ABSTRACT:
A reverse-jet scrubber apparatus and method for removing gaseous contaminants, such as sulfur dioxide, and particulate matter from a combustion gas stream, employing low energy and reduced amounts of scrubbing liquid, which apparatus comprises: an elongated conduit; and a plurality of jet-spray nozzles centrally disposed and spaced apart from each other in the conduit and adapted to spray under high pressure a caustic scrubbing liquid countercurrently into a high-velocity, combustion gas stream, to form separate spray scrubbing zones covering the cross-sectional area of the conduit, whereby a combustion gas stream is scrubbed and a clear gas stream is recovered downstream of the scrubbing zones.
