Innovations in Air Pollution Control

摘要

Since the United States enacted Amendments to the Clean Air Act in 1977, mining and smelter operations around the world have been required to develop and implement new technologies to meet air quality regulatory requirements. Hydrometallurgy, acid gas plants, and high-heat bag houses are some of the more common technologies that were developed specifically to meet air quality regulatory requirements. Air quality regulations have continued to become more stringent and new pollutants are becoming regulated. Stricter SO_2 emission standards and toxic air compound regulations are being implemented around the globe, forcing further innovation or possible facility closures. Additionally, Greenhouse Gas regulations are being developed, mandating greater fuel efficiencies for mines and smelters. As the regulations continue to be promulgated, new technologies and methods of operation will need to be developed. Because new technologies are being developed, electronic air quality control resources that are currently being updated on a regular basis have been listed to aid in information transfer.
