1. A method for the partial removal of contaminants from a process gas stream comprising the steps of:

  • conveying a stream of untreated process gas through an inlet of a scrubber into a scrubbing zone of the scrubber,dividing the gas stream at the scrubber inlet free of any physical obstruction in the scrubber extending the length of the scrubber from the inlet to an outlet into a plurality of process gas streams partitioned from one another,feeding ozone into contact with selected ones of the partitioned gas streams in the scrubber to oxidize contaminants in the partitioned gas streams,removing the oxidized contaminants from the selected partitioned gas stream, andrecombining the selected partitioned gas streams substantially free of contaminants with the remaining partitioned gas streams containing contaminants.
