Selective Catalytic Reduction (SCR) is a way of converting Nitrogen Oxides (NOx) with the aid of a catalyst into nitrogen (N2) and water (H2O) at a lower temperature level.
The reductant, typically aqueous ammonia or urea solution is added, injected to the exhaust gas stream for the selective catalytic reduction.
Catalytic oxidation activity (CO/VOC) is achieved by additional impregnation with noble metals.
GEA was the first company to use and continuously improve selective catalytic reduction (SCR) in the glass industry, in the cement industry and now also in metallurgical industry.
With the operating data, the performance measurements carried out and the activity studies of the catalysts used, GEA is constantly adding to its experience for process optimization and for the benefit of users in all industrial sectors.

选择性催化还原 (SCR) 是一种转换氧化氮的方式,该物质也称为 NOx。在燃烧煤炭、石油产品、天然气以及生活垃圾和工业生产的有害垃圾时,会产生污染,释放出废气。即便优化了燃烧,也会有大量 NOx(主要污染物之一)产生。氧化氮和空气中其他成分反应,生成臭氧,从而导致所谓的热雾。
