Abstract |
Beryllium in almost all forms is known to have adverse effects upon human health. Approximately 300 domestic facilities either extract beryllium or manufacture beryllium-containing products. Beryllium extraction processes generate atmospheric emissions that include beryllium salts, acids, beryllium oxide, and other beryllium compounds in the form of dust, fume, or mist. Facilities engaged in processing beryllium-containing materials into finished products generate a more restricted range of emissions, including beryllium dust, beryllium oxide dust, and beryllium-containing dust and fume. Beryllium emissions can be controlled by the following classes of gas-cleaning equipment: prefilters, dry mechanical collectors, wet collectors, fabric filters, and high-efficiency particulate filters. The choice of specific control equipment is discussed in terms of process variables, effluent properties, and economics. (Modified author abstract) |
