14. FCC Slurry Oil Filtration Technology:
 Minimize penetration of contaminants in filter medium
- > Surface filtration
 Optimal use of filter area at high slurry oil solids content
- > Filtration from inside-to-outside
 Element cleaning needs to be powerful and effective
- > Gas-assisted backwash (steam, nitrogen or (sweet) fuel gas)
 When backwash liquid directed back to riser, continuous flow, with restricted
solids concentration to be realized
- > Sludge removal gas-driven or by recirculation pump(s)
