Résumé :	Accurate knowledge of the sulfur content of gases is a significant factor for prediction of the sulfur precipitation conditions in production of sour natural gases. However, because the concentration of sulfur in the gas phase is very low, the measurement difficulties consequently result in scarce experimental solubility values available in the literature. In this work, application of four commonly used Chrastil-type equations including the original Chrastil, Adachi and Lu, del Valle and Aguilera, and Mèndez-Santiago and Teja, which consider the effects of temperature, density of gas (solvent), and pressures on the sulfur solubility, are investigated to calculate the sulfur content of different gases at various temperature, pressure, and sulfur content ranges. In this study, sulfur is treated as single molecule S8. The Valderrama-Patel-Teja equation of state with non-density dependent mixing rules is used to calculate the densities ofgases. It is found out that the absolute average deviations (AAD %) of the evaluated sulfur contents by the aforementioned equations for 260 investigated experimental values are 21%, 12%, 19%, and 20%, respectively.
