Demonstration plant for new FCC technology yields increased propylene

A novel FCC process that boosts propylene production has been proven in a 30-b/d demonstration plant in Saudi Arabia (Fig. 1). Suitable for an integrated refinery-petrochemical complex, the high-severity process combines mechanical modifications to conventional FCC with changes in process variables and catalyst formulations. This 30-b/d demonstration plant in Saudi Arabia shows that a new high-severity FCC process yields more propylene than conventional processes (Fig. 1)Click here to enlarge imageThe process’ main operating features are a downflow reactor system, high reaction temperature, short contact time, and high catalyst:oil ratio. Similar to most reactor designs involving c...
