20.500.12556/DKUM-85069 Recovery of N-butanol from a complex five-component reactive azeotropic mixture This paper proposes a concept of a process design for the separation and recovery of n-butanol from a five-component mixture, consisting of n-butanol, isobutanol, formaldehyde, water and methanol. The mixture is a common waste stream in the production of butylated amino resins; therefore, recovery of n-butanol is crucial to the efficiency of the process. The results show that up to 94% of the n-butanol present in the waste stream can be recovered. Under the studied conditions, 99.76% pure n-butanol can be obtained, while formaldehyde, water and methanol are present only in traces. The energy intensity of the process is estimated at 2.42 MJ/kg of purified n-butanol. The economic analysis of the process shows that the process is economically viable over a wide range of production capacities, as evidenced by high net present values and high return on investment values. recycling n-butanol azeotropic mixture separation process design energy efficiency recikliranje separacija energetska učinkovitost true false true MDPI AG Angleški jezik Slovenski jezik https://www.mdpi.com/journal/processes © 2022 by the authors Znanstveno delo 2023-08-17 14:32:36 2023-08-17 14:32:36 2025-05-13 12:30:07 0000-00-00 00:00:00 2022 0 0 str. 1-15 iss. 2 Vol. 10 14 Feb. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2022-01-25 2022-02-10 2022-02-14 620.92/.98 97390083 10.3390/pr10020364 2227-9717 Recovery_of_N-Butanol_from_a_Comp-Bogataj-2022.pdf Recovery_of_N-Butanol_from_a_Comp-Bogataj-2022.pdf 1 B2E3E0A04106A90946081690C1A5115A 9e162ffe9dd3de07eec4b79ea279ff71909cbdc5bc2265931b18a94aa4821c1c dd1bb575-3cfa-11ee-af21-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=169672 https://www.mdpi.com/2227-9717/10/2/364 0 ead064d5-3cfa-11ee-af21-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=169673 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
