ABSTRACT:
Disclosed is an apparatus for combusting dry gas to heat the air fed to an FCC regenerator to increase its temperature and minimize production of undesirable combustion products. Preferably, the dry gas is a selected FCC product gas. Alternatively or additionally, dry gas from an FCC product stream is separated and delivered to an expander to recover power before combustion.
