Simultaneous removal of multi-pollutants from flue gas by a vaporized composite absorbent

Regeneration/Optimization of Activated Carbon Monolith in Simultaneous SO2/NOx Removal from Flue Gas

“…The performance of the RE-SO 2 and RE-NO x responses in the various interactions were similar and the surface plot proved the similarities. Typically, simultaneous SO 2 /NO x removal was carried out by using biased concentrations in ratio > 3:1, i.e., simulated gas composition in favor of SO 2 [4,5,39,40]. In the current research, the ratio of the SO 2 :NO x was about 1:1 in accordance with the flue gas from a typical coal-fired power station.…”

A novel low‐temperature NO removal approach with •OH from catalytic decomposition of H2O2 over La1‐xCaxFeO3 oxides

“…1. The compressed gases in cylinders were controlled by valves (1). The gas flow rate of air, N 2 , and 3000 ppm NO/N 2 was measured by mass flow controllers (2).…”

“…NO x as the precursors forming photochemical smog has brought about serious environmental problems which threaten human health. Because the coal‐fired combustion process is one of NO x ‐emitted sources, many environmental regulations have been issued by the Chinese government to control the emission of NO x from flue gas . Conventional methods like selective non‐catalytic reduction (SNCR) and selective catalytic reduction (SCR) have been widely used in power plants.…”

“…Because the coal-fired combustion process is one of NO x -emitted sources, many environmental regulations have been issued by the Chinese government to control the emission of NO x from flue gas. 1 Conventional methods like selective non-catalytic reduction (SNCR) and selective catalytic reduction (SCR) have been widely used in power plants. The activated temperatures of conventional methods are usually >300 ∘ C. 2 However, the flue gas temperature in industrial boilers is lower than 200 ∘ C and thus, the conventional NO removal approaches cannot be applied in industrial boilers.…”

Effects of experimental parameters on simultaneous removal of SO2 and NO by VUV/H2O2 advanced oxidation process in a pilot‐scale photochemical spraying tower

“…Hao et al . proposed and developed a series of integrated methods of gas oxidation with wet absorption for simultaneous removal of SO 2 and NO, and a number of complex oxidants were studied, such as Fenton/PAA/NaClO, NaClO 2 /NaBr, UV/vaporized H 2 O 2, H 2 O 2 /Na 2 S 2 O 8, H 2 O 2 /NaClO 2 etc. Moreover, advanced wet oxidation processes have also been extensively researched and developed.…”
