Abstract
The perturbed-chain polar statistical associating fluid theory (PCP-SAFT) equation of state is applied to correlate phase equilibria for mixtures of hydrogen sulfide (H2S) and carbon dioxide (CO2) with alkanes, with aromatics, and with water over wide temperature and pressure ranges. The binary mixtures of H2S–methane and CO2–methane are studied in detail including vapor–liquid, liquid–liquid and fluid–solid phase equilibria. Very satisfying results were obtained for the binary mixtures as well as for the ternary mixture of H2S–CO2–methane using the (constant) interaction parameters of the binary pairs.
