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 12):
The process as claimed in  claim 10 , 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 the C 3  hydrocarbon product from PRU and sending the resultant feed mixture to a propane dehydrogenation (PDH) reactor to produce propylene, wherein the feed mixture is pre-heated by PDH reactor effluent stream, and c) mixing the CO 2  gas with C 4  alkanes from C 4 -separation section and sending the resultant feed mixture to a butane dehydrogenation (BDH) reactor to produce butylenes, wherein the feed mixture is pre-heated by BDH reactor effluent stream. d) continuous circulation of catalyst from PDH reactor to BDH reactor and then to catalyst regeneration unit; e) re-circulating the hot catalyst to PDH reactor; f) re-routing the products from step (b) and step (c) to the gascon section after separation of water.
