Vapor‐liquid phase behavior of the hydrogen‐propane and hydrogen‐carbon monoxide‐propane systems

Vapor-liquid equilibria data for the hydrogen-propane binary system and the hydrogen-carbon monoxide-propane system were taken at temperature of −185° to +75°. and under pressures as high as 3000 psi. Vapor-liquid data for the hydrogen-carbon monoxide-propane system are reported at −50°, 0°, and +50°. at pressures of 500, 1000, and 2000 lb./sq.in. abs. for each of the three temperatures. The Krichevsky-Kasarnovsky equation adequately correlated the solubility data of hydrogen in the liquid phase of the hydrogen-propane system. Hydrogen-propane data are compared with the data of two previous studies.
