With a total of 2 patents, her work focuses on the treatment of hazardous materials and the improvement of waste management processes.
Latest Patents
One of her latest patents is titled "Treatment of pit waste containing chromated copper arsenate." This chemical process addresses the treatment of pit waste contaminated with chromated copper arsenate (CCA). The process allows for the recovery of CCA for recycling, while ensuring that the remaining solids are decontaminated for safe disposal. The method involves pulverizing pit wastes and reacting them with concentrated sulfuric or phosphoric acid. Approximately 60% to 70% of the CCA is leached out, and the acid-treated mixture is then centrifuged or filtered to separate liquids from solids. The liquids are recycled for reuse in the CCA process, while the CCA-bearing solids undergo further treatment in a heated digester.
Another significant patent is the "Method for removing and decomposing hydrocarbon compounds from water." This invention provides a method and apparatus for the removal and safe disposal of trace quantities of toxic or carcinogenic hydrocarbon compounds from wastewater. The process converts these harmful compounds into less noxious, readily disposable substances. The wastewater is first mixed with rehydratable alumina, allowing the hydrocarbon pollutants to be absorbed. The compounds are then filtered out, and the remaining water is safely drained. The alumina containing the toxic compounds is reactivated through heating for reuse, while non-reusable alumina is digested in sulfuric acid to decompose any remaining toxic substances.
