The process route of the project also chose the current international mainstream SCR denitrification technology. The flue gas of 3 landfill gas generator sets with a total power of about 2MW was collected into a flue gas denitrification system to treat NOX, and then discharged by the chimney. null. On this basis, in accordance with the characteristics of landfill gas, combined with actual working conditions and Hanlan’s years of practical experience, a special denitrification plan was developed for the high-power landfill gas unit of the project, and at the same time, it was selected and developed by Hebei Hanlan. The medium temperature denitration catalyst is designed to ensure the denitration efficiency.

In view of the particularity of landfill gas in Hebei Hanlan, the denitration catalyst is prone to excessive levels of heavy metals, halogens, sulfides, and siloxanes in the biogas, which may harm the performance of the catalyst or cause a second time due to too high combustible components in the flue gas. Burning, resulting in deactivation of the catalyst. For this reason, strict restrictions are imposed on the composition of the flue gas, which effectively avoids the loss and inconvenience caused to customers due to catalyst poisoning, thereby providing protection at multiple levels.

After commissioning, the Wanchun SCR denitrification system of the landfill gas generator set designed and manufactured by Hebei Hanlan is completed and the original flue gas parameters meet the design input conditions. After purification, the outlet nitrogen oxide (NOx) concentration is ≤120mg/Nm3 (15% oxygen content), meet the target emission value, and successfully pass the acceptance.
