I am simulating a process for production of acetaldehyde by the dehydrogenation of ethanol.i need help on how to design the distillation columns. I counldnt find any information on the specs of the distillation columns
If you want to design the distillation columns, you must calculate first the stage numbers and the reflux ratio, hence, you have to use the DSTW tower at Aspen Plus. As entrance parameters you ought to specify the recovery of the light key (acetaldehyde) and heavy key (ethanol) in the distillate. After that, with the outcomes of the DSTW model (# stages, reflux ratio, distillate rate, feed stage), you can use this information to design the distillation in a rigorous way, through the RadFrac model at Aspen Plus.
