The model takes the advantages of equations of state to describe the vapor and liquid phases. The solid phase is described by Coutinho's activity coefficient model, i.e., the solid phase is assumed to be orthorhombic solid solution. Impact of pressure on the solid phase is included by coupling solid-liquid Clapeyron relationship with Poynting correction factor. While no adjustable parameter is used, the model satisfactorily predicts the phase boundaries of the synthetic and real systems resembling gas condensate mixtures for wide ranges of pressure and temperature. © 2011 Elsevier B.V. date: 2012 official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-83655201125&doi=10.1016%2fj.fluid.2011.10.019&partnerID=40&md5=87aec0c45e119a5930453377ec337477 id_number: 10.1016/j.fluid.2011.10.019 full_text_status: none publication: Fluid Phase Equilibria volume: 314 pagerange: 60-68 refereed: TRUE issn: 03783812 citation: Nasrifar, K. and Moshfeghian, M.
