Resumen:
In this paper, a novel method to deal with the design and the synthesis of finishing reactive
distillation columns with one reactive core, two rectifying sections, and one stripping section is
presented. The attention of our work is concentrated on three subjects: (i) the feasibility of a
given separation at both finite and total reflux operation; (ii) the minimum energy demand
operation; (iii) the distribution of the reaction between the reactor and the finishing reactive
column. The design problem presents the same grade of difficulty as that found in the design
of conventional extractive columns. A geometric based method is used to explain key features
of reactive distillation. Here, the relation between the reaction yield and the distillate flow
rate plays a role similar to that of the entrainer flow in extractive distillation. Hence, special
attention is given to the behavior of the profiles inside the rectifying section below the reactive
core. The methodology is illustrated using the well-known MTBE case study.
