Sulfate/Bisulfate Preparation TRIZ Cases
- Electric Sulfate Salt Furnace for Precise Heat Zone Control
Electrical resistors heat furnace walls radiatively to improve sulfate salt production, cut fossil fuel use, and control temperature zones.
- Potassium Sulfate Metathesis Process for Low-Chloride High-K2O Product
A three-stage metathesis route raises K2O content while cutting chloride and water use in potassium sulfate production.
- Potassium Sulfate Crystallization via One-Stage Evaporative Processing
One-stage evaporative crystallization converts KCl and sulfuric acid into purer potassium sulfate while reducing energy use and recovering hydrochloric acid.
