Abstract: The chemical pulping of agricultural residues poses no problem however major difficulty arises in recovery of heat and chemicals from cooking chemical (black liquor) due to presence of silica in it, at every stage of chemical recovery. Desilication of black liquor is achieved by carbonation effecting delignification. Filtration is a key unit operation in successful desilication technology. Low temperature and low flocculent dose is found to favor sedimentation rate. Filtration of carbonated black liquor using leaf filter shows that temperature favors rate of filtration. Co-precipitation of lignin makes filtration difficult.
