With the promotion of people’s awareness of environmental protection and the promotion of renewable energy, biogas power generation in sewage plants has been widely used as a clean energy technology. However, biogas generators may produce nitrogen oxides (NOx) during operation, which will not only pollute the environment, but also affect human health.
Biogas produced by the anaerobic digestion process at sewage plants is a valuable renewable energy source that can be used to generate electricity and reduce dependence on fossil fuels. However, the problem of NOx emissions generated by biogas generators during combustion needs to be solved. The application of denitration technology is of great significance to realize the green and environmental protection of biogas power generation.
During the operation of the biogas generator set of sewage plant, a certain amount of nitrogen oxides (NOx) may be produced due to the high temperature generated by the combustion of biogas, which is the prerequisite for the formation of acid rain and photochemical smog. Therefore, controlling NOx emissions is the key to achieving the environmental goals of biogas generators. Denitration technology mainly includes selective catalytic reduction SCR and selective non-catalytic reduction SNCR. SCR technology reduces NOx to nitrogen and water through catalyst and ammonia or urea. SCR denitrification technology is used by all walks of life with more than 98% high denitrification efficiency and low ammonia escape rate. Under the premise of reasonable design, denitrification equipment is installed and debuted to ensure stable operation of the system.
Our implementation case:
Denitrification of tail gas of an industrial sewage biogas generator set in Zhejiang Province
Unit brand: Shengdong 700KW
Unit model: Z12V1190ZLD
Biogas category: Biogas generator set *3 groups
NOx3000mg/Nm³ down to 150mg/Nm³
The biogas generator set of a sewage plant in Zhejiang Province adopted our SCR denitration technology, which successfully reduced the NOx emission below the national ultra-low emission standard and improved the biogas power generation efficiency.
Denitrification of biogas power generation in sewage plants is an important measure to achieve green energy development. By adopting our advanced denitrification technology, we can not only reduce NOx emissions, improve environmental quality, but also further enhance the economic and social benefits of biogas generators.
