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.
