Description

Low Temperature SCR Denitration DeNOx technology


Where there is a combustion, there will generate NOx, and more NOx along with higher temperature. NOx is an outstanding gas pollution to the environment in China current days. Till 2020, China Govn. will strick on NOx emission under 150mg/Nm3 while we already successfully supplied less 100mg/Nm3 (can be adjusted under 50mg/Nm3) low temperature SCR DeNOx equipments to our customers. 

MER combining our environment equipment brother company (Handan Mingjing environment protection technology company--also one subsidiary of Dingzheng Group), China Lime Association, numberous design institutes and catalyst suppliers, we successfully design and manufacture high-efficient low temperature SCR DeNOx catalyst which is lower to 200~300centi-degree, and the lowest could be 160centidegree. This SCR technology has been successfully used in 2*800tpd lime kilns in Shandong Province. This is the first successive DeNOx project in China Lime Field.


Through interfacing the control system of SCR into lime kiln control system, the customer can coordinately control the whole plant system.

By modifying the design process and sCR DeNOx reactor, inventing new low temperature catalyst, it gave a significant result: NOx is less than 100mg/Nm3 (can be controlled under 50mg/Nm3), which is already achieving 2020 Natianal standard 150mg/Nm3 NOx emission.
