Abstract

The compositions of the coexisting phases in the methane-n-pentane system for a pressure range from atmospheric to 2500 pounds per square inch at temperature of 100°7F., 160°F. and 220°F. were studied. Coupling these determinations with data from other sources, gas-liquid equilibrium constants of methane and pentane as well as dew point specific volumes were calculated.

The composition of coexisting phases in the methane, propane-n-pentane system for a temperature of 100°F. and pressures of 200, 500, 1000, 1500, 2000 pounds per square inch in a range of ratios of propane to n-pentane from 0.05 to 1 was studied. From these data, values for the equilibrium constants of methane, propane and pentane were calculated.
