Abstract
The design and operation issues for reactive distillation systems are considerably plex than those involved for either
conventional reactors or conventional distillation columns. The introduction of an in situ separation function within the reaction zone
leads plex interactions between vapor}liquid equilibrium, vapor}liquid mass transfer, intra-catalyst di!usion (for heterogen-
eously catalysed processes) and chemical ics. Such interactions have been shown to lead to the phenomenon of multiple
steady-states plex dynamics, which have been veri"ed in experimental laboratory and pilot plant units. We trace the
development of models that have been used for design of reactive distillation columns and suggest future research directions. ( 2000
