Abstract: Revamping with MIP technology, the capacity of the RFCCU in Jinxi Petrochemical Company was expanded from 1 400 kt/a to 1 867 kt/a, and reached 1 932 kt/a in maximum. The performance test results showed that the ratios of VR and CGO in the mixed feedstock could be increased to 28.5w% and 25.3w%, respectively, so that extra 400 kt of heavy oil could be processed per year. The olefin content in the cracked naphtha was reduced by 13.4 percentage points due to the effective olefin reduction function of MIP technology. The product slates well met the design target, and the total liquid yield (73.46%) was 2.96 percentage points higher than the design value. A 17.19 million RMB economic benefit was obtained annually.
