Modeling, Simulation and Control of Middle Vessel Batch Distillation Column

Simulation and Control of an Aromatic Distillation Column

In general, the objective of distillation control is to maintain the desired products quality. In this paper, the performances of different one point control strategies for an aromatic distillation column have been compared through dynamic simulation. These methods are: a) Composition control using measured composition directly. This method sufferes from large sampling delay of measuring de...

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...
