Abstract

A new continuous process for producing sodium carbonate and ammonium sulphate from naturally occurring sodium sulphate is disclosed. The process comprises reacting sodium sulphate in aqueous solution with ammonia and carbon dioxide to precipitate sodium bicarbonate which is separated by filtration and converted by calcining to sodium carbonate. The mother liquor from the precipitation of sodium bicarbonate is concentrated by evaporation to precipitate unreacted sodium sulphate, cooled to precipitated ammonium sulphate and further cooled to precipitate a double salt of sodium and ammonium sulphate. The double salt is added to the mother liquor from the precipitation of sodium bicarbonate, prior to the evaporation, whereas the mother liquor from the precipitation of the double salt is concentrated by evaporation and added to the mother liquor from the separation of sodium sulphate. The process, in addition to producing sodium carbonate, also produces ammonium sulphate in a purity such that it can be immediately used as a fertilizer. The process does not produce any unwanted byproducts and avoids the use of complicated equipment, such as absorption towers.
