Latest Patents

Narasimba M Rao holds a patent for a process aimed at the removal of primarily iron oxide deposits. This method is designed to recycle ferrous and ferric complexing agents, resulting in low volume, highly concentrated iron wastes for disposal. The process combines the use of citric acid or citric acid-tannin complexing agents with erythorbic acid reducing agents to effectively clean corroded surfaces. The recovery of both complexing and reducing agents is achieved by contacting the spent cleaning solution with strong acid cation exchange resins or chelating resins. These resins remove and retain iron species, releasing the chelating and reducing agents into the effluents. A concentrated iron waste stream is recovered by regenerating the resin beds with strong acids, such as HCl and H₂SO₄.
