In the sector, REFPROP is used to simulate the phase behavior of hydrocarbons in pipelines and separators. Its accurate prediction of dew points and hydrate formation temperatures prevents costly operational failures. Similarly, in cryogenics , the software is invaluable for modeling the behavior of liquefied natural gas (LNG), liquid hydrogen, and helium at near-absolute-zero temperatures.

At its core, REFPROP is a property database coupled with a set of highly accurate equation-of-state (EOS) models. Unlike simpler methods that rely on ideal gas laws or generalized charts, REFPROP employs fundamental Helmholtz energy equations for pure fluids. These equations, derived from rigorous experimental data, are capable of representing a fluid’s thermodynamic surface—including density, enthalpy, entropy, and heat capacity—over a wide range of states, from dilute gas to compressed liquid. refprop

The primary strength of REFPROP is its . Because it is maintained by NIST, the underlying data is subject to rigorous, peer-reviewed validation against experimental benchmarks. This gives users confidence that a simulation run in 2024 will yield the same results as one run in 2010. Additionally, its integration with major engineering platforms (MATLAB, Python, Excel via the REFPROP DLL) allows for seamless incorporation into larger simulation workflows.
