Air pollution is a major concern worldwide with human activities being the main contributor and causing serious health impacts. The present study was designed to monitor amount of gaseous pollutants (CO2, CO, SO2, NOX) total suspended particulates (TSP) from different industrial boiler’s exhaust using three fuel types (coal, natural gas heavy furnace oil/diesel). These five parameters were meas...

This work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for the control of SO2 and NOx emission in an Iranian steam power plant. The percent of fuel oil desulphurization was estimated from the SO2 emissions standards for power plants. Based on two different scenarios according to (I) European and (II) Iranian standards, the design and s...

Industrial agglomeration is a major source of regional economic development and the main pattern enterprises employ after having developed to certain stage. also affects emissions air pollutants in production. Based on provincial panel data for China from 2006 2019, this paper introduces full generalized least squares (FGLS) econometrics model. By considering spatial correlation, potential endo...

This study evaluates the effect of emission reductions at two coal-fired power plants in northwestern Colorado on a nearby wilderness area. Control equipment was installed at both plants during 1999-2004 to reduce SO2 and NOx emissions. One challenge was separating the effects of local from regional emissions, which also declined during the study period. The long-term datasets examined confirm ...

OBJECTIVE To examine associations between ambient air pollutants and respiratory outcomes among schoolchildren in Durban, South Africa. METHODS Primary schools from within each of seven communities in two regions of Durban (the highly industrialised south compared with the non-industrial north) were selected. Children from randomly selected grade 4 classrooms were invited to participate. Stan...

In urban areas, emissions of air pollutants by anthropogenic processes such as traffic, industry, power plants and domestic heating systems are the main sources of pollution (Fenger, 1999). The massive growth in road traffic and in the use of fossil fuels during the last decades has changed the composition of urban air, increasing the frequency of pollution episodes and the number of cities exp...

Measurements of gaseous SO2, NO, NO2, H2S, O3, NH3 and VOCs, in Kuwait city using IVL passive sampler technology, were obtained on monthly basis during the period from March 2011 to February 2012 at 10 locations. The results of this study reveal that those compounds had low concentrations compared to Kuwait Environment Public Authority standards for residential areas. It is found that nitrogen ...

Air quality policy to decrease fine particulate matter mass concentrations (PM2.5) in the US has mainly targeted sulfate aerosol through controls on sulfur dioxide (SO2) emissions. Organic aerosol (OA) instead of sulfate is now the dominant component of total PM2.5. Long-term surface observations (1991–2013) in the Southeast US in summer show parallel decreases in sulfate (2.8%–4.0% a ) and OA ...

Mn-Co-based catalysts were loaded to ceramic filters element by impregnation for the coprocessing of dust and nitrogen oxide (NOx) in flue gas. The influence Mn/Co ratio loading on catalytic performance was investigated. filter with a molar 2/1 can achieve 99% NO conversion selective reduction NOx NH3 (NH3-SCR) temperature range 100−180 °C, but its resistance H2O relatively poor. modified PTFE ...

Coal-fired power plants in the United States may have to reduce their mercury emissions by up to 90% by 2007 2009 due to proposed regulations that could affect up to 1,100 utility boilers. Air pollution control system components such as electrostatic precipitators, baghouses, NOx reduction catalysts, SO2 scrubbers, and their various configurations in utility applications significantly impact me...
