A method/system, which can be modified from the Flexicoking™ process/system, includes introducing a heavy petroleum feed into a fluidized bed in a reactor and converting the feed via a coking operation within the fluidized bed, producing an overhead stream with entrained coke fines from the reactor overhead and solid coke from the base of the reactor. The method includes injecting the solid coke into a fluidized bed in a burner and combusting the solid coke in the burner, producing hot coke particles. The method includes recirculating a portion of the hot coke particles to the fluidized bed in the reactor, discharging the remainder of the hot coke particles from the base of the burner and a flue gas from the burner overhead, and passing the flue gas and a caustic dispersion to a venturi scrubber to obtain a scrubbed flue gas. More petroleum coke can be produced from the method/system.
