A novel biodiesel process is proposed based on a reactive dividing-wall column (RDWC) that allows the use of only ∼ 15% excess of methanol to completely convert the fatty acids feedstock. Fatty acid methyl esters were produced as pure bottom product, water as side stream, while excess methanol is recovered as top distillate and recycled. A significant energy savings of ≥ 25% can be achieved by applying the simulated annealing optimization. The integrated RDWC alternative have several key benefits as compared to conventional processes. This is an abstract of a paper presented at the CHISA 2012 - 20th International Congress of Chemical and Process Engineering and PRES 2012 - 15th Conference PRES (Prague, Czech Republic 8/25-29/2012).
