Abstract

Razvoj industrije i separacijskih procesa fokusiran je na smanjenje zagađenja okoliša i potrošnje energije. Pojava azeotropa u mnogim sustavima zahtijeva posebne procese koji uključuju potrošnju velike količine energije i otapala što značajno utječe na okoliš. U svrhu unaprjeđenja separacije azeotropa, sve više se razmatra primjenjivost niskotemperaturnih eutektičkih otapala, zbog njihove jednostavne pripreme i ekološke prihvatljivosti U ovom radu istražena je mogućnost razdvajanja binarne azeotropne smjese n-heksana i etanola procesima ekstrakcijske destilacije i ekstrakcije, uz primjenu niskotemperaturnog eutektičkog otapala. Otapalo odabrano za eksperiment je kolin klorid – glicerol (molni omjer 1:2).

Abstract (english)

The development of industries and separation processes focuses on the reduction of pollution and energy consumption. The emergence of azeotropes in many systems requires special processes involving large amounts of energy and severely environmentally impactful solvents. In order to improve the separation processes of azeotropes, the applicability of eutectic solvents is increasingly being considered due to their simple preparation and environmental friendliness. This paper investigated the possibility of separating a binary azeotropic mixture of n-hexane and ethanol by extractive distillation and extraction using a deep eutectic solvent. The solvent selected for the experiment was choline chloride - glycerol (molar ratio 1: 2).
