Catalytic Ceramic filter reduces emission of organic air pollutants from a cement plant

Proposed NESHAP (National Emissions Standard for Hazardous Air Pollutants) emission regulations in the US include the reduction of THC (Total HydroCarbons) and particulate matter to lower limits than what is required today. A single-step technology has been developed for dealing with both of these emissions. In the laboratory as well as at a US cement plant, results and knowledge from slip stream pilot tests have been gained. The promising results show it is possible to obtain very high removal efficiencies of the THC, especially organic HAPs (Hazardous Air Pollutants) and at the same time stay well below the dust emission limits.
