Sodium hydroxide production process
The modern sodium hydroxide industry mainly adopts the Chlor-Alkali Process, using refined brine as the main raw material. Through electrolysis reactions, sodium hydroxide is produced, and at the same time, chlorine gas and hydrogen are also produced as by-products.
Caustic Soda Production Line 's process flow includes
Raw salt → Salt water preparation → Salt water purification → Secondary purification → Electrolysis → Sodium hydroxide solution → Evaporation and concentration → Finished product storage/packaging
According to product specifications and customer requirements, subsequent processing systems such as liquid sodium hydroxide concentration, sheet sodium hydroxide or solid sodium hydroxide can be further configured.
