Revamping Fluid Catalytic Cracking Unit, and Optimizing Catalyst to Process Heavier Feeds

H-Oil gas oils have a higher density and nitrogen content, consequently much lower reactivity than straight-run vacuum during fluid catalytic cracking (FCC). The conversion of observed in laboratory unit at constant operating conditions showed 20 wt.% rate hydrotreated oil. Thus, revamp commercial FCC units, the selection activity catalyst with coke selectivity is needed to provide stable trouble-free operation unit. performed allowed throughput. It also an increased riser outlet temperature from 532 550 °C; maximum allowable regenerator 705 730 decreased afterburning 12 6 NOx emissions flue 250 160 mg/Nm3; improved regeneration; losses 0.0142 kg/t feed; circulation was confirmed that light oil least reactive cracking.
