Belyakov et al., Absorption and Adsorption Methods of Removing Fluorine Compounds from Industrial Gases[in Russian], TsINTIkhimneftemash, Moscow (1985). An important result of this treatment is the prediction of very low pressure drops, if an atomization system giving the “optimum” droplet size (rather than the larger droplet size produced by conventional pneumatic atomization) is used. Current practice suggests the use of simpler designs for both the particulate scrubber and SOg absorber. Scrubbers are devices that use a liquid (often water) to capture and remove pollutants.
