Nitric Oxide Removal by Combined Ammonia and Fe(II)EDTA in a Packed Tower
Publication: Journal of Environmental Engineering
Volume 146, Issue 11
Abstract
To explore the effects of some operating conditions on NO removal efficiency in a packed tower, the denitration process was simulated in a laboratory-scale packed tower using an ammonia solution containing Fe(II) ethylene diaminetetraacetic [Fe(II)EDTA]. The effects of pH, NO concentration, Fe(II)EDTA concentration, concentration, and concentration on denitration efficiency were studied. The experimental conditions to get the best denitration efficiency are as follows: pH of the absorbed solution is 6.5, liquid/gas ratio is , and the appropriate concentration of Fe(II)EDTA and is 0.03 and , respectively. When the concentration of rises from 1,500 to , the removal efficiency of nitric oxide decreases slightly. The basic data obtained from results are in favor of the application of industrial desulfurization and denitration.
