Combination of reactive and nonreactive sections in a RD column

Advantages (i) this approach can be applied to both fast and slow chemical equihb-rium reactions and ii) feasible products can be determined within a RD colmnn. 

Limitations (i) finding the reactive azeotropes might be sometimes troublesome and (ii) detailed knowledge of phase equilibrium, reaction kinetics and residence time within the column is required. 

Assumptions (i) binary system with a single chemical reaction (ii) CMO and (Hi) vapor-liquid equilibrium. 

McCabe-Thiele method. This method is used to assess qualitatively the impact of changing a design variable (Lee et al., 2000c). For the RD case, two main features are tracked to sketch the diagram for a binary mixture of reactants imdergoing an isomerization reaction and under CMO assumption, 

A simplified procedure for sketching the McCabe-Thiele diagram is depicted in figure 3.4 for an isomerization reaction.
