The models used to predict the solubility of elemental sulfur in acid gas are mostly based on semi empirical formulas established by experiments, which are not applicable to a wide range of temperature and pressure, and few factors are considered.Based on the traditional equation of state, the PR equation was used as a prototype, and the repulsion term of the equation was modified. The thermodynamic parameters of the equation of state were obtained by fitting the experimental results of elemental sulfur solubility. Comparing the prediction results of the modified model with 32 experimental values, the average relative error is 4.01%.The results show that the model can be used to predict the solubility of elemental sulfur in acid gas without relevant experimental data.
