Filtration of Fines from (Hot) Process Gas
Introduction to Slurry Oil Filtration I
Targets of FCC Slurry Oil Filtration
Convert low grade product in valuable commodity
Expand market for FCC bottom product Reduction of wear in downstream equipment
Reduction of tank cleaning costs
Reduction of sludge disposal costs
Introduction to Slurry Oil Filtration II
Profitibility of Slurry Oil FiltrationPotential usage for filtered slurry oil
Carbon black feedstock 50-500 ppm No. 6 or Bunker C. fuel oil 50-150 ppm Coker feedstock 50-150 ppm Anodic/ needle grade coke/ pitch feedstock 25-100 ppm Boiler or Furnace oil 50-150 ppm Industrial and electric utility fuel 50-100 ppm Carbon fiber production 5-10 ppm Residue hydrocracker feedstock/ diluent 10-50 ppm
Introduction to Slurry Oil Filtration III
Introduction to Slurry Oil Filtration IV
Steel structure with:

Control– Local control panel– DCS or PLC
Slurry Oil Filtration Equipment II
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)
Filter Design Principles
Minimize penetration of contaminants in filter medium
Not depth filtration …Filtration Cycle Cleaning Cycle
A very fine particle
penetrates in the media
The particle gets stuck
in the media
But surface filtration!Filtration Cycle Cleaning Cycle
Minimize penetration of contaminants in filter medium
ROYAL DAHLMAN SINTERED METAL ELEMENTS
Surface filtration Shape stability Suitable for high differential pressure
therefore easily cleanable Wide variety of sizes and materials High permeability with low pressure drop Chemical and heat stability
Proven technology for FCC slurry oil filtration
Filter media
Multi layer laminate with support structures upstream and downstream
Supported by core with 1/8” perforations
