Cat Fines Separation

Systems from GEA Westfalia Separator for cat fines removal from residual oils in refineries

Cat fines removal plant in special design

Improve Oil QualityRefining cat fines

During modern refining processes the resi-

dual oils from atmospheric and vacuum

distillation are sent to a cracking tower.

Here the long hydrocarbons are cracked

with the help of pulverised catalysts such

as aluminium silicates which are mixed

with the oil. This cracking process takes

place at a temperature of approx. 500 °C

(930 °F). A lot of these cat fines remain

in the residues of the cracking tower and

the distillates coming from the cracking

process.

These cat fines can be separated from the

oils to recover them and / or to improve

the oil quality.

Typical refinery process

• Disk stack centrifuges for cat fines

removal (operated as clarifier)

• Due to high product temperature

oil instead of water as operating

liquid recommended

• Downstream cat fines concentration

with decanters possible

Separation results Customer benefits

These top results can be achieved only with oil and water treat-ment systems from GEA Westfalia Separator Group.

Reduction of disposal costs

These cat fines can be reinjected into catalyst tower and re-used
