Title: Innovations by Robert Mitchell Davis in Oil Extraction
Introduction
Robert Mitchell Davis is an accomplished inventor based in Ft. Worth, TX (US). He is known for his innovative approach to environmental remediation, particularly in the field of oil extraction from contaminated soil. His work has significant implications for both environmental protection and resource recovery.
Latest Patents
Davis holds a patent for a method of extracting oil from oil-contaminated soil. This method involves contacting the contaminated soil, which contains 2 to 5 wt. % oil, with a solvent while applying sonic energy in the frequency range of 0.5 to 2.0 kHz. The process begins with mixing the solvent with the oil-contaminated soil to create a slurry. The slurry is then passed through a shaker screen to remove larger soil particles. The smaller soil particles are introduced into a vertically disposed acoustic chamber, where fresh solvent is injected from the bottom. The upward flow of solvent allows the oil to be displaced from the soil particles without cavitation. The result is substantially oil-free soil, which can be safely spread over land for farming. This method can also be applied to oily sludge and oil-based drill cuttings.
Career Highlights
Davis is currently employed at Mobil Oil Corporation, where he continues to contribute to advancements in oil extraction technologies. His innovative methods not only enhance oil recovery but also promote environmental sustainability.
