一、前言我厂加氢生成油再蒸馏的工艺原是五十年代的水平其工艺流程为加氢生成油降压后,经碱洗、水洗,进入中间罐,然后蒸馏再抽出加工。这种工艺流程不仅是把加氢和蒸馏分开,中间还增加了一套碱洗装置,且生成油进入中间罐,使大量溶解于生成油中的瓦斯也都白白地散发掉。瓦斯的跑损,碱渣的污染给环境保护和能源的利用都带来严重的影响,尤其是我厂加氢四套采用蜡油加氢降凝工艺,含溶解气 First, the foreword I plant hydrogenation of oil and then distillation of the original process is the level of the fifties The process for the hydrogenation of oil after step-down, caustic washing, washing, into the middle tank, and then distillation processing. This process not only separates hydrogenation and distillation, but also adds a caustic washing unit to the middle and generates oil into the intermediate tank, allowing large amounts of gas dissolved in the oil to be generated. Gas running loss, alkali residue pollution to the environmental protection and energy use have a serious impact, in particular, I plant four sets of hydrogenation using wax wax hydrogenation process, including dissolved gas
