K-COTTM TECHNOLOGY

KBR Catalytic Olefins Technology


Introduction to K-COT™

s K-COT™ is KBR’s Catalytic Olefins Cracking Technology(FCC) that processes light Olefinic, Paraffinic or mixedfeeds, resulting in high propylene yields with ethylene andaromatic-rich gasoline by-products.

K-COT Can Simplify Refiners’Growth to Petrochemicals

s Use of K-COT minimizes investment in downstream units– Only ethylene and propylene derivatives together with either

aromatics or high-octane gasoline– All C4’s and light C5/C6NA gasoline can be recycled without

hydrogenation to minimize by-products and enhance light olefinsyields

s Stand-alone K-COT can be economic even for smallnaphtha feed quantities or ethylene production ratess KBR is already working on such projects in China

Summary - KBR Olefins Technology

Suite of technologies are applicable across a wide range of scenarios:,including steam cracking, refinery upgrade, MTO/MTP/CTL upgrade,refinery and petrochemical integration

KBR has much experience in both FCC design and Olefins plantdesign

SCORE is a versatile high yield and low CAPEX steam crackingtechnology

K-COT is extremely flexible in terms of feed and products, and itsversatility can enhance economic performance of steam crackers and /or refiners in a number of ways

KBR’s technologies are ideal to enhance margins in integrated refinery/ petrochemical plants
