Abstract: |
|||
| The process for producing fertilizer of potassium ammonium sulfate with potassium chloride and sulfuric acid includes putting potassium bisulfate and ammonia or ammonium bicarbonate or ammonium carbonate into ammoniation tank containing saturated mother liquid of potassium ammonium sulfate for ammoniation, and centrifugal separation to obtain binary mixed fertilizer. The recovery of potassium in raw material reaches 100%. It may be mixed with P and N fertilizers to obtain ternary mixed fertilizer. | |||
