Performance assessment by simulation of a gas-recycle oxosynthesis plant with propylene Recovery / Emil-Florin Tuţa in Industrial & engineering chemistry research, Vol. 50 N° 8 (Avril 2011) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 50 N° 8 (Avril 2011) . - pp. 4545–4552 Titre : Performance assessment by simulation of a gas-recycle oxosynthesis plant with propylene Recovery Type de document : texte imprimé Auteurs : Emil-Florin Tuţa, Auteur ; Grigore Bozga, Auteur Année de publication : 2011 Article en page(s) : pp. 4545–4552 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Gas  Propylène Résumé : A simulation study of a C4 oxosynthesis plant (gas recycle technology) was performed by using the software package Hysys. The process thermodynamics was described by UNIQUAC property model. An important drawback of this technology is a significant loss of propylene by the purge gas stream. Computer simulations were carried out to evaluate the technical performance and the investment cost of a proposed revamping scheme, allowing an advanced propylene recovery from purge gases. The cost evaluations performed with Aspen Economic Evaluation are indicating that the revamping investment cost is equivalent to the propylene savings during a three years plant running period.
