The Garmsar Sodium Sulfate Factory

With an annual nominal capacity of 30,000 tons, this factory was constructed on 30 hectares of land 35 kilometers on the Garmsar-Semnan road. Project construction began in October 1991 and was inaugurated and launched on August 1994 by the late Former President Akbar Hashemi Rafsanjani.
The unit's required water is supplied from a deep well 17 kilometers away, and the total foundation area of the factory's buildings is 7500 m².
Ebner GmbH designed and produced most of the equipment for this factory from high-chrome special alloys.
After the Garmsar Factory was launched, Iran, formerly an importer of Sodium Sulfate, could now export the product overseas. Shortly after launch, the price of imported sodium sulphate, which was suffering from a shortage, fell from $250 to less than $120 per ton.
The removal of production obstacles, optimizing equipment, and decreasing stalls continuously increased output, and the unit’s current annual capacity of approximately 59,000 tons is nearly twice its nominal capacity.

In recent years, a glauberite stone sodium sulphate mine (double sulfate of sodium and calcium) was discovered 30 kilometers in northeast Semnan County, which is unique in Iran. Presently, this mine (Garmab) supplies some of the Garmsar factory's mineral needs, and the exploration for discovering the main mine in underway.
This factory produces industrial sodium sulphate with a minimum purity of 99.5% for use in detergent and glass industries.
The powder required by glass producers is produced and offered with special considerations for minimum fine particles (sub-50 micron particles) and lower than 2 ppm iron.
The glass production powder's chemical specification and grading table is presented in the annex.
