Abstract: The form of rich amine with hydrocarbons and oils entrained is microbubbles, easily gasified light hydrocarbons and liquid oils. Centrifugal flash technology is used to quickly separate the microbubbles and light hydrocarbons, and fiber oil removal technology is used to deeply capture and separate the liquid oil droplets. This combined technology was implemented in a 1.4 Mt/a hydrocracking unit. The light hydrocarbons and condensed oil in the rich amine were recycled, the flashing gas volume of the flash tanks in downstream solvent regeneration unit was reduced by over 95% compared with the gas volume before modification, and the desulfurization solvent loss was reduced, meeting the current economic and environmental protection requirements of the desulfurization system in inferior crude oil processing

Key words: rich amine regeneration, centrifugal flash, fiber oil removal, hydrocarbon and oil recovery, non-thermal separation
