Latest Patents

Feldmann holds a patent for the "Production of high strength hydrochloric acid from calcium chloride feed streams by crystallization." This patent describes a method for producing calcium sulfate solid crystals and hydrochloric acid (HCl) from a calcium chloride solution. The process involves feeding a continuous stirred-tank reactor with a calcium chloride solution, sulfuric acid, and water. The mixture is then maintained at a temperature of less than about 70° C., converting the solution into HCl and calcium sulfate solid crystals. This method can be particularly useful for regenerating HCl from calcium chloride solutions generated in the metallurgical industry when processing calcium-bearing ores for recovering metals like rare earth elements.
