Black Liquor Evaporation

Weak black liquor is collected as filtrate from brownstock washers at a dry solids content between 14 wt% and 18 wt%. In order for an evaporation plant to remove water from black liquor to be fired in a recovery boiler, the black liquor must be concentrated to between 65 wt% and 85 wt% dry solids content.
