摘要： The present disclosure relates to a flue gas treatment system (e.g. a multi-pollutant flue gas treatment system) for removal of greenhouse gases such as SO 2 , NO, NO 2 , H 2 S, HCl, water and CO 2 as well as heavy metals (e.g. mercury, arsenic, bismuth, cadmium, lead and/or selenium) from the flue gases of fossil-fueled utility and industrial plants by reacting the raw flue gas, firstly, with chlorine in a gas-phase oxidation reaction and recovering the resulting products as marketable products, and then, secondly, treating the cleaned gas, which includes CO 2 , with a Sabatier reaction to produce a hydrocarbon fuel (e.g. methane). The system also includes an electrolytic unit for electrolyzing HCl to produce hydrogen gas for the Sabatier reaction as well as chlorine gas, which may then be recycled into the reactor.

摘要： The present invention is directed to a process for removing gas phase nitrogen-based compounds by absorption into a liquid stream. The absorbed nitrogen-based compound is reacted with an acid to produce a nitrogen-based product. The nitrogen-based compound, the acid, and the resulting nitrogen-based product may be organic compounds, i.e. compounds derived from animal matter or plant matter. The nitrogen-based product may be a fertilizer, such as ammonium acetate or ammonium citrate that may be certified as organic. Processes are also described for removing nitrogen-based compounds from a liquid stream to produce a nitrogen-based product, including organic fertilizers. One process includes producing cavitation bubbles into which a liquid phase nitrogen-based compound is stripped, followed by absorption to produce a nitrogen-based product. Another process includes the use of a degassing membrane to remove a liquid phase nitrogen-based compound that is degassed to produce a nitrogen-based product, including organic fertilizers.

摘要： An aftertreatment system comprises an aftertreatment component. An outlet sensor is positioned downstream of the aftertreatment component. A controller is communicatively coupled to the outlet sensor. The controller is configured to interpret an outlet signal from the outlet sensor. The outlet signal is indicative of a performance of the aftertreatment component. The controller determines if the aftertreatment component has deactivated. In response to determining that the aftertreatment component has deactivated, the controller provides a catalyst active material to at least a portion of the aftertreatment component. The catalyst active material coats at least the portion of the aftertreatment component so as to remanufacture the aftertreatment component.
