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 ...

and model’s scores The RMSE improvement presented in the abstract corresponds to the RMSE on stations, given in Section 4. We agree that the model’s performance cannot be summarized by this mild improvement, and we should insist more on the better representation of the spatial variability. As the reviewer states, the results for NO in terms of total RMSE are “surprisingly low” when given in the...

Abstract. Ships are an important source of SO2 and NOx, which key parameters air quality. Monitoring ship emissions is usually carried out using in situ instruments on land, depend favourable wind conditions to transport the emitted substances measurement site. Remote sensing techniques such as long-path differential optical absorption spectroscopy (LP-DOAS) measurements can supplement those me...

There are many industrial pollutants produced from coal fired power generation plants. Recent legislation is pushing to reduce these emissions. Greenhouse gasses as well as nitrous oxides (NOX) and sulfur dioxide (SO2) are the targeted pollutants. Governmental legislation outlined by Environmental Protection Agency (EPA) through its Maximum Achievable Control Technology (MACT) guideline is a ma...

Pollutant emissions into the atmosphere derived from port activities can be transported to surrounding regions and cities depending on wind speed direction, having an impact air quality. In this research, of atmospheric pollutants (NOx, CO, NMHCs, CO2, SO2, TSP, PM2.5 PM10) were estimated for: tanks, container, roll-on/roll-off (RO-RO), bulk carriers general cargo ships, using emission factors ...

Selective catalytic reduction of NOx with NH3 (NH3-SCR) has been widely investigated to reduce NOx emissions from combustion processes, which cause environmental challenges. However, most of the current work on NOx reduction has focused on using feed gas without CO2 or containing small amounts of CO2. In the future, oxy-fuel combustion will play an important role for power generation, and this ...

awma.org july 2008 em 29 The Clean Air Interstate Rule (CAIR) will further reduce regional emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx), thus reducing fine particulate matter (PM2.5) and ground-level ozone pollution in the eastern United States. The U.S. Environmental Protection Agency (EPA) estimates that CAIR will provide the largest benefits of any Clean Air Act rule issued in...

this work presents a simulation approach to the design and economic evaluation of fuel oil hydrotreating processes for control of so2 and nox emission in an iranian steam power plant. minimum amount of required fuel oil desulphurization was calculated from the limit of so2 emissions of power plants in two different scenarios based on (i) european and (ii) iranian so2 emission standards. based o...
