【摘要】：介绍了渣油加氢-催化裂化(RICP)双向组合技术在中国石油四川石化公司催化裂化装置的工业应用情况,探讨了RICP组合技术中催化裂化装置工艺操作调整措施。在RICP组合技术中,将减压渣油与催化裂化重循环油作为渣油加氢原料,经加氢处理后送至催化裂化装置。结果表明:RICP组合技术改善了催化裂化进料性质,催化裂化原料油残炭减小0.47百分点,氢含量增加0.3百分点,饱和烃质量分数增加4.26百分点,胶质和沥青质含量明显减少;改善了催化裂化产品分布和产品性质,催化裂化总转化率提高0.67百分点,总液体收率提高1.42百分点,焦炭产率下降0.63百分点,油浆产率下降0.85百分点,柴油十六烷值有所提高。
[Abstract]:This paper introduces the industrial application of residue hydro-catalytic cracking (RICP) bidirectional combination technology in the FCC unit of Sichuan Petrochemical Company of PetroChina, and probes into the operation adjustment measures of the FCC unit in the RICP combination technology. Vacuum residuum and FCC heavy circulation oil were used as feedstock for residue hydrogenation in RICP combination technology, and then sent to FCC unit after hydrogenation. The results showed that the performance of FCC feedstock was improved by using the technology of: 1% RICP, the carbon residue of FCC feedstock decreased by 0.47%, the content of hydrogen increased by 0.3%, the mass fraction of saturated hydrocarbon increased by 4.26%, and the content of colloid and asphaltene decreased obviously. The distribution and properties of FCC products were improved. The total conversion rate of FCC was increased by 0.67%, the total liquid yield by 1.42%, the coke yield by 0.63%, the slurry yield by 0.85%, and the cetane number of diesel oil by 0.85%.
