Abstract

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.
