Abstract

Vapor-liquid equilibrium data for binary systems containing carbon dioxide: CO2-C2H6, CO2-C3H8, CO2-n-C4H10, CO2-iso-C4H10, CO2-C2H4, CO2-C3H6 and CO2-1-C4H8 were determined by the vapor recirculation method in the low-temperature range (-41.6°C-0°C). The CO2-C2H4 and CO2-C2H6 systems formed minimum-boiling azeotropes. The modified Redlich-Kwong equation of state was used to calculate vapor-liquid equilibria of these systems. It provided fairly good agreement with experiment.
