ResumoAbstract Vapor‐liquid equilibrium compositions were measured for the methane‐ethylene binary at — 156.1°, — 173.1° and — 193.1° F, the methane‐ethane binary at — 173‐1° F, and the methane‐ethylene‐ethane ternary at — 173.1° F and at pressure up to 330 p.s.i.a. A forced recirculation apparatus was employed for the determinations. Liquid activity coefficients, γ, were evaluated by means of a modified Redlich‐Kwong equation of state incorporating with binary interaction constant and correlated by the Redlich‐Kister equation. Equilibrium data for the ethylene‐ethane binary system at — 173° F were predicted by the modified Redlich‐Kwong equation of state for correlating the γ values of the methane‐ethylene‐ethane ternary system.
