摘　　要： 介绍了一种以热进料为契机推动加氢装置全面优化的方法。采用三环节理论分别对塔、换热网络、加热炉和机泵进行系统优化,实现由热进料带来的低温热热量在装置内的升级利用,节约燃料和蒸汽。在中国石化某炼油厂1.0Mt/a柴油加氢精制装置中取得了装置能耗下降38.9%的显著效果。该方法也可用于其它下游装置的全面节能优化。 A method to promote the total system optimization of hydrotreating units by means of taking hot feed from upstream directly was introduced. Based on ＂Three-Link-Theory＂ energy structural model, by optimizing distillation towers, heat exchang network, furnace and compressors/pumps to realize upgrading the utilization of low grade heat from upstream hot feed, the fuel of furnace and the steam of reboiler were saved. From a case study of a 1.0 Mt/a diesel fuel hydrotreating unit in a SINOPEC refinery, it can be seen that a 38.9% reduction of energy consumption was obtained. This method could also be used to other downstream units for total optimization of energy conservation.
