Abstract
An integrated device for removal of both liquid-containing droplets and pollutants from a gas stream includes a plurality of passageways and a plurality of exposed surface portions, different ones of the surface portions disposed along different ones of the plurality of passageways. The plurality of passageways include an inlet and an outlet for the flow of a gas stream therethrough, wherein each passageway includes at least one segment configured to perturb the flow of at least a portion of the gas stream between the inlet and the outlet. Such gas perturbation enhances gas stream contact with the exposed surfaces. Portions of the exposed surfaces comprise a sorbent-polymer-composite material adapted for contact conversion of sulfur oxides to sulfuric acid droplets. The exposed surfaces are disposed to enhance the removal of liquid-containing droplets and contact conversion of sulfur oxides to sulfuric acid droplets.
