Title: F Weldon Meadus: Innovator in Soil Remediation and Coal Processing
Introduction
F Weldon Meadus, an accomplished inventor based in Ottawa, Canada, has made significant contributions to the fields of soil remediation and coal processing. With a total of four patents to his name, Meadus has demonstrated a steadfast commitment to innovation and environmental sustainability.
Latest Patents
Among his notable inventions, the process for soil remediation stands out. This invention focuses on the removal of contaminants, such as hydrocarbons, from soil by contacting the polluted substance with a suitable solvent, while utilizing a bridging liquid that is immiscible with that solvent. Balancing the amount of bridging liquid and the degree of agitation allows for the control of particle size in the resulting contaminant- and solvent-free soil agglomerates.
Additionally, Meadus has developed a method for incorporating a coprocessing additive into coal and oil agglomerates. This process involves adding iron sulfate in an aqueous wash solution to coal agglomerates post-ash separation. The method ensures efficient dispersion of iron sulfate throughout the agglomerate matrix, promoting strong adsorption of Fe ions onto coal surfaces without compromising the integrity of the agglomerates. This innovative approach has been shown to enhance the lowest temperature for coke formation during coprocessing.
