MOTT FILTERS FOR FCC/RFCC SLURRY Mott Corporation HyPulse® LSI filters excel at removing alumina-silica catalyst and other solid contaminants from FCC/RFCC main column bottom slurry feeds. With online clean-inplace backwashing and automated process control, Mott slurry oil filters achieve less than 100 ppm total suspended solids filtrate quality, ensuring the filtered oil can be used for blending or sold as valuable product into other applications. Backwashed slurry can be recycled back to the riser, decanted and concentrated, or sent directly to disposal or reprocessing, depending on the individual refiner’s needs. Mott’s installation list includes 20+ filters on five continents in both FCC and RFCC applications. References are available upon request. MOTT PROJECT INSTALLATION SPECIFICATIONS Filter Diameter Solid Weight % Operating Temperature Particulate Size 3 REASONS TO USE A MOTT FILTER FOR FCC/RFCC SLURRY 1. UPGRADE SLURRY OIL FOR USE AS A MARINE (OR OTHER) FUEL Mott porous metal filters can achieve higher quality filtrate (< 50 ppm in most cases) than settling tanks or other technologies while occupying only a fraction of the footprint. 2. UPGRADE SLURRY OIL TO NEEDLE COKE (HIGH-GRADE PETROLEUM COKE) The quality of the filtered slurry oil easily meets the feedstock requirements for the production of needle coke used to manufacture graphite electrodes. 3. ELIMINATE LARGE STORAGE ISSUES AND SLOP TANK CLEANING With the ability to recycle slurry back to the riser, or concentrate and dispose, the Mott HyPulse LSI eliminates the need to clean out slop tanks, thereby saving money and reducing environme
