摘要
将固体硫在超临界/近临界含硫化氢酸性流体中的溶解行为视为超临界流体萃取固体的过程.通过对经典混合规则的修正,将PR状态方程应用于固体硫在纯H_2S、CO_2及CH_4中溶解度数据的关联,并对固体硫在含H_2S酸性流体混合物中的溶解度进行了预测,取得了令人满意的结果.
In this paper a high-pressure equilibrium device was developed for measuring the solubility of solids or liquids in supercritical fluids by the static method. The solubility data of solid sulfur in super / near-critical H2S, CO2, CH4 and H2S-rich sour fluid mixtures were measured respectively. Some of the data are published for the first time. The agreement of the experimental results with the data from the literature shows the reliability of the developed device and method.
