A tool (TEAP) to evaluate in real-time and operational mode the air quality produced by industrial plants (power plants also) has been developed based on the third generation of air quality modelling systems. The system uses the non-hydrostatic mesoscale meteorological model MM5 (PSU/NCAR, USA) and the air quality modelling system (transport and chemistry) CMAQ (Community Multiscale Air Quality...

Accurate estimations of power plant NOx emissions can be made with OMI data. Exponentially-Modified Gaussian fit needs multi-annual OMI averages. Box Model fit requires seasonal OMI averages for accurate estimates. Lifetimes are dominated by a mixed lifetime that does not represent chemical lifetime. Continuous Emission Monitoring System (CEMS) provides an excellent emissions test bed. CEMS Emi...

During the eighties the city of Rijeka was one of the most polluted cities in Croatia with sulphur dioxide due to high emission of this pollutant from industrial plants. In mid-eighties, annual means of SO2 exceeded 100 micrograms/m3 in the city centre, in the Bakar Bay area varied between 70-80 micrograms/m3, while in the suburban residential area they were up to 40 micrograms/m3. In 1995 annu...

China is the largest contributor to global atmospheric mercury (Hg), and accurate emission inventories in China are needed to reduce large gaps existing in global Hg mass balance estimates and assess Hg effects on various ecosystems. The China Atmospheric Mercury Emission (CAME) model was developed in this study using probabilistic emission factors generated from abundant on-site measurements a...

This paper proposes the exchange market algorithm (EMA) to solve the combined economic and emission dispatch (CEED) problems in thermal power plants. The EMA is a new, robust and efficient algorithm to exploit the global optimum point in optimization problems. Existence of two seeking operators in EMA provides a high ability in exploiting global optimum point. In order to show the capabilities ...

The carbon dioxide fixation by microalgae has several merits such as the COz recovery and the production of useful chemicals. Since the flue gas from a industry has some unfavorable conditions such a s high CQ concentration and toxic chemicals like SO., NO, contained in flue gas for the cultivation of m s t microalgae, it is important to apply a suitable strain of microalgae for the fixation of...

The identities and physicochemical characteristics of potentially carcinogenic species emitted to the atmosphere by fossil-fueled power plants are presented and discussed. It is pointed out that many so-called carcinogens are preferentially concentrated on the surface of respirable fly ash particles thus enabling them to come into intimate contact with lung tissues when inhaled. Relatively litt...

Electricity production accounts for around 40% of global energy-related CO2 emissions and it is expected that the electricity demand increases to twice the current level in 2050. Therefore it is necessary to invest in low-carbon thermal power plants, nuclear and renewable energy for realizing low-carbon economy. These policies may require a large amount of investment costs, and additionally, th...

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 ...
