Abstract: The dividing wall extractive distillation process for separation of ethyl formate/ethanol system with DMSO as extractive agent is simulated by means of Aspen Plus software.The sensitivity analysis tool is used to optimize the parameters affecting the separation effect.After the optimization,the mass fractions of ethyl formate and ethanol reaches 99.9% and 99.4%,respectively by dividing wall extractive distillation process.Compared with the traditional dual-column extractive distillation process,the dividing wall extractive distillation process can save energy by 6.7% and reduce the equipment investment when completing the same separation task.
