| Abstract: | The fundamental step of optium disigning of chemical heat exchange network by pinch point method has been introduced.In the same time,the basic rules of matching hot and cold streams,the method of calculating the minimum number of equipment for the exchange network and the trade-off between the energy recovery and the units cost have been discussed.At last,The method has been applied practically in the design of the north distillation exchange network ofFushun refinery No.3,and turned out to be instructive for the inovation and energy saving of the network. |
