Abstract

An apparatus has been constructed for precisely measuring the solubility of gases in liquids. The equipment is designed for use at temperatures from 0 to 200 o C and pressures up to 18 MPa. Measurements were made on carbon dioxide (1) + dimethyl ether (2) at three isotherms in order to verify the apparatus and techniques by comparing with data from the literature. Measurements were also made on the system carbon monoxide (1)+dimethyl ether (2) which has not been previously studied. The results have been correlated using the Soave-Redlich-Kwong equation of state. Two different local composition mixing rules have been used: the MHV2 mixing rule in combination with the modified UNIFAC model and the MHV2 mixing rule in combination with the original UNIQUAC model
