ABSTRACT
New solubility data of ethane and propane in aqueous methyl diethanolamine (MDEA) and diethanolamine (DEA) solutions were measured at different temperatures and pressures. The data concern vapor liquid liquid equilibrium (VLLE) conditions. In this work, two weight-based concentrations of aqueous MDEA (w = 0.25 and w = 0.50) and one aqueous solution of DEA (w = 0.35) were considered. These concentration types are commonly used in the gas processing industry. The Henry s constant is calculated for each system. In addition, useful correlations are proposed for the solubility, salting-in, three-phase vapor pressure, and activity coefficient at infinite dilution.
