Vapor-Liquid Equilibria for Binary and Ternary Systems Containing Carbon Dioxide

Vapor-liquid equilibria containing carbon dioxide: CO2-CO, CO2-Ar, CO2-CH4 and CO2-H2-CO were measured by static method at -50°C to 20°C and up to 200 atm. By using these data and the data available in literature, the extent of usefulness of the Benedict-Webb-Rubin equation (hereafter abbreviated as BWR equation) and the treatment of Leland et al. were studied. The BWR equation correctly predicted the vapor-liquid equilibria of inorganic mixtures except in the critical region, while the treatment of Leland et al. was insufficient.
