摘要
In this paper five equations of state are tested for checking their ability to predict the Joule-Thomson inversion curve. These five equations of state are: Mohsennia-Modarres-Mansoori (NIMM), Ji-Lemp (JL), modified Soave-Redlich-Kwang (SRK) equation of state by Graboski (MSRK1), modified SRK equation of state by Peneloux and Rauzy (MSRK2), and modified Peng-Robinson,erature branch of (PR) equation of state by Rauzy (PRmr). The investigated equations of state give good prediction of the low-temp the inversion curve, except for MMM equation of state. The high-temperature branch and the peak of the inversion curve have been observed, in general, to be sensitive to the applied equation of state. The values of the maximum inversion temperature and maximum inversion pressure are calculated for each component used in this work. (c) 2007 Behzad Haghighi.
