Predicting the Joule–Thomson inversion curves of natural gas mixtures is important in production, processing, storage and transportation. One consequence of the effect may be the cooling of natural gas in pipelines under pressure drop, which can lead to undesirable glaciations of pipelines[1]. The Joule–Thomson inversion curve (JTIC) is defined as the locus of the points where the Joule–Thomson coefficient becomes zero: 0μJT HPT (1) T, P, and H are the fluid’s temperature, pressure, and enthalpy, respectively. Sign of the JT coefficient determines whether the temperature of a real gas increases or decreases by isenthalpic expansion[2]. The objective of the present paper is prediction of natural mixtures JTIC by SAFT and PC-SAFT EOS.
