Calcium Hypochlorite Production Process. Production of calcium hypochlorite from slaked lime, sodium hydroxide and chlorine, is a typical so-called "sodium method calcium hypochlorite production process". Typical Calcium Hypochlorite Plant Design.
1. 100kg of calcium hypochlorite 65% into 1 MT of water. The solution will be bleaching liquid at a density of 6.5% effective chlorine. 2.1% disinfection liquid can be formulated by adding 1.7 g of calcium hypo 65% into 1 MT of water. Advantages: 1) High effective chlorine content; 2) Good stability.
Today, an improved version of this method, known as the Hooker process (named after Hooker Chemicals, acquired by Occidental Petroleum), is the only large-scale industrial method of sodium hypochlorite production. In the process, sodium hypochlorite (NaClO) and sodium chloride (NaCl) are formed when chlorine is passed into cold dilute sodium ...

The chemical manufacturing processes for calcium hypochlorite, 151 sodium hypochlorite, and chlorine dioxide are described below. 152 153 Calcium Hypochlorite6 154 155 Calcium hypochlorite is produced by passing chlorine gas over slaked lime.7 It is then separated from the
PDF | This work is focus on the production of calcium hypochlorite, this was achieved by running chlorine gas into four sample bottles containing prepared solution of Ca(oH) at the same flow rate ...
These chloralkali plants, which use salt and electricity to make chlorine, caustic soda, and hydrogen on-site, can be used primarily for the production of sodium hypochlorite, ferric chloride, calcium hypochlorite, hydrochloric acid, and other chlorine derivatives. It can also be used to produce feed stocks for a variety of other chemicals.
This report presents an up-to-date, detailed 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.

Sanitation. Calcium hypochlorite is commonly used to sanitize public swimming pools and disinfect drinking water.Generally the commercial substances are sold with a purity of 65% to 73% with other chemicals present, such as calcium chloride and calcium carbonate, resulting from the manufacturing process.
Calcium hypochlorite is more stable than sodium hypochlorite, and contains a higher chlorine concentration (30-75%). Like sodium hypochlorite, calcium hypochlorite also increases water pH, so it is advised to acidify the water during the disinfection process. All forms of calcium hypochlorite contain insoluble residues that form sediments in ...
