It ‘a biofuel produced through a transesterification reaction, a process in which a vegetable oil is reacted in excess of methyl alcohol, in the presence of an alkaline catalyst. The final product is a mixture of some methylesters that does not contain sulfur and aromatic compounds but oxygen in high amounts and can be used as fuel for transport and heating.

The plant includes a unit of physical deacidification of oils and fats which is separated by distillation in a current of fatty acids.
The product obtained, consisting of high-concentration acid is used in the chemical industry or the animal feed.

Glycerin is a byproduct of the transesterification reaction in the biodiesel production.
Crude glycerine obtained is processed in the system of the DP Lubricants that includes all stages of the treatment that is: desolventizing; Purification; Concentration; Distillation and refining.

In the plant of purification of glycerol is separated, as by-product, a vegetable olein current that are used in the chemical industry.

The distillation of Foreign produces a residue composed of raw material unconverted used as fuel in the boiler.
