Abstract.
Abstract - The multivessel batch column presented in this paper provides a generalization of previously proposed batch distillation schemes. The economic potential of the multivessel batch distillation under total reflux is demonstrated by comparing with a conventional batch distillation column. A simple feedback control strategy for total reflux operation of a multivessel column is proposed. The feasibility of this strategy is demonstrated by simulations.
