Tall oil

From tall oil to perfume

SunPines delivers innovative and sustainable products based on tall oil, a sustainable residual product from pulp mills. From the forest biomass we make pine diesel, bio-oil, resin, turpentine and district heating.

Our products reach the world market in everything from Preems Evolution’s diesel to fragrant perfume.

Tall oil is perhaps the most versatile of all forest products. It is used e.g. in the production of biofuels and it can be fractionated into quantities of substances with different properties. In the production of biofuels, tall oil helps to reduce carbon dioxide emissions significantly.

Tall oil often replaces fossil-based substances. Everywhere in our everyday life is pine oil – in soap, glue, tape, facade and wall paints and countless other products. Together with our owners and customers, we find more areas of use all the time.

Manufacturing

Crude pine oil is produced from crude pine soap, which is extracted from black liquor from the sulphate pulp industry. Crude pine oil comes from the so-called extractives in the wood raw material and is called crude tall oil regardless of which type of wood the raw material consists of.
Crude pine oil is extracted by separating the crude pine soap from the black liquor in special liquor tanks. The raw pine soap is then treated with sulfuric acid to regenerate the various organic acids. The conversion from soap to tall oil is generally carried out at the sulphate pulp mills, while further processing is carried out at units other than the mills.
Crude tall oil contains valuable chemical substances, which can be further processed by distillation into various components such as fuel or “green” chemicals.
