This salt is then separated from its mother liquor、melted、and dehydrated with mechanical vapor recompression evaporators. Processing at Searles Lake、California、is similar to that of Texas brines. Brine is cooled to 16 °C to remove borax crystals then cooled to 4 °C、which precipitates Glauber's salt. This salt is then separated from its mother liquor、melted in multi-effect vacuum crystallizers to form anhydrous sodium sulfate、and dried. Both processes produce crystals that are 99.3-99.7% pure.、The Mannheim process produces sodium sulfate by reaction of sodium chloride and sulfuric acid. This reaction takes place in a fluidized-bed reactor or a specially made furnace called a Mannheim furnace. This method was last used in the United States in the 1980s. In another process、SO2、O2、and H2O react with NaCl. This is called the Hargreaves process. Only a minor amount of sodium sulfate is made in the United States using the Hargreaves process、but both the Hargreaves and the Mannheim processes are used widely in the rest of the world.、It is prepared by the neutralization of sulfuric acid with sodium hydroxide.、(1) Purification of natural sodium sulfate from deposits and brines、(2) by-product of hydrochloric acid manufacture from salt and sulfuric acid ...
