Feasibility of Batch Reactive Distillation with Equilibrium-Limited Consecutive Reactions in Rectifier, Stripper, or Middle-Vessel Column

Feasibility of Batch Extractive Distillation with Middle-boiling Entrainer in Rectifier

Feasibility of batch extractive distillation in rectifying column with a middle boiling entrainer is theoretically and experimentally studied. These processes are preferable when the entrainer is already present in the mixture to be separated. Separation of methyl acetate and cyclohexane (forming minimum boiling azeotrope) using carbon tetrachloride, and separation of chloroform and ethyl aceta...

Startup Operation of a Cyclic Middle Vessel Batch Distillation

Batch distillation is one of the most important unit operations for the small-scale production of specialty and fine chemicals. The so called Middle Vessel Batch Distillation (MVBD) with total reflux offers many advantages compared to conventional batch distillation. It is favourable due to the simultaneous production of three products of high purity. In this work, we present a thorough analysi...

Operation of a Batch Distillation Column with a Middle Vessel: Experimental Results for the Separation of Zeotropic and Azeotropic Mixtures

Batch distillation in a column with a middle vessel can avoid many of the disadvantages associated with the regular batch distillation processes. In this paper we present an experimental investigation of the separation of a zeotropic ternary mixture via total reflux operation and of the separation of an azeotropic binary mixture via batchwise extractive distillation. Moreover, the results obtai...

Multicomponent batch distillation column design

Simulation Of Reactive Distillation Column

Reactive distillation processes couple chemical reactions and physical separations into a single unit operation. The ethyl acetate production by esterification reaction is equilibrium limited and is suitable to be carried out in a distillation column. In the present work, a reactive distillation column for the production of ethyl acetate is simulated using Aspen Plus. The component compositions...
