Abstract
A horizontal wet scrubbing apparatus and method for removing sulfur dioxide from hot flue gases. The apparatus has a horizontally disposed housing through which the hot flue gases are passed, and at least one liquid injection manifold vertically disposed therein and extending to adjacent a lower wall of the housing for directing an aqueous scrubbing medium parallel to the gas flow, and a flow deflection member adjacent to, and downstream from, the manifold. Aqueous scrubbing medium is collected in reservoirs at the lower wall of the housing and recycled to the injection manifolds. The method provides for injection of aqueous scrubbing medium parallel to the flue gas flow and deflection of the gases, following the injection, by use of packing or baffles to provide intimate contact of the scrubbing medium with the gaseous stream.
