JT Valve and Turbine are key equipment for LPG production. New model for enthalpy and entropy considering heat insulation efficiency in practice has been presented in this paper. The procedure of analyzing performance of LPG production by using new model also is presented here through an example by using PR-EOS. Results indicate that this method can be used to model phase behavior in the process of JT Vale and turbine very well.
