| Abstract: | This paper introduces the optimum design principle of heat transfer network by pinch technology, and presents one optimization design case to the Yan＇ an Refinery 3 million ton/year atmospheric distillation installment heat transfer network. The result is that logistics is matched more reasonably and heat transfer unit is reduced. After optimum design, 5 heat exchange units of heat transfer network are reduced compared with that of the original heat transfer network, thus equipments＇ investment is saved. |
