UOP工艺技术在3.5Mt/a重油催化裂化装置的工业应用

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2.80μg/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2 372.66 MJ/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。

Commercial application of UOP' s process in a 3.5 MM TPY RFCC unit

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 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.
