Latest Patents

One of his latest patents is titled "Separation/recovery of ammonium salts via electrodialytic water splitting." This invention presents an improved process for generating salts of volatile acids and/or bases from a salt stream. The process involves treating a salt solution in a two or three compartment electrodialytic water splitter, where the acid formed is neutralized by adding the volatile base directly to the acid loop. This method enhances the efficiency of the membranes and the cell stack by minimizing acid concentration.

Another significant patent is the "Method to produce sodium citrate using electrodialysis." This invention outlines a method and apparatus for electrodialytically treating citric acid to produce sodium citrate. The process allows for the introduction of a cation into the solution via a donor salt solution, such as NaCl or KCl, without compromising the purity of the final product. The apparatus consists of a three-compartment cell with adjacent anion selective membranes to facilitate a cation substitution reaction.
