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.
