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 5):
The process as claimed in  claim 1 , wherein the process comprises:\n a) feeding cracked hydrocarbon products from FCC riser-reactor to a main fractionator column to obtain a product stream comprising of dry gas, LPG, and light naphtha, b) separating the product stream in a gascon section, into LPG comprising of C 3  and C 4  hydrocarbons, and dry gas comprising hydrogen, methane, ethane, ethylene, and other non-condensable gases, c) routing the LPG stream to propylene recovery unit (PRU) to separate and obtain C 4  hydrocarbon stream from debutanizer section, d) routing the C 4  hydrocarbon stream to the C 4 -separation section to separate and obtain C 4  alkanes comprising iso-butane and n-butane, wherein the iso-butane or n-butane or their mixture is used as feed stream for the ODH process, e) subjecting the flue gas from FCC regenerator to carbon dioxide (CO 2 ) separation to recover CO 2 , wherein the remaining flue gas is released to stack, f) premixing the C 4  feed stream obtained from step (d) and the recovered CO 2  from step (e) and utilizing the mixture as feed mixture for ODH process to obtain butylenes, unreacted butane(s), C 2 , C 3 , and other hydrocarbons, g) re-routing the products from step (f) to the gascon section after separation of water.
