Abstract
A pyrolysis process for converting a hydrocarbon mixture to produce olefins including preheating a hydrocarbon feed, mixing the pre-heated hydrocarbon stream with a steam feed, feeding the mixed hydrocarbon steam stream to a second preheat zone, heating air, combusting the combustion air feed, cracking hydrocarbons, recovering a cracked hydrocarbon product, and quenching the cracked hydrocarbon product. A pyrolysis system for converting a hydrocarbon mixture to produce olefins including a pyrolysis heater, a first and a second preheat zone of a convection heating zone, an electric heater, a heat transfer fluid heating coil, an air feed electric heater, a radiant heating zone, and a feed line. Also disclosed is a process for retrofitting an existing pyrolysis system including removing a secondary transfer line exchanger, adding an electric heater, adding a flow line, replacing or repurposing one or more coils, and adding an air feed electric heater.
