摘要：

In this paper, the integral inversion curve concept is developed, involving the locus of all points with a vanishing integral Joule-Thomson (J-T) effect DELTAT(h) and isothermal enthalpy change. The structure of the DELTAh(T) surface over the plane of (p(r'), T(r)) is explored. The maximum isothermal J-T effect DELTAh(T) is related to the normal boiling temperature of the gas. The correlation of the integral effect based on real gas data with a low acentric factor is compared with Van der Waals' equation of state closed form predictions. The maximum integral isenthalpic J-T effect DELTAT(h) which does not undergo a phase change during the expansion, is studied via Van der Waals' equation of state.
