Sodium sulfate production
Sodium sulfate is a popular raw material for the production of synthetic detergents, as well as in glass, cellulose, textile, leather and other industries.
Due to the fact that the industrial method of obtaining sodium sulfate by the direct reaction of sodium chloride and sulfuric acid is currently practically not used, and the number of natural sources of this raw material on the territory of Russia is very limited, recently methods of obtaining this salt have become more relevant. from sulfate-containing effluents, which are waste products of hydrometallurgy and various inorganic substances.
Since saline streams potentially suitable for the production of sodium sulfate usually have a rather complex component composition, the extraction of the target substance from them is a task that requires not only specific knowledge in the field of production of sulfate salts, but also preliminary research and technical and economic calculations in order to determining the feasibility and payback of such production in each specific case.

We are ready to offer you an integrated approach to the implementation of sodium sulfate production processes - from the analysis of feed streams and audit of existing lines, to the development and implementation of an effective technology based on the processes of evaporation, fractional crystallization and obtaining a dry pure product, using methods of reducing carbonate load, extracting associated waste salts and environmental issues if necessary.
