Abstract

Методология приготовления бикарбоната натрия и сульфата калия. В одном варианте способа по настоящему изобретению для удаления карбонатов с последующим осаждением сульфата калия сульфат натрия и бикарбонат аммония вступают в реакцию с образованием бикарбоната натрия и раствора или солевого раствора, обрабатываемого серной кислотой. В другом варианте способа по настоящему изобретению для осаждения бикарбоната натрия используется бикарбонат аммония, аммиак или двуокись углерода. В результате использования способа по настоящему изобретению получается высококачественное минеральное удобрение и пищевой бикарбонат натрия.Международная заявка была опубликована вместе с отчетом о международном поиске.Methodology for the preparation of sodium bicarbonate and potassium sulfate. In one embodiment of the process of the present invention, to remove carbonates, followed by precipitation of potassium sulfate, sodium sulfate and ammonium bicarbonate react to form sodium bicarbonate and a solution or saline treated with sulfuric acid. In another embodiment of the process of the present invention, ammonium bicarbonate, ammonia or carbon dioxide is used to precipitate sodium bicarbonate. As a result of using the method according to the present invention, high-quality mineral fertilizer and edible sodium bicarbonate are obtained. The international application was published together with an international search report.
