Air Stripping and Emissions Control Technologies: Field Testing of Countercurrent Packings, Rotary Air Stripping, Catalytic Oxidation, and Adsorption Materials
Abstract
The objective of this activity was to field test innovative air stripping with emissions control technologies. The scale of the various components used in these tests was selected such that results would be useful for better predicting the performance of application-scale equipment. The goal of this effort was to provide managers and engineers with necessary information so that decisions relating to the application of this technology can proceed on a rational basis. Conventional countercurrent air stripping (with 4 different packing materials) were compared to a centrifugal contactor, also known as a rotary air stripper. Emissions control tests showed that the activity of the noble metal catalyst was lost before any useful abatement results were obtained. This loss in activity was attributed to poisoning by sulfur stripped from the groundwater. Control of the emissions by activated carbon was achieved. Significant quantities of lighter hydrocarbons were noted in the stripper effluent that were not effectively adsorbed by the carbon. No generally useful results were obtained for control of emissions by molecular sieves.
