    • Nitric oxides can be absorbed from gas mixtures containing nitric oxides (NO and NO.sub.2) and oxygen by absorption with aqueous solutions. According to the invention, the absorption is effected in bubble columns, superficial velocities of 2 to 30 cm/second being maintained. It is advantageous to connect several bubble columns in series such that the gas and absorption liquid pass in counter-current to one another. In this embodiment, considerably less counter-current stages are required to achieve a high degree of absorption of NO.sub.x than in the case of conventional processes. At superficial velocities of 10 to 30 cm/second, large bubbles of gas can rapidly form from the gas introduced and can interact with the absorption liquid only with difficulty. In this case, gas distributor devices are incorporated in the bubble column. Since NO.sub.2 is more readily absorbed than NO, it is advantageous to connect flow reactors, in which NO.sub.2 is formed from NO and O.sub.2, upstream of the bubble columns.
    • 一氧化氮可以通过含有硝酸氧化物(NO和NO2)的气体混合物和氧气通过水溶液吸收而吸收。 根据本发明,在气泡塔中实现吸收,保持2至30cm /秒的表观速度。 连接几个气泡塔是有利的,使得气体和吸收液体彼此逆流通过。 在该实施例中,与常规方法的情况相比,需要相当少的逆流阶段来实现高吸收NOx。 在10〜30cm /秒的表观速度下,气体可以从引入的气体迅速形成,并且难以与吸收液体相互作用。 在这种情况下,气体分配器装置结合在气泡塔中。 由于NO2比NO更容易吸收,因此连接流动反应器是有利的,其中NO 2由气泡塔上游的NO和O2形成。
