Progress of Energy-saving Optimization of Distillation Column

The energy consuming of the operation process of distillation column was analyzed,and the measures of energy-saving and consuming optimization were put forward.Combined to the process of fractionating tower to the thermodynamics efficiency of need,the fractionating tower of energy and efficiently separate technique and the separation of fractionating tower-film and the fractionating tower-absorption mixture system etc.were analyzed and its gains or losses were elaborated in detail.Meanwhile,the prospect for energy-saving measures was outlined.
