The Analysis and Comparison of the Heat Pump Distillation and the Multi-effect Distillation

In the chemical industry,the distillation process is one of the largest energy consumption of unit operation.In order to reduce the energy consumption of distillation,by changing the traditional process,some new technologies were imported in which the heat pump distillation and the multi-effect distillation are widely applied.The paper introduced the heat pump distillation and the multi-effect distillation theory,as well as their application in the industry,comparison and analysis of two.
