Introduction
The Sodium Sulphate manufacturing process is designed to produce a chemically stable, high-purity industrial material used in detergents, textiles, glass, paper, and chemical industries. The process is efficient, scalable, and cost-effective, making Sodium Sulphate one of the most widely produced inorganic chemicals.
Raw Materials Used
Depending on the production route, common raw materials include:
Sodium Chloride (NaCl)
Sulphuric Acid (Hâ‚‚SOâ‚„)
By-product streams from chemical industries
Water
Major Methods of Sodium Sulphate Manufacturing
🔹 1. Mannheim Process (Most Common Industrial Method)
This is the traditional and widely used Sodium Sulphate manufacturing process.
Process Steps:
Sodium Chloride is charged into a Mannheim furnace
Concentrated Sulphuric Acid is added gradually
Controlled heating is applied
Sodium Sulphate is formed as a solid product
