As this membrane process is governed by the differences in the sorption and diffusivities of separated components, close boiling mixtures and azeotropic mixtures can effectively be separated. The dehydration of ethanol is the most common application of hydrophilic pervaporation. The pilot scale properties of hydrophilic composite poly(vinyl alcohol) PVA membrane (PERVAPTM 2200) in contact with wet raw bioethanol are presented. The wet raw bioethanol was composed of ethanol (82.4\u201389.6 wt%), water (5.9\u20138.5 wt%), methanol (2.3\u20136.9 wt%), cyclohexane (0.2\u20132.4 wt%), higher alcohols (0.2\u20131.3 wt%), and acetaldehyde (0.004\u20130.030 wt%). All experiments were performed using a SULZER ECO-001 plant equipped with a 1.5 m2 membrane module. The efficiency of the dehydration process (i.e., membrane selectivity, permeate flux, degree of dehydration) was discussed as a function of the following parameters: the feed temperature, the feed composition, and the feed flow rate through the module. It was found that the low feed flow rate influenced the dehydration efficiency as the enthalpy of evaporation caused a high temperature drop in the module (around 25 \u00b0C at a feed flow rate equal to 5 kg h\u22121). The separation coefficient during pervaporation was in the range of 600\u20131200, depending on the feed composition. The increase in temperature augmented the permeation flux and shortened the time needed to reach the assumed level of dehydration. It was revealed that dehydration by pervaporation using ECO-001 pilot plant is an efficient process, allowing also to investigate the influence of various parameters on the process efficiency.<\/jats:p>","DOI":"10.3390\/membranes14040090","type":"journal-article","created":{"date-parts":[[2024,4,16]],"date-time":"2024-04-16T09:16:33Z","timestamp":1713258993000},"page":"90","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Influence of Process Parameters on the Efficiency of Pervaporation Pilot ECO-001 Plant for Raw Ethanol Dehydration"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6178-3411","authenticated-orcid":false,"given":"Anna","family":"Kujawska","sequence":"first","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Toru\u0144, 7 Gagarina Street, 87-100 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8020-8108","authenticated-orcid":false,"given":"Wojciech","family":"Kujawski","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Toru\u0144, 7 Gagarina Street, 87-100 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wies\u0142aw","family":"Capa\u0142a","sequence":"additional","affiliation":[{"name":"\u0141ukasiewicz Industrial Chemistry Institute, 8 Rydygiera Street, 01-793 Warszawa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7924-4291","authenticated-orcid":false,"given":"Urszula","family":"Kie\u0142kowska","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Toru\u0144, 7 Gagarina Street, 87-100 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marek","family":"Plesnar","sequence":"additional","affiliation":[{"name":"\u0141ukasiewicz Industrial Chemistry Institute, 8 Rydygiera Street, 01-793 Warszawa, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2365-9994","authenticated-orcid":false,"given":"Joanna","family":"Kujawa","sequence":"additional","affiliation":[{"name":"Faculty of Chemistry, Nicolaus Copernicus University in Toru\u0144, 7 Gagarina Street, 87-100 Toru\u0144, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,4,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"423","DOI":"10.1016\/j.memsci.2019.03.076","article-title":"Towards the dehydration of ethanol using pervaporation cross-linked poly (vinyl alcohol)\/graphene oxide membranes","volume":"582","author":"Galiano","year":"2019","journal-title":"J.
