Residual Fluid Catalytic Cracking Process by KBR and ExxonMobil
Conversion of low-value residual feeds and deasphalted oils from heavy crudes to high-valued light olefins, gasoline and distillates.
The converter is a one-piece modularized unit that efficiently combines KBR’s proven Orthoflow features with ExxonMobil’s advanced reaction design features. The regenerator is a single vessel that operates in partial or complete CO combustion with a dense phase catalyst cooler depending on the coke-forming tendencies of the feedstock.
The regenerator operates with a counter current flow of air and catalyst featuring a (1) spent catalyst distributor that evenly distributes the catalyst over the regenerator bed; and a (2) proprietary baffle that limits back-mixing between the upper and lower portions of the bed, effectively achieving a staged combustion in a single regenerator. The counter-current regeneration also reduces NOx emissions compared to other types of regenerators.
