To produce LNG, engineers must cool natural gas to -162°C. The phase equilibrium of methane-ethane-propane mixtures is extremely complex. Using REFPROP 9 with the GERG-2008 EOS ensures that flash calculations for LNG heat exchangers are accurate within 0.1%.
Note to users: REFPROP 9 does not include newly developed refrigerants like R1233zd(E) or R1336mzz(Z) – those came in version 10. nist refprop 9
