沧州炼化原柴油加氢装置汽提塔是以蒸汽为介质,致使柴油含水量较高。又因其装置规模小,能力不足,造成直馏柴油通过碱洗进罐后,只能反复地对其沉降、脱水和化验,放置几天后,才能使柴油含水量达到质量指标。同时,柴油产品质量需要化验人员十几次反复爬罐采样、分析,每次需要2小时以上。储存过程中还需要反复实施脱水、倒罐和循环,浪费大量的人力物力。为了确保产品质量,沧州
Cangzhou refinery original diesel hydrogenation unit stripper steam as a medium, resulting in higher water content of diesel. Because of its small size, lack of capacity, resulting straight-run diesel through caustic washing into the tank, it can only be repeated on its settlement, dehydration and laboratory tests, place a few days before the moisture content of diesel to achieve quality indicators. At the same time, the quality of diesel oil products need more than a dozen times repeatedly crawling tank sampling, analysis, each need more than 2 hours. Storage process also need repeated implementation of dehydration, pouring and recycling, wasting a lot of manpower and resources. In order to ensure product quality, Cangzhou
