Energy efficient distillation

The Technical and Energetic Challenges of Separating (Photo)Electrochemical Carbon Dioxide Reduction Products

“…While some of this heat can typically be recovered, Halvorsen and Skogestad (2011) found that the required energy input for conventional distillation can be more than 50% higher than the theoretical thermodynamic minimum, and often much higher. We will not provide a detailed analysis of distillation processes here, as comprehensive references can be found elsewhere (e.g., McCabe et al, 2001;Green et al, 2007), but instead provide perspective on the energetic expense of distillation relative to the energy available from products of P/EC systems.…”

Optimal Operation and Control of Four-Product Dividing-Wall (Kaibel) Distillation Column

“…Because a four product divided wall distillation column (kaibel) have 9 dynamic degree of freedom (feed rate, distillate rate, bottom rate, side draw-1, side draw-2, reflux rate, liquid split, vapor split, vapor flow rate and condenser duty) for stabilizing the control of divided wall distillation column [19].…”
