A systematic methodology based on residue curve maps for the design of batch distillation processes Chapter uri icon


  • A computer-aided systematic methodology, based on residue curve maps (RCM) analysis, for batch distillation process design, mainly used in the fine chemicals industry, is presented and applied. Such methodology consists of generating and evaluating a plethora of possible operation options in order to identify the optimal operation conditions, either for the design of a new process or the improvement of an existing one. The options are generated based on the type of mixture: azeotropic or non- azeotropic; distiller type: direct (rectifier), reverse (stripper) or intermediate tank column (middle vessel); and operating policy. A particular case of the perfume industry is discussed to describe the application of the methodology, which is the distillation of a ternary mixture toluene - dichloromethylbenzene - chloromethylbenzene which is widely used in the perfume industry. As a result, the operation policy that allowed the maximization of the recovery of compounds, with high purity, was determined. © 2014 Elsevier B.V.
