Abstract: Steam cracking of naphtha is one of the major unit processes used in refineries for producing light olefins such as ethylene, propylene which is essentially a thermal cracking process wherein heat energy is supplied to crack the feed molecules. In recent times, the process has gained more importance due to emergence of requirement of increasing petrochemical production from crude oils. The furnace is the heart of the thermal cracking processes in which convection and radiation zone plays a role in providing heat required to crack the naphtha molecules. The conventional preheating of naphtha is done along with steam using heat load of the furnace which consumes huge amount of energy and in turn is expensive as well as results in significant CO2 emissions due to fuel burning. On the other hand, several refiners are exploring ways and means to find greener use of low value Fuel grade Petroleum coke, minimizing the carbon footprint. The present invention discloses a preheating process module integrated with coke handling system in which the overall CO2 emissions of Thermal steam cracking furnace can be reduced substantially by utilizing convection zone energy while making use of energy generation from petcoke coupled with carbon capture.
