| 摘 要： | 基于某润滑油加氢装置现行的换热网络,利用夹点技术对其进行分析改造,得到了较好的节能效果。以系统总费用最小为目标,求得最优夹点温差为20℃;以夹点温差为20℃,计算得出该装置换热网络的夹点平均温度为186.9℃,最小热公用工程量为2995 kW,最小冷公用工程量为7755 kW;针对换热网络不合理的情况提出了优化改造方案,该方案可实现节约热公用工程2881 kW,占现行热共用工程的43.0%,节约冷公用工程2881 kW,占现行冷公用工程的25.1%,节能效果显著。

| Abstract: | A good effect was obtained in energy saving by analyzing and retrofitting the present heat exchanger network(HEN) of a lube oil hydro-treating unit using the pinch technology.Take the minimum total cost of the system as the target,an optimum pinch temperature difference(PTD) was calculated,which was 20℃.With pinch temperature difference 20℃,the average pinch temperature of the heat exchanger network was 186.9℃,the minimal requirement of the hot utility and the minimal requirement of the cold utility were 2995 kW and 7755 kW,respectively.Considering the improper matches of the HEN,a retrofit scheme was proposed which can save 2881 kW hot utilities and 2881 kW cold utilities,i.e.the scheme can save the hot and cold utilities by 43.0%and 25.1%,respectively. |
