Holzer in his studies on wet separation of fine dusts and aerosols had listed the efficiencies of the basic five wet scrubbers from packed bed scrubbing tower to high pressure venturi scrubber, where the maximum efficiencies of these scrubbers fall between 42% and 95.6% for a mean particle size of 1.5 μm [43]. Thus the present novel wet ...

The objective of this work was to develop a novel wet-scrubbing process using Fe(vi) for the simultaneous removal of gaseous NO and SO2. The oxidation of SO2 and NO with Fe(vi) was studied in aqueous solution at alkaline pH (9.0–11.0). A stoichiometric molar ratio for NO and SO2 oxidation with Fe(vi) was det

A variety of dust control methods are often applied in coal mines, among which the application of wet scrubbers has proven to be an efficient technology for the removal of dust in airstreams, rather than diluting or confining the dust. In this paper, a wet scrubber design was developed. Based on a self-designed experimental test platform, …

An interesting alternative to this is offered by the fine screens marketed by various suppliers. These systems differ greatly from conventional wet screening machines. Astonishingly, these screening machines achieve higher selectivity in the fine particle range of 80 % < 75 μm than conventional hydrocyclones can.

For ammonia treatment in emissions, wet scrubbing is used. In acid scrubbing, a strong acid is added to the scrubbing liquid to react with the ammonia and to produce an ammonium salt, which can be safely discharged to a drain or wastewater treatment plant or sold as a liquid or solid fertilizer.

The focus of wet scrubbing is to choose an appropriate scrubbing liquid. In this study, methyl mercaptan (CH 3 SH) was selected as a representative hydrophobic organic odorant for treatment by wet scrubbing using several types of scrubbing solution: ethanol (C 2 H 5 OH), lead acetate ((CH 3 COO) 2 Pb), sodium hypochlorite (NaClO), …
