Abstract
A combined removal system for separating carbon dioxide and sulfur oxide gases from furnace flue gases employs a single vessel having two chambers. The chambers are separated by a series of baffles and drains. The lower, primary chamber contains reagent and a delivery system for removing sulfur oxides (SO.sub.2 and SO.sub.3) from the flue gases. The upper, secondary chamber has a reagent, typically an amine solution, for removing carbon dioxide from the flue gases. The baffles and drains permit the flue gases to rise from the primary chamber into the secondary chamber, while collecting the amine solution which is used to trap the carbon dioxide. Alternatively, the primary and secondary chambers may be separated by a horizontal segment or a combination of horizontal and vertical sections.
