Nitrogen oxide emissions are easier to control than sulfur dioxide emissions.

Question

Quizplus · Accepted Answer

Nitrogen oxide emissions are more difficult to control than sulfur dioxide emissions because they require more complex and costly reduction technologies and strategies, such as selective catalytic reduction (SCR) or selective non-catalytic reduction (SNCR), compared to the relatively simpler methods available for sulfur dioxide, like flue gas desulfurization (FGD).
