BUSINESS SCOPE
The sodium sulfate finds wide usage in the chemical industry.
The main consumers are those in glass. fiber, paper and detergent industries
The ways to produce sodium sulfate are either from natural resource or by chemical reaction.
Sodium sulfate is existed in sea or lake brine water, sodium sulfate/sodium carbonate salt water, and salt mines that contain Glauber salt, white sodium magnesium alumina, anhydrous Glauber salt and other mineral deposits where magnesium sulfate that are contained in water are found. They are further divided into beach-field method and mineral rocks method. The sea brine or lake brine are used in beach-field method, while the mineral method is using salt rocks found in lower rock layer of deep mine shaft.
Another way is by chemical reaction between sodium chloride and sulfuric acid, where Mannheim furnace is used, inside which agitating devices are installed. This process yields not only sodium sulfate but also hydrochloric acid as by-product.
