FCC riser quick separation system a review SpringerLink
Oct 20 2016 · The riser reactor is the key unit in the fluid catalytic cracking (FCC) process. As the FCC feedstocks become heavier the product mixture of oil gas and catalysts must be separated immediately at the outlet of the riser to avoid excessive coking. The quick separation system is the core equipment in the FCC unit. China University of Petroleum (Beijing) has developed many kinds of separation
