Some refiners operating an (R)FCC sell their residue from the Fluid Catalytic Cracking Unit as bunker fuel blended into a fuel pool. This is especially attractive when used for blending down Sulphur content of bunker fuels. Problem however is that cat fines concentration in the FCC Slurry Oil stream may be as high as 1000- up to 8000 (ppmwt or mg/kg). Being aware of the limitations of the majority of the onboard fuel treatment systems, most ship engine manufacturers specify a maximum concentration of 15 (ppmwt or mg/kg) at the main engine inlet. Royal Dahlman has developed and proven the filter technology for filtering the FCC Bottoms down to or less than the required cat fines levels.
