| Abstract: | Some technical conditions of producing potassium sulfate with phosphogypsum and potassium chloride by adding proper solvent are studied. Some technical conditions for the reaction system with ammonium solution are researched,and in view of the questions of the low reaction temperature and the high concentration of ammonium, some organic solvents are studied and one of them is selected as the proper solvent to improve the technical conditions. The results of the experiment with the proper solvent show that the technical conditions of reaction and the transform rate of reaction are improved further, and the quality of the obtained potassium sulfate reach related standards. The process of reaction is short, the operational condition is mild, and the solvent can be recycled and reused. |
