡数据的预测。结果表明,采用PR方程结合MWS型混合规则预测汽液平衡结果一般优于WS型混合规则,能广泛应用于工程实践。更多还原

【Abstract】 In this paper,a new G~E mixing rule(modified WS) is proposed based on the modification of Wong-Sandler(WS) mixing rule,which is combined with Peng-Robinson(PR) equation of state for the prediction of VLE data of many binary polar systems.The results show that VLE estimation method with MWS mixing rule based on PR equation is generally better than those with WS mixing rule.MWS mixing rule can be applied widely in engineering practice.更多还原
