【Abstract】 Unit of test with enlarged scale, process flow and raw material specification were introduced for making potassium sulfate by solvent method, through the analysis of reaction process, optimal process condition was determined, material, energy consume and gain were evaluated for the experimental data. Result indicates that under the condition of operating temperature lower than 150 ℃ , qualified potassium sulfate can be produced using the ordinal chemical equipment and byproduct of industrial chlorhydric acid can be made.更多还原
