Liquid‐liquid‐vapor equilibrium compositions were measured for the nitrogen‐ethane binary and the nitrogen‐methane‐ethane ternary systems from –255° to –219.8°F and at pressures up to 591 psia. A forced‐recirculation apparatus was employed for the determinations. Experimental results were interpreted and correlated. Optimum operating temperature for nitrogen separation has been suggested.
