摘要
在夹点技术的基础上,结合工艺流程模拟软件(HYSYS)和换热网络计算软件(HEX-TRAN)对原有常减压装置换热网络进行优化,并得出了近于最优的换热网络。优化后的换热网络经实际生产运行取得了良好的效果和可观的经济效益。
On the basis of the pinch technology,The old heat exchanger network was optimized to get the best heat exchanger network by the process flows simulated software （HYSYS）and heat exchanger network simulated software（HEXTRAN）.The new optimized heat exchanger network got satisfied operating result and considerable economic profits.
