Obtaining potassium sulphate by conversion of potassium chloride with ammonium sulfate

Year: 2025

Type: article

Abstract: The process of obtaining potassium sulfate with a basic substance content of at least 95 % is realized under normal conditions. In order to achieve a high content of potassium sulfate in the product, an excess of potassium chloride relative to ammonium sulfate at a weight ratio of at least 1.6 is required. During the dissolution of potassium chloride in a solution of ammonium sulfate, the main factor of obtaining concentrated potassium sulphate is to get the purest possible nuclei of potassium sulfate crystals. The excess of potassium chloride resulting from the synthesis process is utilized by the production of NPKS-fertilizers in liquid and granulated forms.
