Control of Nitrogen Oxides
45 Nitrogen oxides from fuel combustion are an important contributor to air pollution.
46 Wet scrubbing,particularly with an alkaline scrubbing solution,will absorb SO2.
47 This method is ,however,not a feasible one to install only for NO2 control as in oil-stoichiometric combustion.
參考答案:二氧化氮的控制:
45 空气污染的很重要的原因是燃料中二氧化氮的释放
46 用碱液擦洗将能吸收二氧化硫
47 但是,这种方法对于仅装载在油化燃烧时对二氧化氮的控制是不可行的
