The solubility of ethane in ethylene glycol (EG) has been determined at temperatures in the range 298-398 K at pressures up to 20MPa. The experimental results were correlated by the Peng-Robinson equation of state, and interaction parameters have been obtained for this system. The parameters in the Krichevsky-Ilinskaya equation were calculated from these interaction parameters. (c) 2006 Published by Elsevier B.V.
