Anhydrous Crystallization System. The facility at ayrhan, near Ankara, is designed to produce 120,000 tpa (tons per annum) of refined sodium sulfate. The process begins with solution-mined Glauberite from natural deposits that are converted to Glaubers Salt as the first purification
Sep 13, 2018 A process has now been discovered for obtaining a sodium sulphide of excellent purity by reduction of sodium sulphate with carbon or other reducing agents, which sulphide is in particular free from iron and water. The process is based on the fact that anhydrous sodium sulphide, unlike the hydrate, dissolves readily in alcohols.
Sodium sulfate ( Na2SO4) is the sodium salt of sulfuric acid. Anhydrous sulfate is a white crystalline solid also known as the mineral thenardite, while the decahydrate Na 2 SO 4 .10H 2 O has been known as Glaubers salt or mirabilis. Na 2 SO 4 .7H 2 O is transformed to mirabilite when it is cooled.
