Simulation and model-validation of batch distillation processes in Aspen Batch Modeler: Limonene epoxide distillation

Abstract

Modeling and simulation of a Batch distillation column was developed for the recovery of limonene epoxide from a multicomponent mixture using advanced software Aspen Batch Modeler. For model validation, an experimental setup was developed using rotary evaporation equipment, and varying parameters such as initial composition of the mixture, temperature and pressure. The mixture composition in bottoms and distillate was determined by gas chromatography. The results indicate that the proposed models describe satisfactorily the simulated phenomenon and allow to predict with acceptable accuracy (RMSD ? 0.087) the final composition of the mixtures; hence representing a useful tool to study and analyze the conceptual design, optimization and/or scaled-up for the process. In addition, the model development is presented in detail, so it can be used as reference material for the simulation of similar processes or academic purposes.
