how to mill lignite

Lignin extraction process - Valmet

The Stora Enso Sunila mill is designed to produce 50,000 metric tonnes of lignin per year, or 22 percent of the lignin. Lignin lean black liquor and wash water can be evaporated like a normal black liquor, and if the production of pulp is increased and the mill's energy consumption is reduced, up to 70 percent of the lignin can be removed .
