Naphtha Steam Cracking as Propylene Process

Steam cracking is one of the main processes for producing olefins at present.

The naphtha undergoes molecular chain scission and dehydrogenation reaction at high temperature above 750°C in a water vapor environment through a tubular heating furnace, thereby producing light hydrocarbons such as ethylene and propylene.

The steam cracking technology has a high ethylene yield, but with the increase in the molecular weight of naphtha, the propylene yield will increase positively.
