摘　　要：针对某航煤加氢装置现行换热网络夹点温差不合理导致能耗较大的现状,利用夹点技术对该装置换热网络进行分析、优化。在该装置实际工况下的夹点温差附近选取相应的夹点温差,计算出不同夹点温差对应换热网络的年总费用,得出年总费用最小的夹点温差,即最优夹点温差。在最优夹点温差的基础上生成新的换热网络,结果表明,节能效果显著。The pinch temperature difference of a heat exchanger network is unreasonable which can lead to more energy consumption.As a result,it must be considered seriously.This paper aims at the current situation of high energy consumption for a kerosene hydrofining unit.The pinch technology is used to analyse and optimize its heat exchanger network.Some temperature differences are selected according to the actual pinch temperature difference.The total annual cost is calculated for the temperature difference corresponding heat exchanger network.The minimum total annual cost corresponds to pinch temperature difference which is obtained through comparison.Then a new heat exchanger network is generated based on the optimal pinch temperature difference.Finally,it gains good energy conservation effect.
