| Abstract: | In this paper, the energy saving and optimal operation policy has been proposed for solvent recovery system of the ketone-benzene dewaxing process . It is to find the limit (or called global optimization solution) of using energy based on the pinch technology, integrate the retrofit heat exchanger network and to optimize operation conditions. The network created by using the policy is very close to global optimization solution and has made a large energy saving in refinery. |
