Pyrolysis

Pall helps solve some of the most complex filtration and separation challenges faced by pyrolysis oil producers, licensors and end users.

Pyrolysis involves the thermal decomposition of waste plastic under an inert atmosphere. A reactor breaks down the plastics at temperatures of 400°C-600°C into smaller hydrocarbon molecules. The resulting gas is cooled and treated to get Pyrolysis Oil - an oily mixture of liquid hydrocarbons which can replace virgin fossil fuel sources as a feedstock for the production of liquid fuels and petrochemicals.

Why is filtration important?

 

Pyrolysis oil contains contamination with complex characteristics, featuring:

 

  • Fine solids (less than 50 µm) 
  • Sticky semi-solids or gums
  • Water-based contamination or solvents from upstream processes

 

The nature and concentration of contamination are often highly variable due to differences in the type of plastic waste feed and the pyrolysis process employed. The contamination also evolves with time due to further degradation.
