Abstract
Disclosed is a process and apparatus for recycling flue gas from a regenerator back to the regenerator to provide fluidization gas needs. Catalyst may be separated from the flue gas before recycle and the flue gas may be compressed before recycle to the regenerator. The process and apparatus reduces the size capacity of downstream product recovery equipment by reducing gases derived by oxidation in the process and reduces the potential for after burn in the regenerator.
Claims20
A process for regenerating catalyst comprising:
- combusting coke from spent catalyst in a regenerator to provide regenerated catalyst and flue gas;
- discharging flue gas from said regenerator;
- separating catalyst from said flue gas discharged from said regenerator;
- and
- recycling said flue gas to said regenerator.

A process for regenerating catalyst comprising:
- combusting coke from spent catalyst in a regenerator of an FCC unit to provide regenerated catalyst and flue gas;
- contacting said regenerated catalyst with hydrocarbon feed in said FCC unit to provide cracked products and spent catalyst;
- discharging flue gas from said regenerator;
- separating regenerated catalyst from said flue gas discharged from said regenerator;
- and
- compressing said flue gas.
