Biofuel Filtration


Biodiesel is a biofuel that belongs to the first generation biofuels. The feedstocks of biodiesel are pure vegetable oil, animal oil, animal fats and waste oil. Biodiesel is obtained from the animal and vegetable oil by a conversion process called transesterification. In order to perform an optimized transesterification process and to meet the requirements of the regulations many contaminants have to be removed like plastics, gums and Free fatty acid (FFA). As separation step filtration can be used to remove a lot of these impurities. Filtration can be used in several steps during the biodiesel production process. The use of filtration depends on the used feedstock. The use of filtration during biodiesel production can be divided in two steps the pre-treatment of the crude oil and the purifying of the crude biodiesel.

Filtration can be used in general for:

  • removal of polyethylene and other plastics from the animal oil
  • removal of sterols
  • removal of glucosides
  • pre-treatment to make the oil clean enough for the conversion of oil into biodiesel
  • bleaching of the animal oil
  • removal of sulphur from the animal oil
  • removal of proteins from the animal oil
  • removal of absorbents like silica
  • removal of phosphorus
  • removal of mono-glyceride (In normal cases 0,6-0,4 % is acceptable, when lower is required another purification step should be considered)
  • removal of strains
  • removal of waxes and gums
  • washing, drying and purification of the end products biodiesel and glycerine
  • removal of polycyclic aromatic hydrocarbons (PAHs)
