Title: Colin G Grieves: Innovator in Oil Shale Processing
Introduction
Colin G Grieves is a notable inventor based in Oswego, IL (US). He has made significant contributions to the field of oil shale processing, holding 2 patents that focus on innovative methods for retorting oil shale and purifying the resulting retort water. His work has implications for both environmental sustainability and energy production.
Latest Patents
One of Grieves' latest patents is centered around an oil shale retorting and retort water purification process. This process involves retorting raw oil shale in either an in situ underground retort or an above-ground retort. The goal is to liberate shale oil, light hydrocarbon gases, and oil shale retort water. The retort water is then separated from the shale oil and gases using a sump, fractionator, or quench tower, followed by an API oil/water separator. After separation, the retort water undergoes steam stripping, carbon adsorption, and biological treatment. This treatment can involve granular carbon adsorbers followed by activated sludge treatment or activated sludge containing powdered activated carbon. The purified retort water can be utilized in various oil shale processes, including dedusting, scrubbing, spent shale moistening, backfilling, in situ feed gas injection, and pulsed combustion.
