A chlor-alkali plant is a specialized type of chemical plant operations. Using DC power, electrochemical cells split an ultrapure sodium chloride brine into its constituent components, chlorine, hydrogen and sodium hydroxide.
The plant can be separated into the following units:
Cell and Renewal
The critical factor for any chlor-alkali plant is the purity of the brine fed to the cells. The ability to remove low level constituents from the brine is the key to any chlor alkali operation.
