Abstract

Acetonitrile is one of the important organic solvent which widely used in the industrial application. The high purity of acetonitrile can be obtained with the extractive distillation process to separate acetonitrile from water by using an entrainer. The acetonitrile-water extractive distillation using ethylene glycol as an entrainer was investigated using Aspen Plus. The RadFrac module distillation followed by ethylene glycol recovery column was utilised in the simulation. The phase equilibrium calculation of the mixture was calculated using The Non-Random Two Liquids-Hayden-O'Connell (NRTL-HOC) thermodynamic model. The effects of reflux ratio, number of stages, binary and entrainer feed stage, feed temperature on the distillate composition and energy consumption were discussed. The results show that the optimum parameters design consists of the theoretical stages of 45, the binary feed stage of 27, entrainer feed stage of 15, the binary feed temperature of 62 oC, and the reflux ratio of 0.6 were required to achieve the purity of acetonitrile higher than 99 %w.
