Abstract
Methods for improving the operation of batch reactive distillation with off-cut are presented and discussed. Although off-cut can improve the operation of batch reactive distillation, its usefulness is limited in some cases due to the relative volatility ranking of reactants and products. In these cases, performance can be improved by using a middle vessel column or by using an excess of one reactant. These methods are demonstrated with case studies of three processes with realistic reaction kinetics and vapor-liquid equilibrium models: hydrolysis of methyl lactate, esterification of formic acid, and production of 1,1-dimethoxyethane. Batch capacity can be improved on average 41.9% if the appropriate method is employed. ? 2014 American Chemical Society.
