Resumen:
Some aspects related to the design of reactive distillation columns with a reacting core are
addressed in this paper. A set of transformed composition variables proposed in a previous
paper is used to develop both the design equations and the reactive residue curve maps for
quaternary reacting mixtures. Also, conventional residue curve maps are employed to achieve
a better physical and conceptual insight into the relationships between the different constitutive
parts of a column with a reacting core. Limitations in product specifications of entirely reactive
distillation columns are explained by means of reactive residue curve maps, and a new feasibility
criterion of a given separation for reactive columns with a reacting core is also developed on the
basis of the two extreme operation conditions of a column. Finally, the behavior of column profiles
for both high-conversion and low-conversion cases is analyzed and optimal product specifications
are suggested to obtain high purity products. As we concluded in previous works, the inerts
have a central role in both the design and synthesis of a reactive distillation column. All the
concepts are applied to azeotrope-forming mixtures.
