Tablet salt for the chemical industry - applications and requirements
In the chemical industry, tablet salt is used as a raw material for the production of chlorine, caustic soda and as a process medium. What requirements must it meet?
Salt as a raw material for chlorine-alkali electrolysis
Electrolytic decomposition of NaCl brine (chloralkali electrolysis) is one of the most important processes in the chemical industry. The products arechlorine (Cl₂), sodium hydroxide (NaOH) and hydrogen (H₂). The process requires very pure salt (NaCl ≥99.9%).
Quality requirements for the chemical industry
- NaCl: ≥99.5–99.9%
- Sulphates (SO₄²⁻): ≤200 mg/kg
- Calcium and magnesium: ≤10 mg/kg total
- Heavy metals: below industry standard limits
Process water treatment
In chemical plants, tablet salt is used primarily to regenerate water softeners feeding steam boilers and cooling towers. Requirements for the food industry: PN-EN 973.
