A method for processing a hydrocarbon feed to produce olefins may comprise introducing the hydrocarbon feed to a first fluid catalytic cracking system, which may cause at least a portion of the hydrocarbon feed to undergo catalytic cracking and produce a spent first cracking catalyst and a first cracked effluent comprising one or more olefins. The method may further comprise passing the first cracked effluent to a separation system downstream of the first fluid catalytic cracking system, which may separate the first cracked effluent to produce at least a naphtha effluent comprising one or more olefins. Additionally, the method may comprise passing the naphtha effluent to a second fluid catalytic cracking system downstream of the separation system, which may cause at least a portion of the naphtha effluent to undergo catalytic cracking and produce a spent cracking catalyst mixture and a second cracked effluent comprising one or more olefins.
