Vapor-Liquid-Equilibria Of Ch4-Ar-Co System

Isothermal-isobaric vapour-liquid equilibrium compositions were determined for the CH 4 ArCO system at temperatures of 123.4, 137.1, and 164.0 K and, where possible, at pressures of 10.00, 20.00, and 35.00 atm abs. At the above temperatures respectively none, one, and two of the components are supercritical. The equilibrium ratios calculated from the experimental data are found to depend strongly on temperature and pressure, whereas they depend very little on the composition. As a first approximation, the ternary phase diagram is found to be completely characterized by the constituent binary phase diagrams.
