该装置于1996年4月28成功投产。加工的原料油为减压渣油、减压蜡油和焦化蜡油,最大掺渣量达40％.装置的主要技术特点有:①采用高温短接触超稳分子筛提升管,并注入金属钝化剂以抑制催化剂上重金属脱氢反应和生焦;②采用两段再生新工艺,配有烟气能量回收系统和外取热器,催化剂回收采用了高效旋风分离器,并采用了灵活调节催化剂循环量的分装式电液驱动冷壁滑阀;③采用集散控制系统;④取消了开工加热炉,节省
The unit was successfully put into operation on April 28, 1996. The processing of raw materials for the vacuum residue, vacuum oil and coker gas oil wax, the maximum dregs up to 40%. The main technical features of the device are: ① high temperature short-contact ultra-stable molecular sieve riser, and into the metal passivation Agent to restrain the heavy metal dehydrogenation reaction and coke formation on the catalyst; (2) a two-stage regeneration process is adopted, equipped with a flue gas energy recovery system and a heat extractor, an efficient cyclone separator is adopted for the catalyst recovery, and the catalyst circulation is adjusted flexibly Volume sub-type electro-hydraulic drive cold-wall slide valve; ③ using distributed control system; ④ canceled the start furnace, saving
