RFCC Units Set New Standards for Contaminated Resid

摘要

In the past few years, several RFCC units have been commissioned and operated to convert resid to high levels of propylene utilizing UOP's Resid FCC Process Technology. Included among this class are units which process hydrotreated resid as well as straight run resid. Processing heavily contaminated resid using UOP Combustor Regenerators with catalyst coolers is gaining wider acceptance alongside two stage regenerators with catalyst coolers. Catalyst coolers expand the flexibility of these units to process heavily contaminated resid feedstocks, enabling high conversion levels and high propylene production rates.
