LPS [Lignin Precipitation System] A process for removing lignin from the black liquor produced by the
soda pulping process, fed by annual plant crops. Developed by Granit SA, Switzerland, and rst operated at
Papeteries du Léman, Thonon, France, in 2000. The liquor is ltered, acidied, aged, and ltered again to
separate the lignin. This produces a liquor, which can be processed in municipal sewage treatment plants, and
a saleable lignin product.
