摘要/Abstract

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.

Abstract: In this paper the dissolving behavior of solid sulfur in super / near-critical H2S-containing sour fluid mixtures is treated as a supercritical fluid extraction of solids. By modifying the conventional mixing rule, a new thermodynamic model based on PR equation of state for solubility calculations is developed. The new model is used to correlate solubility data of solid sulfur in pure H2S, CO2 and CH4 as well as to predict sulfur solubility in H2S-containing sour fluid mixtures.It is shown that the proposed model is in agreement with the experimental data of this work and those from the literature.
