Pollutants emission control regulations

These toxic components sometimes travel more than a thousand kilometers and cause problems in other places and, in some cases, in other countries. Therefore the problem of air pollution attracts worldwide attention. Among these, the coal-fired flue gas from thermal power plants has been recognized as one of the main sources of environmental pollution, because of its larger amount of 8 and N components. Now many countries are introducing stricter emission control regulations to solve the problem.

Ceria-based formulations are among the more active catalysts for soot oxidation either under Og or in a NOyOg atmosphere, which decreases the combustion temperature from above 600°C down to 320-350°C. These results are very important for fulfilling new regulations on pollutant emission control. Among the several physicochemical parameters that influence the overall activity, the redox capacity and the availability of surface active oxygen species are certainly the most important. 

Recent air pollution regulations limit the amount of volatile organic carbon (VOC) that can be discharged from wastewater treatment plants. Benzene is a particular case in which air emission controls are required if the concentration of benzene in the influent wastewater exceeds 10 mg/L. 

Pollutants and sludges extracted from CAA air emission control devices are subject to RCRA hazardous waste regulations if hazardous... 

Intentions by the EPA to more tightly regulate the emission of hazardous air pollutants through maximum-achievable-control-technology standards are briefly reported with reference to styrene emissions. The regulation would require that any facility that emits more than 100 tons of styrene annually, should retrofit with expensive ventilation equipment, and that a new facility of any size would have to install the same type of equipment. The composites industry considers this to be an expensive standard, which could put companies out of work. 

At the heart of the problem of relating improvements in air quality to reductions in pollutant emission is a reliable method of prediction. Only with such a method can there be rational planning for air pollution control through regulation of transportation, indirect sources, and stationary sources. Decision-makers need it as a tool and must specify it in their regulations. Otherwise, their administration of an air quality plan would be based on sheer guesswork tempered by political negotiation. 

Developing a pollution control system involves an engineering evaluation of several factors which encompass a complete system. These include investigation of the pollution source, determining the properties of the pollution emissions, design of the collection and transfer systems, selection of the control device, and dispersion of the exhaust to meet applicable regulations.
