Vapor‐liquid equilibrium data for the ternary system propane‐ethane‐carbon dioxide were determined experimentally at 244.3 and 266.5 K by means of a forced recirculation apparatus. The total pressure investigated varied from 87.5 to 433 psia. The data obtained were compared favourably with the values predicted by means of the Redlich‐Kwong equation of state with a modified procedure. The average absolute deviation between the experimental and calculated P is less than 3% and in y less than 0.0140 mole fraction.
