Abstract:
The present invention relates to a combustion device for meeting the energy demand of processes for producing light olefins (ethylene and propene) in fluidized-bed catalytic cracking units. Said combustion device is used to burn heating oil and to keep burning the coke deposited on the catalyst, with a view to heating it to meet the energy demand of the reaction, combustion taking place smoothly and uniformly, preventing the formation of hotspots within the catalytic bed and in the dilute phase following combustion (afterburning), thereby minimizing deactivation of the catalyst and the risk of damage to the equipment inside of the combustion device.
