ABSTRACT:
The present invention provides for a method and apparatus for removing contaminants from a gas stream such as a flue gas stream from an industrial process. The process utilizes a prescrubber to contact the gas stream before the gas stream contacts an oxidizer in an oxidizer zone. The oxidized gas is then treated to either a first and second scrubber operation or just a single scrubber operation.
