title = "Dynamics and control of a heat pump assisted azeotropic dividing-wall column (HP-A-DWC) for biobutanol purification",
abstract = "Recently, the butanol purification from acetone-butanol-ethanol mixture was achieved in one azeotropic dividing-wall column requiring 2.7 MJ/kg butanol, which represents just 7.5% of the energy content of butanol. Compared to a conventional separation sequence, this design allows 60% energy savings due to heat integration and use of a heat pump. This work considers the dynamics and control of the process. The basic regulatory control can provide stability for small and short-time disturbances, but the process shuts down if the disturbances persist. By adding a reboiler and a condenser, better control becomes possible. As a result, the process can handle large and persistent disturbances in feed rate and composition, achieving good control of product purity.",
