| Abstract: | The heat exchanger network (HEN) of Atmosphere-Vacuum Plant in Oil Refinery of JCGC is studied on the energy saving using our software package of the HEN. The problems of the old HEN are found out. A retrofitted HEN is proposed by means of the synthesis, analysis, and simulation of HEN and optimum design of heat exchangers. The end temperature of bottom oil of the primary tower in the heat exchanger is risen from 302℃ to 322℃. The technological remolding was done in the May 2000, and technical standardization was done in the June 2000. The designed indexes are reached. Fuel oil of 4914 tons per year is saved. Benefit is 6.88 million yuan/a. The investment is 1.5 million yuan. The return time of the investment is 2.6 months. WT5HZ] |
