摘要: 基于作者提出的求离子组分模型参数的方法,本文直接将Patel-Teja状态方程扩展应用到高压电解质体系.盐-水对的交互作用参数由回归渗透系数数据确定;气体-水对及气体-盐对的交互作用参数通过对二元与三元VLE数据的回归获得.对气体和气体混合物在水及盐水中的溶解度预测结果表明,本文的处理方法是相当成功的.

Abstract: The PT equation of state was extended to high pressure electrolyte solutions by using the method of evaluating ionic parameters proposed by the authors. The model parameters were determined from the literature data. The solubilities of gas and gas mixtures in pure water and brines under high pressures could be predicted with the model developed.
