Thermal Energy Recovery Devices For Electrically Heated Cracking Processes

Abstract: A method to produce olefins may include at least one cooling step in a thermal energy recovery by supplying a hydrocarbon feed to an outer tube of the thermal energy recovery assembly; heating the hydrocarbon feed in the outer tube of the thermal energy recovery assembly to output a preheated hydrocarbon feed; supplying the preheated hydrocarbon feed to an electrically powered cracking furnace comprising a reaction zone to heat the preheated hydrocarbon feed; cracking the preheated hydrocarbon feed in the reaction zone of the electrically heated cracking furnace using heat generated by electricity to output hot reactor effluent comprising cracked hydrocarbons and olefins; supplying the hot reactor effluent to an inner tube of the thermal energy recovery assembly; cooling the hot reactor effluent in the inner tube of the thermal energy recovery assembly by transferring heat to the hydrocarbon feed; and where the inner tube outside temperature in the thermal energy recovery assembly stays below 720°C and the inner tube inside temperature in the thermal energy recovery assembly remains above 180°C.
