Simultaneous wet absorption of SO2 and NOX with mixed Na2SO3 and (NH4)2SO3: Effects of mass concentration ratio and pH

Wet flue gas desulfurization is considered as one of the most effective methods for the simultaneous removal of NOX and SO2 in the flue gas. To investigate the absorption performance of NOX and SO2 with the absorbents of Na2SO3 and (NH4)2SO3 and study the controlling factors of the process, the sulfite-based mixed absorbents with different mass concentration ratios of Na2SO3 to (NH4)2SO3 are employed for the gas removal in a bubble absorber. The...
