Detail Cantuman

PCC is using in many industrial activities, some of them are paper manufacture, plastic, rubber, cosmetics, food, and other industries. PCC is made from processing limestone which can be made by some methods, like solvay, caustic soda, recarbonizing. The method using in this experiment is recarbonizing method. PCC by this method is made through hydratation, which CaO is dissolved by water to produce slurry. Then this slurry is contacting with C02 gas until it form PCC. To obtain crystal grains, PCC should be filterred and dried up. In this experiment, we can see the influence of sparger internal variation dipping in carbonate tank (H) and sparger diametre (D) against the efficiency of using C02. The efficiency C02 which we have is between 2,35%-4,27%.
