中国石化镇海炼化分公司300万吨/年柴油加氢装置设计生产硫含量小于0.05%的国Ⅳ车用柴油,后经更换第一反应器换催化剂、增加一台第二反应器及调整原料和操作条件,可用于生产国V柴油。由于装置生产方案的调整,装置能耗有所增加,同时脱硫化氢汽提塔塔顶气和产品分馏塔塔顶气量均大幅度增加,导致后路空冷器电耗加大,为达到节能减排的目标,在塔顶增加板式换热器,以达到减少空冷器耗电量和能量合理利用的目的。

The country IV diesel with sulfur content less than 0. 05% is produced by diesel hydrogenation unit of 3 million tons/year in Sinopec Zhenhai Refining and Chemical Division. By the replacement of the first reactor for catalyst, increasing a second reactor, the feedstock and operating conditions, the unit can also produces the country V diesel. Due to the adjustment of the production scheme of the device, the device energy consumption increased, simultaneous removal of H2 S stripping tower top gas and product fractionator top volume increased, as the result power consumption in posterior air coolers increased. In order to achieve the goal of energy saving and emission reduction, the heat exchanger at the top of the tower was increased to reach the goal of reducing air cooler power consumption and energy utilization.
