UOP工艺技术在3.5Mt/a重油催化裂化装置的工业应用

摘要

中国石油广西石化分公司3.5 Mt/a重油催化裂化装置为国内近来唯一一套整体引进UOP工艺技术的装置,采用代表世界先进技术水平的两段再生器、VSSSM快分、高效AFTM环形档板汽提、全密相流外取热器等先进技术.通过一年的正常生产和标定,在原料比重为0.93、残炭为7.41％、重金属Ni,V质量分数分别为15.30μg/g和2.80 μg/g的情况下,干气质量收率为3.07％、液化气质量收率为17.17％、汽油质量收率为39.42％、柴油质量收率为22.95％、油浆质量收率为7.17％、焦炭收率为9.91％,催化剂单耗为1.41 kg/t,单位能耗为2 372.66MJ/t,表现出优良的重油转换能力和产品选择性能,在产品分布和能耗方面达到国内先进水平.%The 3. 5 MM TPY RFCC in PetroChina Guangxi Petrochemical Company is the only RFCC unit with process licensed from UOP in recent years, which applies the state-of-the-art two-stage regenerator, VSS separator, high-efficiency AFTM stripper and once-through catalyst cooler. After one year's normal operation and performance testing, unit' s product slate has shown that the dry gas make is 3. 07% , LPG yield 17.17% , gasoline yield is 39.42% , diesel yield 22.95% , slurry oil 7. 17% , the coke make 9.19% , catalyst consumption 1.41 kg/t feed and energy requirement 2 372.66 MJ/t under the conditions of the feedstock properties of S. G 0. 93, CCR 7. 41% , Ni 15. 30 μg/g and V 2. 80 μg/g. All these demonstrate that the RFCC unit has an excellent bottom upgrading capability and good product selectivity. It is at the leading edge in product distribution and energy consumption.
