Abstract

Contemplated configurations and methods for flue gas treatment comprise a quench section and a scrubbing section that are configured and operated to avoid net condensation of water from the quenched flue gas in the scrubbing section. Consequently, the active agent in the scrubbing medium can be maintained at high concentration and will so allow continuous removal of SOX and NOX to very low concentrations. Moreover, as the scrubbing medium is not diluted by condensate, loss of active agent can be substantially reduced. Especially preferred systems will reduce SO2 concentrations in flue gas to less than 5 ppm, and more typically less than 3 ppm while substantially reducing water and reagent consumption.
