Vapor−Liquid Equilibria for the Methane−Propane−Carbon Dioxide Systems at 230 K and 270 K

Vapor−liquid equilibria were measured for the binary systems methane−carbon dioxide, methane−propane, and carbon dioxide−propane at 230 K and 270 K. The ternary system methane−carbon dioxide−propane was studied at 230 K and pressures of 0.8, 4.0, and 7.0 MPa; and at 270 K for 2.8, 5.5, and 8.0 MPa. The Peng−Robinson equation of state was used to model the system.
