Crude black liquor, immediately after it has been removed from the fibers in the brown-stock washers, typically has a solids content of about 15% (Tikka 2008; Kousini et al. 2016). According to Bajpai (2017), organic compounds typically comprise about 2/3 of the dissolved solids content of black liquor, and the other 1/3 are inorganic compounds.
