Abstract:V okviru magistrskega dela smo pripravili in preučili različne sheme separacijskih alternativ za separacijo n-butanola iz zmesi formaldehid, metanol, izo-butanol in voda ter izvedli njihovo simulacijo s programom Aspen Plus V10. Simulirali smo štiri različne procesne sheme. Tri procesne sheme smo sintentizirali na principu zaporednih destilacijskih kolon, četrto shemo pa smo sintentizirali na principu azeotropne destilacije. Četrto procesno shemo smo simulirali dvakrat. V primeru prve simulacije smo kot glavni kriterij postavili čim boljšo separacijsko učinkovitost, v drugi simulaciji pa smo postavili kot glavni kriterij ekonomsko ugodnost sheme. Raziskali smo vpliv obratovalnih parametrov na čistost n-butanola in porabo pogonskih sredstev. Iz rezultatov je razvidno, da obratovalni parametri, razen pretoka destilacijskega ostanka v preučevanih območjih nimajo velikega vpliva na čistost pridobljenega n-butanola, imajo pa velik vpliv na porabo pogonskih sredstev. Nadaljnje smo sintentizirane sheme ovrednotili z ekonomskega in separacijskega vidika. Najvišji izkoristek procesa in najvišjo čistost n-butanola smo dosegli pri simulaciji separacije dane zmesi z uporabo treh zaporednih destilacijskih kolon. Končni produkt je n-butanol s čistostjo w = 99,9 % . Izkoristek separacije dane procesne sheme je bil 99,9 %. Najnižji izkoristek procesa, če ne upoštevamo osnovne procesne sheme z eno destilacijsko kolono smo dobili pri simulaciji procesne sheme z dvema destilacijskima kolonama (93,1 %). Ekonomsko analizo shem smo opravili s programom Aspen Economic Analyzer. Najvišja investicija bi bila v procesno shemo z dvema destilacijskima kolonama (1,96 M€), najnižja investicija pa v procesno shemo na principu azeotropne destilacije, kjer je glavni kriterij ekonomska ugodnost sheme (0,763 M€). Ta shema ima tudi najnižjo dobo vračanja (0,11 a).

Title:Synthesis and simulation of process alternatives for separation of n-butanol from formaldehyde, methanol, isobutanol, n-butanol and water mixture
Abstract:This master's thesis discusses the preparation and study of various flow diagrams of separation alternatives for the separation of n-butanol from the mixture consisting of formaldehyde, methanol, isobutanol, and water, and their simulation was carried out using the Aspen Plus V10 software. Four different process flow diagrams were simulated. Three process flow diagrams were synthesised using the principle of consecutive distillation columns, while the fourth diagram was synthesised using the principle of azeotropic distillation. The fourth process flow diagram was simulated twice. In the case of the first simulation, the best possible separation efficiency was determined as the main criterion, while the economic feasibility was determined as the main criterion in the second simulation. The effect of operating parameters on the purity of n-butanol and on propellant consumption was studied. The results showed that the operating parameters, with the exception of the distillation residue flow in the studied areas, do not have a significant effect on the purity of the obtained n-butanol; however, they do have a significant effect on propellant consumption. Furthermore, thy synthesised flow diagrams were evaluated from an economic and a separation perspective. The highest process yield/efficiency and the best n-butanol purity were achieved with the simulation of a separation of said mixture using three consecutive distillation columns. The end product is n-butanol with a purity of w = 99.9% . The separation efficiency of said process flow diagram was 99.9%. The lowest process efficiency, provided that the basic process flow diagram with only one distillation column is not taken into consideration, was achieved with the simulation of a process flow diagram with two distillation columns (93.1%). The economic analysis of the flow diagrams was carried out using the Aspen Economic Analyzer software. The highest investment would be into a process flow diagram with two distillation columns (EUR 1.96 mil.), while the lowest investment would be into the process flow diagram made using the principle of azeotropic distillation, where the main criterion is the process flow diagram's economic feasibility (EUR 0.763 mil.). This flow diagram also has the lowest payback period (0.11 a).
