ALEXANDRIA, Va., Oct. 6 -- Joe Bichel and Stephen Schaaf, both of Calgary, Canada, have developed a method for recovering purified sodium bicarbonate.

According to the abstract released by the U.S. Patent & Trademark Office: "A process for recovering sodium bicarbonate and ammonium sulfate from a sodium sulfate solution. The sodium sulfate solution can be pure or contain other compounds such as sodium sulfite, carbonate, chloride, fluoride, nitrate and nitrite as would be the case if the sodium sulfate solution were derived from a sodium bicarbonate flue gas purification process. Carbon ...
