Title: Production of aqueous solution of calcium chloride
Inventor: KAWAMURA YOSHITO
IPC: C01F11/24
Filed: 1983-06-22
Abstract: PURPOSE:To produce an aqueous solution of CaCl2 having high concentration, by adding quicklime to an aqueous solution containing NH4Cl, and reacting the components with each other while pulverizing the quicklime. CONSTITUTION:Quicklime is added to an aqueous solution containing NH4Cl, and the components are made to react with each other while pulverizing the quicklime. The surface of the quicklime granule reacted with NH4Cl is covered with a double salt such as CaCl2. Ca(OH)2.nH2O (in the case of using a mother liquid after the separation of sodium bicarbonate, further CaCO3.CaSO4) to inhibit the reaction with NH4Cl, however, the product at the surface of the granule can be removed by the puverization of quicklime, and the reaction with NH4Cl is promoted. When e.g. the mother liquid left after the separation of sodium bicarbonate in the ammonia-soda process is used as the NH4Cl-containing aqueous solution, an aqueous solution of CaCl2 of about 19wt% concentration can be obtained without using concentration process.
