China is a big industrial energy consuming country.The largest proportion of energy consuming is the operations of separation in chemical industry,and the energy consumption of the distillation is the highest in separation.Therefore,it is very important to research energy-saving issues of the process of distillation in todays circumstances of the energy shortage.This article describes the model of closed heat pump distillation column,and its characteristics,uses static simulation programs to simulate operating conditions in the atmospheric pressure for the benzene-toluene material system,and studys effects of the different feed state on the energy-saving of closed heat pump distillation column.The results will be compared with the conventional distillation colunm,and it was showed that for benzene-toluene system,the closed heat pump distillation column is more remarkable than the conventional distillation column in energy savings,and its energy saving rate canreach 46%.
