| Technology Brief |
The production of biomethanol begins with the sulphate pulp process at our mill. Wood chips are cooked with chemicals to separate the wood into its constituents, i.e. cellulose and hemicellulose (pulp) and lignin. Methanol is created when the wood and chemicals react.
After cooking, the chemicals, lignin and other residues are washed out of the pulp. They form black liquor, whose water content is then reduced by evaporation. What remains is a condensate of methanol, turpentine and sulfur compounds.
The condensate is cleaned to be reused in the mill and then raw methanol is created, which is a mixture of combustible residues. In normal cases, raw methanol is burned to produce heat and energy. But thanks to a patented extraction process, we can now produce a commercial grade methanol product instead. For every ton of pulp that leaves our mill, we can produce about 10 kg of biomethanol.
