A review: control of reactive divided wall distillation column

IntroductionDistillation the widely used separation technique in chemical industries but the problems in convention separation techniques are high energy requirements, large carbon footprint and high investment costs, operating and maintenance cost.Reactive distillation is combination of reaction and separation process in single column reactions that cannot be completed without separation of one product, are called equilibrium limited reactions.Such reactions are called 'equilibrium limited' reactions such as esterification, ester hydrolysis and transesterification; these reactions can be accomplished in reactive distillation column.This offers distinct advantages over the conventional sequential approach.In distillation the principal objective, is separation which is normally measured by the product purity.The modelling of RD column is difficult task due to reaction and separation in the same column.The process of RD was first patented in 1920 and was commercialized on 1980s since Eastman Company owned and run a commercial process for the production of methyl acetate.
