1. Industry technology
Flue gas conditions are usually complex. In addition to nitrogen oxides, there are also many other substances such as sulfur dioxide, water, oxygen, dust, alkali metals, etc., and usually, denitrification must be coordinated with post-processing facilities such as desulfurization and dust removal. Therefore, according to Depending on the flue gas conditions in different industries, corresponding process routes are recommended.
1) Power plant
The power plant process route is relatively mature, including denitrification (300-420℃)-dust removal-wet desulfurization-wet power.
2) Coke oven
Dry or semi-dry desulfurization-dust removal-denitrification (180-250°C). The composition of coke oven flue gas is relatively complex. After the pre-dry and semi-dry desulfurization, the flue gas can be greatly purified, which is beneficial to improving the denitrification efficiency. Extend catalyst service life
