NO_x Removal from Simulated Marine Exhaust Gas by Wet Scrubbing Using NaClO Solution

Figure 13

The change of (a) NO_x removal efficiency and (b) NO_x concentration with the initial SO₂ concentration (gas flow is 1.25 L/min, inlet SO₂ concentration is 200–600 ppm, inlet NO_x concentration is 1000 ppm, NaClO concentration is 0.05 M, initial solution pH is 6, and solution temperature is 293 K; solid points refer to inlet NO_x concentrations and open points refer to outlet NO_x concentrations).
