In order to investigate the characteristics of the reaction between ammonium sulfite, the main desulfurizing solution, and the flue-gas-contained sulfur dioxide during the process of ammonia-based WFGD (wet flue gas desulfurization) in a power plant, the gas-liquid absorption reaction between...

Promoting the nitrogen oxide (NOx) absorption step is the major challenge for simultaneous removal of sulfur dioxide (SO2) and NOx in wet flue gas desulfurization. This paper studied NOx absorption and absorption product formation in limestone slurry. The effect of CaCO3 concentration, NOx...
