This paper presents new experimental solubility data of hexane in aqueous amine solutions. A set of simple thermodynamics equilibrium cells were used to measure the solubility of hydrocarbons in aqueous amine systems in the range 298 K to 333 K. Analyses of aqueous liquid samples are performed using a gas chromatograph. It was observed that hexane solubility in methyldiethanolamine (MDEA) solutions increased with increasing temperature. Also, increasing amine concentration in the test solution increased the solubility of hexane. A simple model is developed in order to represent the activity coefficient of hexane in the aqueous MDEA solution in the range of 40 wt % to 50 wt % MDEA.
