Abstract

reactive distillation is the combination of separation and reaction ina single vessel. Today reactive distillation is discussed as a part of the broader area of reaction and separation, which comprises of many combination of chemical reaction with separation methods including distillation, stripping, absorption, extraction, crystallization and membrane separation.

reactive distillation is a unit operation in witch chemical reaction and distillation separation are carried out simultaneously with a fractional distillation apparatus. Conversion can be increased far beyond chemical equilibrium conversion due to the continuous removal of reaction products from the reactive zone. This may lead to enormous reduction of capital and investment costs and may be important for suitable development due to lower consumption of resources. Enhancement in conversion, selectivity, energy utilization, reductions in equipment cost are some of the objectives simultaneously fulfill by reactive distillation. It has become an attractive technology not only for reaction engineers but also for separation technologists. Because of the advance in reaction engineering, catalysis, modeling and simulation, reactive distillation has been able to advantageously accommodate several reactions under its umbrella. New applications are being explored with an increasing rate. reactive distillation has started looking beyond the classic of esterification, etherification reaction. It can be successfully used for both fine and bulk chemicals.
