LHSS equation was set up for meeting the needs of phase behavior calculation of hydrocarbon system of the condensate gas reservoir with low condensate content in China, being a result of national scientific and technological key research project of the “Seventh Five Year Plan”, and it has been successfully used for predicting the high pressure phase behavior of hydrocarbon system of condensate gas reservoir. In order to widen the scope of application of the equation, a thermodynamical enthalpy potential equation of the LHSS equation was derived according to the thermodynamical relation of universality of the enthalpy, and it has been used for calculating the process of adiabatic throttle. In comparison with the result simulated by SHBWR equation which is generally recognized to be the best one used for low temperature separation at present, it is indicated that the LHSS equation may be used for surface low temperature separation simulation and oil gas separation design, thus solving the problem of adopting different state equations for subsurface high temperature and high pressure phase behavior and surface low temperature separation phase behavior respectively.
