Reactive DWC leading the way to FAME and fortune

► FAME synthesis by esterification of free fatty acids (FFAs). ► Reactive distillation in a dividing wall column (DWC). ► Eco-efficient solid catalysts in high efficient equipment. ► Energy savings of 25% by optimal column design using simulated annealing. ► Rigorous simulations performed in AspenTech Aspen Plus linked to Matlab.
