Sodium Chlorate Production ¾ ¾
Production of sodium chlorate is by the electrolysis of sodium chloride (salt) solution The process is electricity intensive and uses around 5,200 kWh per ton produced 1)
Process: 2) ¾ The process is similar to Chlor Alkali production ¾ Technology is similar to a diaphragm cell but without a separator
