Latest Patents
One of Schrecengost's latest patents is titled "Control of mercury and other elemental metal emissions using reaction stabilization device." This invention involves injecting ammonia and optionally carbon monoxide into flue gas containing metals like mercury. The process occurs at temperatures ranging from 900°F to 1,450°F, allowing for the oxidation of these metals. The oxidized metals are then attracted to particulates in the flue gas, which are subsequently removed by devices such as electrostatic precipitators or baghouses. Another significant patent is the "Method to decrease emissions of nitrogen oxides and mercury through in-situ gasification of carbon/water slurries." This method utilizes a coal-water slurry to adjust the carbon-to-water ratio, enabling the formation of activated carbon that collects mercury chloride from the flue gas.
