A purification composition, comprising 50-60% by weight of ash and 40-50% by weight of liquid. A method for producing the purification composition, comprising: measuring an amount of ash, combining the ash and liquid, wherein an amount of the liquid is based on the amount of the ash, adjusting a temperature of the combination of the ash and the liquid by adjusting a temperature of the liquid and mixing the ash and the liquid. A method for purifying a flue gas by the purification composition, comprising: combining the purification composition and vapour to form a chute, adding the chute to the flue gas, adding the purification composition to the flue gas and over-pressuring the flue gas and adding more of the purification composition to the flue gas and under-pressuring the flue gas.

The invention includes systems, methods, compositions, and processes for designing, manufacturing, and utilizing carbon dioxide-sequestering substrates that can fully or partially replace natural sand in coastal engineering applications. These engineered substrates can offset demand for scarce native sand resources, while also effecting the conversion of gaseous carbon dioxide to dissolved or solid-phase products thereby offsetting impacts of anthropogenic climate change.

Systems and apparatuses for neutralizing acidic compounds in flue gases emitted from a heat recovery coke oven. A representative system includes a spray dry absorber having a barrel that includes a plurality of wall plates that form sidewalls of the barrel. The wall plates include a steel plate and a corrosion resistant alloy cladded to the steel plate and the wall plates are oriented such that the corrosion resistant alloy faces toward and is in fluid communication with an interior area of the barrel. The alloy is resistant to corrosion caused by the acidic compounds in the flue gas and can prevent the steel plate from being corroded by these acidic compounds.
