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

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
