Book excerpt: Vapor liquid equilibrium (VLE) data were measured for the nitrogen + carbon dioxide binary system at 220 and 240K and for the methane + carbon dioxide system at 219.26, 240, and 270K. Ternary VLE measurements were made for the system N2 + CH4 + CO2 at 220K and 6.080, 9.119 and 12.159 MPa, and 240K at 7.093, 9.119 and 12.159 MPa. The multifluid reference corresponding states method proposed by Teja and Rice was applied to VLE calculations and the results of this method for the binary and ternary systems were compared with the results of the Lee-Kesler corresponding states correlation and the Peng-Robinson equation of state. The multifluid and Lee-Kesler methods give comparable results for the constituent binaries of the N2 + CH4 + CO2 system. However, the multifluid model predictions for the ternary system were superior to the predictions of the Lee-Kesler method. The Peng-Robinson equation of state was found to be better than both corresponding states methods for both binary and ternart system VLE predictions. None of the methods produced good representation near the critical points of the binary and ternary systems.
