Part of the Advances in Cryogenic Engineering book series (ACRE, volume 16)


In response to the tremendous interest in correlating thermodynamic properties of fluids at cryogenic conditions, this paper proposes a new equation of state capable of accurately describing PVT, enthalpy, and vapor-pressure behavior of methane and propane for both high-temperature and cryogenic regions. The new equation-of-state form arises from a careful study of isochoric PVT data for methane, and its parameters are determined by the powerful tool of multiproperty analysis [1].
