A method and apparatus for recovering chemicals from an alkaline lignin material |
| abstract |
In a method and apparatus for recovering chemicals from an alkaline lignin material, an alkaline lignin material (3) comprising NaOH or KOH is precipitated in the presence of an acid to form the precipitated lignin (7), the precipitated lignin (7) is ) and recovering at least one fraction (10) comprising Na or K to the crystallization step (11) and treating the fraction (10) comprising Na or K by crystallization to form the crystallized compound (12) in the crystallization step (11). The invention further relates to the use of purified lignin, and lignin and chemical products. |
