From the developer:
The mini-REFPROP program is a sample version of the full REFPROP program and is meant for use as a teaching tool in the introduction of thermodynamics to students. It contains a limited number of pure fluids (water, CO2, R134a, nitrogen, methane, propane, hydrogen, and dodecane) and also allows mixture calculations of nitrogen with methane for teaching vapor-liquid equilibrium (VLE).
