Distillation Columns - Chemical Engineering

A reactive distillation column can replace a separate reactor and distillation column system. Reactive distillation columns have a reactive zone lined with catalyst bales, as shown in the schematic. These bales contain beads of catalyst resin to provide as much surface area as possible for the reactants. The two feed streams react in this zone.
