Studies on the Strategy of Graphical Design for Reactive Distillation System

On basis of the theoretical study of graphical design of reactive distillation system, the applied area and limitation of reaction space, transformed composition variables and residue curves were discussed. By analyzing the change of the equation of operation lines in reactive distillation, some strategies for the design of reactive distillation processes were gained. Firstly, the feasibility of a reactive distillation can be gotten by using the singular points and data from experiments. Secondly, it can by decided if a system can be separated completely in a column in terms of the concept of reaction space. Last, the results can be gotten by using the graphical design and corresponding strategies were proposed. The feasibility of these strategies was validated through some examples.
