Latest Patents
Helmstetter's latest patents showcase his expertise and innovative thinking. One of his notable inventions is the "Salt handling apparatus for a hypochlorous acid reactor." This apparatus effectively separates solid salt by-products from the gaseous hypohalogenated acid produced in the reactor. It is designed to separate particles ranging in size from about 0.5 to about 50 microns. The reactor operates by mixing an aqueous alkali metal hydroxide with a gaseous halogen to generate the hypohalogenated acid product and solid salt by-product, which are then discharged into the separation apparatus.
Another significant patent is the "Process for producing low aluminum membrane cell feedbrine." This process controls the concentration of aluminum in the brine of a membrane chlor-alkali cell. It involves digesting calcium carbonate settler solids in the calcium chloride flow stream by adding an inorganic mineral acid to adjust the pH to about 2.0 to about 3.0. This adjustment solubilizes the aluminum in the brine, which is then reprecipitated onto carrier particles before being removed through filtration or centrifugation.
