  • Title: Flue gas treatment for SO2 removal with air-sparged hydrocyclone technology.
    Author: Bokotko RP, Hupka J, Miller JD.
    Journal: Environ Sci Technol; 2005 Feb 15; 39(4):1184-9. PubMed ID: 15773494.
    Abstract:
    Laboratory results from an initial study on the removal of SO2 from gas mixtures are reported using air-sparged hydrocyclone (ASH) technology. Tap water and alkaline solutions were used for absorption, and the influence of gas flow rate, water flow rate, and length of the ASH unit were investigated. The research results indicate thatthe air-sparged hydrocyclone can be used as a highly efficient absorber for SO2 emissions. The ASH allows for 97% SO2 removal using water alone for sulfur dioxide content in the gas phase of 5 g/m3. All SO2 is removed in weakly alkaline solution (0.01 mol NaOH/dm3).
