Bioethanol dehydration can be achieved in a highly-integrated process comprising of a dividing wall column, combining extractive distillation and vapour recompression technology. Compared to conventional processes, this integrated design allows 40% energy savings and reduces the energy requirements to only 4.45 MJ/kg ethanol. This work addresses the challenges related to process dynamics and control, which are just as important as the economic improvements. A dynamic simulation model, built in Aspen Plus Dynamics, is used to identify the control difficulties. Small design modifications are introduced to stabilize the system. A control structure is proposed, where the main element is temperature control of pre-fractionator side, achieved by a combined manipulation of the side reboiler external duty and recompressed vapour by-pass. Several concentration controllers ensure product quality. Dynamic simulations show that rather large feed flow rate and composition disturbances can be effectively rejected.
