A wet-dust collection system that uses foam rather than liquid droplets was developed to remove environmental pollutants from gases emitted from stationary sources. Operational conditions for the formation of a stable foam layer in the dust collector were identified. Over 99.9% of gas containing test powder could be removed when the gas was passed through the system. In absorption experiments on gaseous SO2 with H2O2 as the reactive absorbent, an absorption rate of >99.1% was obtained using the proposed system. Furthermore, in the absence of H2O2 and using a surfactant solution instead of only water, a higher absorption rate of SO2 was achieved with the formation of a foam layer.
