  • Publication number: 20220403263
    Abstract: Described are a process and a system for processing aromatics-rich fraction oil. The process includes: (1) introducing an aromatics-rich fraction oil into a fifth reaction unit for hydrosaturation, followed by fractionation, to provide a first light component and a first heavy component; (2) introducing a deoiled asphalt and an aromatics-comprising stream including the first heavy component into a hydrogen dissolving unit to be mixed with hydrogen, and introducing the mixed material into a first reaction unit for a hydrogenation reaction; (3) fractionating a liquid-phase product from the first reaction unit to provide a second light component and a second heavy component; (41) introducing the second light component into a second reaction unit for reaction; and (42) introducing the second heavy component into a delayed coking unit for reaction; or using the second heavy component as a component of low sulfur ship fuel oil.

  • Publication number: 20220152534
    Abstract: The present invention provides an oil slurry filter, a filter unit including the oil slurry filter, a multiple-filter system including the oil slurry filter, and a multiple-stage filter system including the oil slurry filter. Due to the use of the filter component of flexible texture in the oil slurry filter of the present invention, the problems that the filter material is easily blocked by high-viscosity colloidal impurities, the regeneration efficiency of the filter is poor and the filtration efficiency is low are solved, and it is possible to make the backwash treatment of the filter residue more convenient and improve the regeneration efficiency of the filter. The present invention also provides a filtering process using the oil slurry filter to ensure long-term stable operation of the oil slurry filtering process.
