Technical Report ·
OSTI ID:6688865

The three-phase (SLV) equilibria for the methane + carbon dioxide system was measured at 206, 208, 210, 212, 214, and 216 K, and a complete isotherm was determined at 212 K. The ethane + carbon dioxide system was studied at 204, 206, 208, 209, 210, 212, 213, 214, 216 K and complete isotherms determined at 204, 207, 209, 210, 212, and 216 K. The propane + carbon dioxide system was studied at 208, 210, 212, 214, and 216 K with a complete isotherm measured at 216 K. Preliminary data on temperature, pressure, and mole fraction at the triple points are tabulated. Vapor liquid equilibria data are presented for the ethane + carbon dioxide system at 207, 210, 220, 223.15, 230, 250, 263.15, 270, 213, 230, 250, and 270 K. Binary interaction parameters were fit for the Soave-Redlich-Kwong equation of state. VLE measurements are presented for the nitrogen + ethane, and the nitrogen + carbon dioxide system at 220 K and 270 K. Measurements are also presented for the ternary system nitrogen + carbon dioxide + ethane at 220 K and at three pressures ranging from the pressure of 0.803 (the carbon dioxide + ethane azeotrope) to 9 MPa.
