Dust is the major potential air pollutant from briquet plants. Other possible air pollutants--droplets, gases, and odors--are less likely to be major problems. An air pollution control program for a briquet plant would involve monitoring of dust emissions at the source, such as stack or unit operation sites. Emissions also should be determined for the surrounding area as well as within the plant boundary. Furthermore, terrain and climatological effects on air pollution should be evaluated. Simple, inexpensive instruments and methods available for dust-load measurement include the dust- fall bucket, high-volume sampler, tape sampler, stack sampling equipment, and ringelmann smoke chart. Conventional equipment, such as scrubbers, cyclones, and bag filters, is available to control emissions from unit operations. Control of air pollution in briquet manufacture has the benefits of a clean plant, healthful working conditions, and good employee morale.
