Simulation of biodiesel production through transesterification of vegetable oils / Scott Stiefel in Industrial & engineering chemistry research, Vol. 48 N°3 (Février 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N°3 (Février 2009) . - p. 1068–1071 Titre : Simulation of biodiesel production through transesterification of vegetable oils Type de document : texte imprimé Auteurs : Scott Stiefel, Auteur ; Gustavo Dassori, Auteur Année de publication : 2009 Article en page(s) : p. 1068–1071 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Bioenergy  Biodiesel  Vegetable  oils Résumé : Biodiesel can be produced from a number of natural, renewable sources, but vegetable oils are the main feedstocks. Most existing biodiesel plants currently rely upon the use of a homogeneous catalyst in a continuous reactor system, using the transesterification of soybean or rapeseed oil with methanol into alkyl esters. A key differentiation characteristic among the existing processes is that of the mixing pattern employed in the system. The present study compares reactor performances in terms of biodiesel yields for plug flow and complete mixing behaviors, along with the use of interstage phase separation. It is concluded that plug flow pattern shows a distinctive benefit in terms of yields and reactor volume reduction compared to complete mixing. Interstage separation improves the reacting system yields when proper phase separation can be achieved, maximizing glycerine removal from the downstream system. Staged mechanically stirred tank reactors can reach similar performances as plug flow behavior systems without resorting to interstage separation under the conditions here studied. Methanol/oil ratio can improve the reacting system performance and reduce differences, even if plug flow reactors are not employed.
