Intensification of reaction and V-L separation in batch systems

Abstract

This article addresses the feasibility requirement for producing pure products when intensifying reaction and V-L separation in batch systems. With one unstable node (UN) product in a residue curve map that is reachable from all distillation regions or a part of reaction equilibrium manifolds, a batch rectifier can produce pure products. The symmetric result is conserved for a batch stripper with one stable node (SN) product. With the UN and SN products that share a distillation region with a reaction equilibrium manifold, a middle vessel column (MVC) is feasible to produce those pure products. With all saddle (S) products, a batch reactive extractive (BRED) column can be used to produce pure products. In this case, we should use a suitable entrainer.
