The effect of system operation parameters and mixtures on the organic Rankine cycle\u2019s performance was evaluated as well. The considered performances were the following: exergy efficiency, specific cost, and specific environmental effect of the net power generation. A multi-objective optimization approach was applied for parametric optimization. The approach was based on the particle swarm algorithm to find a set of Pareto optimal solutions. One final optimal solution was selected using a decision-making method. The optimization results indicated that the zeotropic mixture of cyclohexane\/toluene had a higher thermodynamic and economic performance, while the benzene\/toluene zeotropic mixture had the highest environmental performance. Finally, a comparative analysis of zeotropic mixtures and pure fluids was conducted. The organic Rankine cycle with the mixtures as working fluids showed significant improvement in energetic, economic, and environmental performances.<\/jats:p>","DOI":"10.3390\/e23080954","type":"journal-article","created":{"date-parts":[[2021,7,26]],"date-time":"2021-07-26T09:25:52Z","timestamp":1627291552000},"page":"954","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Exergy-Based Multi-Objective Optimization of an Organic Rankine Cycle with a Zeotropic Mixture"],"prefix":"10.3390","volume":"23","author":[{"given":"Zineb","family":"Fergani","sequence":"first","affiliation":[{"name":"Laboratory of Biomaterials and Transport Phenomena, Department of Process and Environmental Engineering, University of Medea, Medea 26000, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2968-4293","authenticated-orcid":false,"given":"Tatiana","family":"Morosuk","sequence":"additional","affiliation":[{"name":"Institute for Energy Engineering, Technische Universit\u00e4t Berlin, 10587 Berlin, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Djamel","family":"Touil","sequence":"additional","affiliation":[{"name":"Department of Process Engineering, Faculty of Technology, University of Blida, Blida 090000, Algeria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,7,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"509","DOI":"10.1016\/j.energy.2014.09.035","article-title":"Potential of organic Rankine cycle using zeotropic mixtures as working fluids for waste heat recovery","volume":"77","author":"Li","year":"2014","journal-title":"Energy"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"523","DOI":"10.1007\/s11192-009-0146-3","article-title":"Software survey: VOSviewer, a computer program for bibliometric mapping","volume":"84","author":"Waltman","year":"2010","journal-title":"Scientometrics"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/j.applthermaleng.2014.04.073","article-title":"Thermodynamic analysis of waste heat recovery from reciprocating engine power plants by means of Organic Rankine Cycles","volume":"70","author":"Uusitalo","year":"2014","journal-title":"Appl.
