Step 1: Separation. The first step in the LignoBoost process is to separate the lignin from the mill's black liquor. Black liquor is taken from the evaporation, and the pH is lowered with CO 2 and gas from the second step of the LignoBoost process. When the pH drops, lignin precipitates and is separated from the liquor with a press filter.
