The desulfurization sludge was collected from four coal-fired power plants located in China's Shandong Province (two power plants, A and B) and inner Mongolia (two power plants, C and D). The detailed configuration and the air pollution control devices (APCDs) are summarized in Table 1 .
The reliable and accurate determination of corrosive anions at sub- to low-μg/L levels is a challenging analytical problem. In this manuscript, a simultaneous determination method of cations and anions in power plant water samples was established by large volume injection ion chromatography. The ana …
The energy consumption of FO integrated with MD can be further compensated by utilizing the waste heat of the coal-fired power plant. Consequently, FO integrated with MD can be more attractive in treating and reusing a variety of wastewater generated from fossil-fuel power plants by coupling it with low-grade waste heat.
Introduction. Flue gas desulfurization (FGD) is the removal process of sulfur dioxide (SO2) from flue gases. Sulfur dioxide in gases is produced by the combustion of fossil fuels and many industrial processes such as gasoline refining as well as cement, paper, glass, steel, iron and copper production.
