FCC RISER DISCHARGE SEPARATION AND QUENCH (D#79,433-F) ABSTRACT OF THE DISCLOSURE In a fluid catalytic cracking (FCC) process riser reactor effluent is rapidly separated into spent catalyst and hydrocarbon product. The separated hydrocarbon product is immediately quenched to an unreactive temperature in the absence of quenching spent catalyst. An increase in debutanized naphtha yield is achieved. By avoiding catalyst quenching, heat duty is saved in the catalyst regenerator.
