| Abstract: | Black liquor, obtained from paper production using agricultural residues, contains additional silica, removal of which or desilication is complex process. Carbonation involves accurate control of pH, as lignin also co-precipitates around the same pH of desilication. Present work used high mass transfer efficient, Bubble Column Reactor (BCR) for desilication. Carbonation in BCR (5 l) at higher temperature was observed more efficient than at room temperature. |
