Abstract: Based on the molecular-thermodynamic model proposed by Edwards et al. a computer program has been established to calculate Vaporliquid equilibria in multicomponent aqueous solutions, applicable to systems containing one or more of following electrolytes: NH₃, H₂S, CO₂, SO₂, and HCN. The maximum ionic strength of the solutions is about 6 mole per 1 kg water, with relative total concentration of about 10-20 mole per 1 kg water, depending on the property of electrolytes. The temperature range is 0-150℃ for systems containing SO₂ and 0-170℃ for other systems. This program, on the whole, can satisty the demand of process design for sour-water strippers. The method is claimed to be able to treat more thoroughly the sour waste-water systems.

摘要： 在埃德华兹(Edwards)等的分子热力学模型的基础上,较合理地选择了基础数据,建立了多组分挥发性弱电解质水溶液的汽液平衡的电算程序。适用范围为:含NH₃、H₂S、CO₂、SO₂、HCN等挥发性弱电解质之一或多种的水溶液体系。溶液的最大离子强度约为6克分子/公斤水;相应的总浓度,依所含电解质的性质而定,约为10～20克分子/公厅水。温度范围:除含SO₂的体系约为0～150℃外,其他体系均为0～170℃。该程序基本上满足酸性污水汽提工艺设计的要求。还指出了今后更全面地开发酸性污水体系(除含上述组分外,还含HCNS、酚类和硫醇类等)的计算方法应遵循的方向。
