摘要：

New experimental solubility data of heptane in aqueous amine solutions is presented. Simple equilibrium cells were used to measure the solubility of heptane in aqueous amine systems in the range: 298-328 K. Aqueous liquid samples were analyzed using a gas chromatograph. It was observed that heptane solubility in Methyldiethanolamine (MDEA) solutions increased with increasing temperature. Also, increasing amine concentration in the tested solution, the solubility of heptane increased. Simple models were developed in order to represent the activity coefficient of heptane in the aqueous MDEA solution in the range of 40-50 wt % MDEA. The Henry's law-based model allowed for a more direct comparison between the solubilities in pure water and in the aqueous solution of MDEA. The obtained heptane solubility data were compered to predicted data using group contribution equation of state model (GCA-EoS). (C) 2016 Elsevier B.V. All rights reserved.
