Latest Patents

Warren's latest patents include a groundbreaking method for the stripping and recovery of dichromate in electrolytic chlorate systems. This process effectively removes dichromates from chlorate-rich solutions containing hypochlorite and dichromate ions produced by the electrolysis of brine. The dichromate is reduced in a two-stage process through the addition of ammonia under controlled conditions of pH and temperature, resulting in a mixed di- and trivalent chromium hydroxide that is precipitated from the solution and removed. This method provides an economical way to recover chromium from electrolytically produced chlorate solutions.

Another significant patent by Warren is the process for the production of sodium chlorate. This method involves the electrolysis of sodium chloride contaminated with sodium sulfate, ensuring that the sulfate concentration in the system remains below a pre-selected level. A portion of the mother liquor, remaining after crystallizing some of the sodium chlorate product, is selectively cooled to crystallize some of the sodium sulfate present in the liquor. This process establishes an acceptable 'steady-state' concentration of sulfate ion, preventing the harmful buildup of excess sulfate ions in the electrolytic system.
