Patricia R Lewis is a notable inventor based in Livermore, CA (US). She has made significant contributions to the field of waste management through her innovative patents. With a total of 4 patents, her work focuses on the destruction of organic waste using advanced chemical processes.

Latest Patents

One of her latest patents is an integrated system for the destruction of organics by hydrolysis. This system comprises a hydrolysis step at moderate temperature and pressure, followed by direct chemical oxidation using peroxydisulfate. It is designed to quantitatively destroy volatile or water-insoluble halogenated organic solvents, contaminated soils and sludges, and the organic component of mixed waste. The hydrolysis step results in a substantially single phase of less volatile, more water-soluble hydrolysis products, thus enabling the oxidation step to proceed rapidly and with minimal loss of organic substrate in the off-gas.

Another significant patent is the mediated electrochemical oxidation of organic wastes using a Co(III) mediator. This electrochemical cell operates with a Co(III) mediator and neutral pH anolyte, providing efficient destruction of organic and mixed wastes. The organic waste is concentrated in the anolyte reservoir, where the cobalt mediator oxidizes the organics and insoluble radioactive species, regenerating at the anode until all organics are converted to carbon dioxide and destroyed. The neutral electrolyte is non-corrosive, extending the lifetime of the cell and its components.
