Abstract

Water contents of synthetic sweet and sour natural gas–like mixtures and their constituents for wide ranges of temperature and pressure are studied in this work. The perturbed-chain version of statistical associated fluid theory (PC-SAFT) is used to describe the vapor and aqueous phase. In addition to repulsion and dispersion interactions, the 4C association scheme is used to account for self-association between water molecules. Using the PC-SAFT approach, the water contents of methane, ethane, hydrogen sulfide, carbon dioxide, and certain synthetic sweet and sour natural gas mixtures are predicted satisfactorily.
