For more than 20 years, Quimetal has been supplying the main pulp and paper manufacturers in our country, such as the Arauco and CMPC groups, among others. In this place, chemical reagents essential for its production process are produced, such as sulfur dioxide (SO2), sodium bisulfite, aluminum sulfate and magnesium sulfate.
Sulfur Dioxide (SO2)
In the cellulose and paper industry this inorganic reagent is used to reduce chlorine residues in the cellulose production process.
The main application of this compound occurs in the treatment of water that is released from the production process in cellulose plants, as flocculant in the treatment of sanitary water and as a sticker in the paper industry.
