REFPROP 9 calculates properties for complex mixtures. It can model pre-defined mixtures like air, natural gas formulations, and standard refrigerant blends. Users can also create custom mixtures of up to 20 distinct components. The software utilizes advanced mixing rules to accurately determine how different molecules interact under pressure. The Science Behind the Software
: It calculates essential values including density, enthalpy, entropy, and vapor-liquid equilibrium (VLE).
The natural gas industry uses REFPROP to determine the compressibility and energy content of gas mixtures during custody transfer, pipeline transport, and liquefied natural gas (LNG) production. 4. Aerospace and Cryogenics
