| titleOfInvention | Method for producing calcium carbonate |
| abstract | A method for producing calcium carbonate. In the method, the calcium oxide material is contacted with carbon dioxide in an aqueous phase in a plurality of carbonation units. In the present invention, the calcium oxide material is carbonated in an aqueous slurry at a pH of more than 11.0 in the first carbonation unit to produce calcium carbonate in the aqueous slurry, and from the first carbonation unit, calcium carbonate and The discharge formed by the aqueous slurry containing calcium hydroxide is taken out, and then the calcium hydroxide in the taken-out discharge is carbonated in the second carbonation unit to produce a calcium carbonate slurry having a pH of less than 6.9. To do. In this method, it is possible to produce both monodisperse particles having a narrow molecular weight distribution and polydisperse particles having a wide molecular weight distribution. |
