Venturi Scrubbers

Wet Approach Venturi Scrubber

Ducon Venturi scrubber is used to remove sub-micron particles from flue gas in a wet process utilizing high pressure. This unit features a wetted wall inlet which eliminates wet-dry line build-up and permits direct recycle of high-solids liquid. Scrubbing liquid is distributed over a weir or shelf - no spray nozzles are used. The Venturi is teamed with a mist eliminator for efficient entrainment separation.
