The Patel-Teja equation of state (EOS) was used, the mixture parameters of which were evaluated by equating the excess Gibbs free energy at an effective high pressure condition of 1000 atm to that predicted by the UNIFAC group contribution liquid model. Vapor-liquid (VLE), liquid-liquid (LLE) and vapor-liquid-liquid (VLLE) calculation results over a wide pressure range were presented. Accuracy of predictions was found to be comparable to existing models. ? 1989.journal article10.1016/0378-3812(89)80313-92-s2.0-0024881975https://www.scopus.com/inward/record.uri?eid=2-s2.0-0024881975&doi=10.1016%2f0378-3812%2889%2980313-9&partnerID=40&md5=b94e0400a58d478ce6fd50834d1759ad
