摘要

The solubility of hydrogen sulfide (H2S) and carbon dioxide (CO2) in diethylene glycol (DEG) has been determined at temperatures in the range 298-398 K at pressures up to 7.5 MPa (for H2S) or 20 MPa (for CO2). The experimental results were correlated by the Peng-Robinson equation of state, and interaction parameters have been obtained for these systems. The parameters in the Krichevsky-Ilinskaya equation were calculated from these interaction parameters. The vapor-phase compositions predicted by the equation of state have been compared with published data. (C) 2000 Elsevier Science B.V. All rights reserved. [References: 14]
