Abstract

The High-severity fluid catalytic cracking (HS-FCC) project is a partnership in technology innovation from conception to full scale commercialization with Saudi Aramco, King Fahd University of Petroleum & Minerals, Nippon Oil Corp, and Japan Cooperation Center, Petroleum. This technology combines mechanical modifications with conventional FCC, including changes in operating conditions and catalyst formulations. The HS-FCC process was successfully demonstrated in a 30 bpd plant at Saudi Aramco's Ras Tanura refinery and in a 500 bpd cold-flow model at Nippon Oil's Yokohama refinery. Experimental runs were conducted using various catalysts, additives, and feed oils. The advantage of the downer in suppressing back mixing was demonstrated, thus increasing the yield of light olefins and reducing dry gas and coke formation. Using paraffinic crude base VGO, a propylene yield of 25 wt % was obtained under HS-FCC reaction conditions. To continue demonstrating for further advancing this technology innovation development towards full scale commercialization, a 3000 bpd HS-FCC plant is well under design and will be under construction in 2009 at Nippon Oil's Mizushima refinery in Japan. The process will help many refiners worldwide to meet the expected challenges for producing increased valuable yields of propylene, butylenes, and other light olefins.
