Novel procedure for coproduction of ethyl acetate and n - butyl acetate by reactive distillation / Hui Tian in Industrial & engineering chemistry research, Vol. 51 N° 15 (Avril 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 15 (Avril 2012) . - pp. 5535–5541 Titre : Novel procedure for coproduction of ethyl acetate and n - butyl acetate by reactive distillation Type de document : texte imprimé Auteurs : Hui Tian, Auteur ; Huidong Zheng, Auteur ; Zhixian Huang, Auteur Année de publication : 2012 Article en page(s) : pp. 5535–5541 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Reactive  distillation  Ethyl  Acetate Résumé : A novel energy saving procedure for the coproduction of ethyl acetate and n-butyl acetate by reactive distillation is simulated by Aspen Plus in this paper. Its feasibility is theoretically analyzed on the basis of the physical properties of ethyl acetate/n-butyl acetate system. The new procedure not only significantly reduces energy consumption, but also eliminates the acetic acid purification column, as compared with the individual processes. The outputs of ethyl acetate and n-butyl acetate can be adjusted flexibly by changing the feed molar ratio of ethanol to n-butanol in a certain range. When the feed molar ratio is less than 1.0, the purity of the products is the same as that for those obtained from the individual procedures. Also, energy-saving increases as the feed molar ratio of ethanol to n-butanol decreases. When the feed molar ratio of ethanol to n-butanol is 0.5, 20.40% energy-saving is achieved, as compared with the individual procedures. At last, the total annual cost (TAC) of the individual and coproduction procedure is calculated, and the TAC of the coproduction is 3 795 912 USD/Y (U.S. dollars per year) less than the individual’s 5 190 921 USD/Y, when 10 000 t EtAc and 26 363 t n-BuAc are produced.
