Sodium sulfate is a common low-value industrial by-product but can be managed using the Glaserite process to convert it into high-value potassium sulfate. The aim of the study is to investigate the potential for implementing this process in an industrial application. Experimental studies were completed to determine the yield and purity of both glaserite and potassium sulfate. Process simulation using SysCAD was utilized to optimize a two-stage glaserite process to produce potassium sulfate. Comparison of experimental and simulated data was made to validate the simulator’s results, finding the AAD in solid and liquid phase for glaserite production to be 6.9% and 5.7%, respectively, and for potassium sulfate to be 5.7% and 2.3%, respectively. For a process treating seven MT/hr of Na₂SO₄, a KCl feed strategy of 3.0 MT/hr to the glaserite reactor and 4.5 MT/hr to the K₂SO₄ reactor was found to maximize yield and minimize water demand. It was also found that ambient temperatures were preferred for the K₂SO₄ reactor and that K₂SO₄ yield suffered significantly under certain conditions when the glaserite reactor operated at 50°C or above.

硫酸钠是一种常见的低价值工业副产品，但可以使用Glaserite工艺进行管理，将其转化为高价值硫酸钾。该研究的目的是调查在工业应用中实施此过程的潜力。已完成实验研究，以确定玻璃矿和硫酸钾的产率和纯度。利用SysCAD进行的过程模拟可优化两阶段玻璃矿的生产过程，以生产硫酸钾。通过对实验数据和模拟数据进行比较，以验证模拟器的结果，发现在固相和液相中对玻璃矿的AAD分别为6.9％和5.7％，对于硫酸钾的AAD分别为5.7％和2.3％。用于处理7 MT / hr的Na ₂ SO _4的过程，发现向玻璃质石反应器中3.0 MT / hr和向K ₂ SO ₄反应器中4.5 MT / hr的KCl进料策略最大程度地提高了产量，并使水需求最小化。还发现对于K ₂ SO ₄反应器优选环境温度，并且当玻璃石反应器在50℃或更高温度下操作时，在某些条件下K ₂ SO _4的产率显着降低。
