The basic raw material for the membrane Chlor-Alkali process is purified Sodium Chloride. The quality of salt plays an important role in the proper trouble-free production of Chlorine and Caustic Soda (Sodium Hydroxide). The introduction of membrane technology into the Chlor-Alkali Electrolysis has increased the demand for quality salt. The quality of the salt used as raw material determines the life of the membrane cells. On the other hand, the consumption of electricity is dependent on the level of impurities in the salt.
Hub-Pak specializes in the production of chemically pure salt for this application and offers a little better than what is needed to save cost in running, as well as in capital by the Chlor-Alkali industries. There are four different grades being offered to this sector. A special grade amongst these is absolutely trace-free from Ca, Mg, S04-2Sr, Ba, Al, Fe and TOC.
