Abstract

The invention provides a slurry-bed hydrocracking high pressure hot separator with cyclone separators, which comprises a housing, wherein the housing is in an upper end and lower end closed cylindrical shape; the housing is externally provided with a reaction product inlet (11) used for injecting a slurry-bed reaction product into the housing, and is further externally provided with a high pressure hot separator gas outlet (12) used for exhausting high pressure hot separator gas in the housing; a high pressure hot separator liquid outlet (13) used for discharging high pressure hot separator liquid in the housing is arranged at the lower part of the housing; and the two cyclone separators are sequentially connected between the reaction product inlet (11) and the high pressure hot separator gas outlet (12), and arranged in the housing. The two cyclone separators are arranged in the slurry-bed hydrocracking high pressure hot separator with the cyclone separators, so that the separating effect of solid is improved.

Description

technical field [0001] The invention relates to the field of petrochemical and coal chemical equipment, in particular to a thermal high-pressure separator with a suspension bed hydrogenation with spin separation. Background technique [0002] The suspended bed hydrogenation reactor processes heavy oil (coal tar, atmospheric residue, vacuum residue, catalytic oil slurry, fuel oil, etc.) and a mixture of heavy oil and coal powder (oil-coal Slurry), and the hot high-pressure separator with suspended bed hydrogenation (referred to as hot high fraction) is used to separate the gas phase and liquid-solid phase of the suspended bed reaction product, so that the unconverted residual oil and solid additives enter At the bottom of the thermal high fraction, the separated gas phase product enters the second-stage suspended bed thermal high fraction from the top of the thermal high fraction for further separation. Finally, the gas phase product of the suspended bed from which the solids...
