Flue Gas
Flue gas is considered an air pollutant which refers to the combustion of exhaust gases produced by various industries. The major component of the flue gas generated from fossil-fuel combustion is nitrogen and oxides of nitrogen, such as nitrogen oxide, nitrogen dioxide, and nitrogen xide. Flue gas contains around 10−25 % (v/v) of CO2 ...

Fathoming Filtration: Reducing Pollutants in Coal-Fired Power Plants
SO 2 levels in today's coal-fired power plants can be reduced by wFGD (wet flue gas desulphurisation) or spray dryer absorption (SDA) – for example, NOx by selective catalytic reduction (SCR) and mercury by coal washing. Individually, though, these are not enough and flue gases need further processing for proper reductions. Perhaps …

The fate of mercury in coal-fired power plants and the
The Hg concentrations in coal as fired in power plants in the Netherlands are low, 0.2 mg·kg−1 on average. After combustion the Hg is released partly (between 1 and 98%, on average 42%) in a gaseous phase, which is finally emitted into the air. The other part of the Hg, which remains in the ash is separated from the flue gases by electrostatic …

Process development of flue gas desulphurization
Zero emission of wastewater from coal-fired power plants (CFPPs) is one of the pathways for cleaner electricity production. It is expected that low-cost and reliable zero liquid discharge (ZLD) of flue gas desulphurization (FGD) wastewater will be achieved by applying the forced circulation multi-effect distillation and crystallization (FC-MEDC) …

The characteristics of arsenic in Chinese coal-fired power plant flue
Coal-fired flue gas desulfurization (FGD) gypsum is one of the by-products generated in the process of removing sulfur dioxide using a limestone slurry. In 2016, 6.64 million tons of FGD gypsum was produced by thermal power generation and heating in Chinese large and medium-sized cities, and 80.6% of the gypsum was recycled [1] .

Membrane processes for carbon capture from coal-fired power plant flue
The coal-fired electric power sector contributes about 33% of CO 2 emitted by all the fossil fuel sources (coal, petroleum and natural gas) in the US [6]. Thus, it is amply obvious that cost-effective reduction of CO 2 emissions from the coal power plants will be the most important GHG reduction activity in the coming decades.
