摘要
对硝酸吸收NOX进行了研究。结果表明:随着硝酸浓度的增大,NO吸收效率增加,NO2、NOX吸收效率先增加后降低;当NOX中NO2体积百分含量增加,其吸收效率增加;随进气浓度和液气比的增大NOX吸收效率增加;温度对吸收效率有较大影响。吸收过程中,温度越低,吸收效果越好。
The removing of nitrogen oxides by nitric acid absorption is studied. The results showed that with the increase of nitric acid concentration, NO absorption efficiency increases, NO2 and NOx. absorption efficiency increases first and decreases afterward. The overall absorption efficiency of NOx increased with the increase of the percentage of NO2 in NOx ; The absorption efficiency increased with the increase of gas concentration and liquid-gas flow ratio; the lower of temperature, the higher of absorption efficiency.
