I understand you are currently looking for a chemical engineer to help with the design of a Venturi scrubber. The venturi scrubber is a highly efficient ing dgas cleanevice that uses liquid drop-lets to remove dust particles with diameters ranging between 0.1 and 300 µm and absorb gas-eous contaminants, such as SO. Dust laden gases enter the venturi and instantly make contact with the tangentially introduced scrubbing liquid swirling down the venturi’s converging walls.
