Vapour-liquid equilibrium equations for hydrocarbon-oil mixtures.

Summary

The world of refrigeration is now reviewing the use of hydrocarbons (propane and isobutane) as working fluids for heat pump and refrigeration systems. With the arrival of CFCs in the 1930's, these fluids were discarded on an almost exclusively flammability criterion basis. However, the trend now has reversed as CFCs are being phased out. Even though their thermodynamic and transport properties have been extensively studied, little is known on how hydrocarbons are affected by the presence of oil. The present article suggests an extension of a known methodology, originally developed for CFC-oil mixtures, to deal with hydrocarbon-oil mixtures.
