Removal of silica from spent liquors of alkaline non-wood plant fiber pulping. When using non-wood annual plant as raw material for pulping a considerable amount of silica (SiO2) is carried into the process, which prohibits recycling of the quick lime to the causticizing process. The desilication of the black liquor requires steam boiler flue gas as the only reagent. Precipitated matter is separated from the liquor by means of conventional mechanical systems.
