Abstract: |
|||
| A salting-out process for preparing potassium sulfate from sulfuric acid, potassium chloride and ammonia includes such steps as low-temp reaction of potassium chloride on sulfuric acid to generate potassium hydrogen sulfate, addition of potassium chloride to prepare its aqueous solution, low-temp. neutralization with ammonia to generate potassium sulfate and ammonium chloride and water washing to separate potassium sulfate. Its advantages are high transform rate of K and quality of product, low corrosion to apparatus, and low technological temp., energy consumption and cost. | |||
