Abstract
The conventional black liquor regeneration process is not always suita ble for pulping plants of nonwood fibers due to the unfavorable ratio of organic to Inorganic solids. This paper presents an alternative tre atment based on an electrolysis process of the soda black liquor from straw pulping. This alternative method minimizes the environmental imp act by recovering the caustic at the same time that the liquor is acid ified, which favors the later separation of the lignin.
