摘要:

AbstractTwo new processes that can each simultaneously remove sulfur dioxide (SO2) and nitrogen oxides (NOx) from flue gas by wet scrubbing with a liquor that contains an SO2‐removal agent and a metal chelate for NOxremoval are described. They are similar, except for different by‐products. In both, the spent scrubbing liquor is regenerated with respect to sulfur by an electrodialysis stack employing cation‐ and anion‐selective membranes. Sulfate salts are produced as by‐products. Experimentally, the liquor has been regenerated with respect to NOxremoval ability by holding it at elevated temperature, but the mechanism is not well u

摘要:

AbstractLarge, permanent buildings that are constructed of prestressed concrete, can withstand hurricane‐force wind loadings, and have extremely long lives can be used for long‐term storage of hazardous wastes. The buildings protect against seepage of leachate into soils and ground waters, emissions of volatiles, and contact of wastes with precipitation. Materials stored within the buildings would be available when technology and economics make recycling feasible. Hazardous wastes would be stored almost 10 feet (3.05 m) above land surface in a building designed for sub‐floor, walk‐through inspections for leaks. The proposed buildings can be as large as 250 feet (76.2 m) on a side and 70 feet (21.3 m) high and can support 9,000 pounds (40,000 N) of waste loading per square foot (0.305 m) of floor area. Each building, which can be constructed at virtually any location, would hold enough hazardous wastes to provide millions of dollars of return from construction of each b

摘要:

AbstractThe Air and Energy Engineering Research Laboratory of the U.S. Environmental Protection Agency (U.S. EPA) conducts and sponsors research on technology to reduce or eliminate emissions of potentially toxic volatile organic compounds (VOCs) from industrial/commercial sources.The realization that indoor air environments, where humans spend the majority of their time, also contain significant levels of VOCs has led to a number of EPA‐sponsored studies on monitoring, modeling, and controlling these compounds. The purpose of this paper is twofold: to present an overview of the problem of indoor air pollution by VOCs and approaches to solving it, and to report the results of a study to determine the feasibility of carbon adsorption for control of VOCs in indoor ai

摘要:

AbstractSources for indoor radon including radon from soils and rock infiltrating the substructure of a home and radon from water usage, building materials, outside air, and burning natural gas are reviewed. It is generally accepted that radon from soils and rock is the principal source for indoor radon. Correlations between indoor radon levels and soil characteristics are discussed for six areas in New York State. These results indicate that soils can be characterized for radon availability and transport into homes by a combination of soil parameters including the source strength (soil radium concentration or soil‐gas radon concentration), soil permeability for gas flow and, depth of soils to bedrock or water tabl

摘要:

AbstractIncreased interest in energy conservation, changes in airtightness, appliance design and building materials, along with fuel switching, have all combined to potentially raise the level of pollutants in the indoor environment, resulting in increased concern for indoor air quality.
