Abstract
A treatment system for process exhaust streams containing NOx. The system includes a plurality of sequential scrubbing assemblies that collectively receive and contact a process exhaust stream containing NOx and a water stream to produce a product exhaust stream with a concentration of NOx that is below a determined threshold value. The removed NOx forms a portion of a system waste liquid stream that includes a majority of the NOx removed from the process exhaust stream.
