摘要：

The existing heat exchanger network (HEN) at a refinery is analysed and redesigned by grassroots as well as retrofit designs. The integration of heat pumps into the network is also investigated. The results indicate that the existing network consumes approximately 6% more energy than the optimum design. Retrofitting the existing network leads to a design similar to the optimal grassroots design. To achieve the energy saving, the heat exchanger area has to be increased by 9%. The estimated payback is 1.5 years if a large fraction of the existing heat exchanger area is reused. The effect of heat pump installations is considered and some alternative cases are presented. Significant energy savings could be achieved but the economics is open to discussion. © 1990.
