Abstract:
The present invention is related to an integrated process for enhancing the yields of propylene and other light olefins from Fluid catalytic cracking (FCC) process in combination with Oxidative propane dehydrogenation (OPDH) where in a hydrocarbon stream from Propylene recovery section consisting of propane predominantly, is converted to high value light olefins primarily C 3  and C 2  olefins by catalytic oxidative dehydrogenation using carbon dioxide from FCC flue gas exiting the regenerator. Several process configurations for the conversion of C 3  and C 4  alkanes to their respective alkenes separately or simultaneously by integrating with FCC are provided.

Claim (Index 10):
The process as claimed in  claim 8 , wherein the process comprises:\n a) sending the flue gas from the FCC regenerator to CO 2  recovery unit for CO 2  separation, wherein the remaining flue gas is released to stack, b) mixing the CO 2  gas with ethane from ethylene recovery section and sending to feed mixture to the fluidized bed riser type of reactor; c) mixing the CO 2  gas with the propane from PRU and sending feed mixture to the fluidized bed riser type of reactor; d) mixing the CO 2  gas with C 4  alkanes from C 4 -separation section and sending the feed mixture to the fluidized bed riser type of reactor; e) introducing the feed mixtures from step (b), (c), and (d) separately at different zones of the fluidized bed riser type of reactor to produce ethylene, propylene, and butylene; f) continuous circulation of catalyst from the reactor to catalyst regeneration unit; g) re-circulating the hot catalyst to the reactor; h) re-routing the products from step (e) to the gascon section after separation of water.
