山东胜利炼油厂原设计为120万吨/年的催化裂化装置,在这次技改中拆除了原用的U形管反再系统,采用了提升管反应器和烧焦罐高效再生催化剂新工艺,使加工能力提高到140万吨/年,成为我国最大的一套催化裂化装置,一天即可创利税80万元。1990年11月2日一次开车成功,即证明这次改造是成功的,并使该装置具有弹性大、操作灵活、轻油收率高和催化剂损耗低等特点。不但为企业增收上千万元,且可为国内同类装置的改造提供了有益经验。
Shandong Shengli Refinery was originally designed to produce 1.2 million tons of FCC units. The original U-tube anti-re-system was removed in this technical innovation. A new process of high-efficiency regenerated catalyst for riser reactor and scorch tank was adopted , So that processing capacity increased to 1.4 million tons / year, becoming China’s largest set of catalytic cracking unit, a day you can create profits 800,000 yuan. A successful drive on November 2, 1990 proved that the retrofit was successful and made the unit resilient, flexible, with high light oil yield and low catalyst loss. Not only for the business to increase tens of millions of dollars, and for the transformation of similar devices provided a useful experience.
