Abstract: According to the prehydrogenation and predistillation of catalytic reforming unit, this article utilize the pinch technology to analyze, find the energy bottleneck, simulate and optimize the whole heat exchange network by Aspen energy analyzer, compared with original heat exchange network , energy saving 3 735 kW (23.5%). Aiming at reduce the amount of utility and raising the profit for the enterprise.

Key words: Catalytic reforming, Heat exchange network, Aspen plus, Pinch technology, Optimizing

摘要： 利用夹点技术, 通过 A s p e ne n e r g ya n a l y z e r , 对抚顺石化公司石油三厂催化重整装置中预加氢段和预
分馏段的换热网络进行了能量分析, 找出了用能瓶颈, 并优化设计换热网络。优化后, 预加氢和预分馏段的公用工
程降低37 5 7kW, 节能2 3. 5%, 达到了降低公用工程用量、 增加经济效益的目的。
