Soda Ash Production Process

FIELD: inorganic compounds technologies. SUBSTANCE: ammonia process for producing soda ash comprises preparation (in absorption stage) of ammonia-saturated purified brine, preliminary carbonization of ammoniated brine, carbonization of pre-carbonized liquid, separation of resulting hydrocarbonate on filters, washing with water at 30-40 C to remove chloride ions, calcinations of

    About 30% of world soda ash production (90% of this is in U.S. alone) is from natural deposits and the rest 70% from synthetic process. Soda ash is a white, finely crystalline, hygroscopic powder. When freshly packed, contains at least 98.5% Na2CO3. It absorbs moisture and carbon dioxide from the atmosphere during storage and transit
