Calcium Hypochlorite Production via Sodium Method - Cost Analysis - Calcium Hypochlorite E11A

Book excerpt: This report presents a cost analysis of Calcium Hypochlorite production from slaked lime, sodium hydroxide and chlorine. The process examined is a typical sodium process. This process consists mainly in passing chlorine into a slurry of slaked lime and sodium hydroxide, generating Calcium Hypochlorite and sodium chloride. After separation steps, Calcium Hypochlorite (about 70 wt%) and an aqueous solution of sodium chloride are obtained as products.
