Recovery of alcohols from diluted aqueous solutions is highly energy-intensive. In order to reduce the costs of concentration of alcohols, membrane processes (including membrane extraction) are used. This paper reports the results of ethanol concentration from diluted aqueous solutions using a hollow fiber membrane contactor with ionic liquid. The studies were performed using a contactor with microporous hollow fiber membranes. The membrane creates a barrier between the feed and extracting solvent, also providing a large mass transfer area. In the process, selected ionic liquid presenting different selectivity towards ethanol was used as extractant. The experiments were performed with feed concentrations of ethanol ranging from 1 to 5 wt.% and various feed flow rates ranging from 1 to 8 dm3/h.

Odzyskiwanie alkoholu z rozcieńczonych roztworów wodnych jest procesem wysoko energochłonnym. W celu obniżenia kosztów do zatężania rozcieńczonych roztworów alkoholi wykorzystuje się procesy membranowe, między innymi ekstrakcję membranową. W pracy przedstawiono wyniki badań procesu zatężania rozcieńczonych wodnych roztworów etanolu w kontaktorze membranowym z zastosowaniem cieczy jonowej. W przeprowadzonych eksperymentach wykorzystano kontaktor membranowy z mikroporowatymi membranami kapilarnymi stanowiącymi barierę między roztworem surowym a ekstrahentem i jednocześnie zapewniającymi dużą powierzchnię wymiany masy. W procesie jako ekstrahenta użyto cieczy jonowej wykazującej selektywność w stosunku do etanolu. Omówiono wyniki badań procesu zatężania roztworów etanolu o stężeniach 1 do 5% masowych i natężeniach przepływu nadawy zmienianych w zakresie od 1 do 8 dm3/h.
