Effort has been made to evaluate the model performance on correlating both the liquid and the vapor phase compositions, which is a demanding task, revealing the model\u2019s and parameters\u2019 limitations, due to the rather low concentrations of heavy compounds in the vapor phase. Initially the model\u2019s binary parameters, which in all cases were temperature independent, were estimated using experimental data for binary systems. Those parameters were used to predict the phase behavior of supercritical CO2 containing ternary and multicomponent mixtures. Since no parameter was adjusted to ternary or multicomponent systems\u2019 data, the reported CPA results for such mixtures are considered as pure predictions. This is the final part of a series of studies [Tsivintzelis et al. Fluid Phase Equilibria 430 (2016) 75\u201392 and 504 (2020) 112337] that complete the parameterization of the CPA equation of state for systems relevant to the biodiesel production, which allows the application of the model to multicomponent mixtures of the relevant processes.<\/jats:p>","DOI":"10.3390\/molecules27185785","type":"journal-article","created":{"date-parts":[[2022,9,8]],"date-time":"2022-09-08T01:40:13Z","timestamp":1662601213000},"page":"5785","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Modeling Binary and Multicomponent Systems Containing Supercritical CO2 with Polyethylene Glycols and Compounds Relevant to the Biodiesel Production"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4907-4794","authenticated-orcid":false,"given":"Ioannis","family":"Tsivintzelis","sequence":"first","affiliation":[{"name":"Department of Chemical Engineering, Aristotle University of Thessaloniki, GR-54124 Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios","family":"Koutsou","sequence":"additional","affiliation":[{"name":"Department of Chemical Engineering, Aristotle University of Thessaloniki, GR-54124 Thessaloniki, Greece"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgios M.","family":"Kontogeorgis","sequence":"additional","affiliation":[{"name":"Center for Energy Resources Engineering (CERE), Department of Chemical and Biochemical Engineering, Technical University of Denmark, DK-2800 Kgs.
