Experimental Study of Parameters Influencing the Purity of Potassium Sulfate Fertilizer Produced from Jordanian Raw Materials

The general objective of the present investigation was to make a contribution towards improving the purity of the produced potassium sulfate from (KCl, Arab Potash Company-Dead Sea) and (H₂SO₄, Jordanian Phosphate Company). The process parameters influencing the contamination of the poisoning chlorine within the product were experimentally investigated. The experiments were performed in a small-scale batch reactor equipped with a high temperature control system. The role of temperature was studied. Higher purity of potassium sulfate was achieved at higher temperatures. The effect of the quality of KCl used was investigated. It was found that implementing fine KCl as reagent is a dvantageous over standard KCl. A completely pure potassium sulfate fertilizer was produced after 110 minutes residence time in the case of using fine KCl.
