Chemical Recovery serves several important functions in a modern pulp mill: it removes water from the weak black liquor in evaporators and concentrators to enable incineration of the black liquor, it selectively removes organic contaminants from the water to allow for reuse in the pulp mill, it incinerates the concentrated black liquor in the recovery boiler, it recovers heat from the incineration process for steam generation, and it dissolves the produced chemicals in water for future processing for pulping liquor generation.
