Abstract
A process for decoking a convection section of a furnace for cracking a hydrocarbon feed, the furnace comprising a radiant section having burners that generate radiant heat and hot flue gas, and the convection section having at least one heat exchange tube for conveying the hydrocarbon feed. The process includes the step of establishing a flue gas temperature within the convection section of the furnace immediately adjacent the at least one convection section heat exchange tube so as to effect a film surface temperature of less than about 540° C. (about 1000° F.) within at least one convection section heat exchange tube, wherein said flue gas temperature establishing step is effective to decoke the at least one convection section heat exchange tube. A process for cracking hydrocarbon feed in a furnace is also provided.
