Salt and Marine Chemicals
Application Uses
For production of salt to be used as raw material in chlor alkali industries
Salient Technical Features
The process is an improvement over the existing process of producing salt of high purity from alum-treated brine. More particularly, the invention rectifies the ratio of Ca2+ to Mg2+ from a value <1 to a value in the range of 2-3 desired by chlor-alkali and soda ash industries.
TRL
Business scope & opportunity
The technology is ready for technology transfer and can be implemented on commercial scale. The product has high demand in chlor-alkali industrial sector.
