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.

The filter elements are chemically inert and corrosion resistant. Gas cleaning in one step. A multifunctional filter for the sim...
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。
健康快乐的奶牛是成功和可持续牛奶生产的关键。因此,保持奶牛健康是每个奶农努力的核心。奶牛的健康受到许多因素影响,例如根据奶牛个体需求进行适当喂养、良好的饲养条件以及新鲜的空气、水和光照。而且,挤奶方式对奶牛的健康状况也有很大的影响。GEA 因其“优质挤奶理念”而闻名,不断致力于进一步发展,并在动物健康和牛奶质量方面取得更好的成果。
各行各业都在努力实现净零排放目标,同时遵守严格的脱碳法规和立法。与此同时,公司必须平衡日益增长的质量、产品开发和工艺优化需求,此外,还必须努力提高盈利能力。应对这一挑战需要采取 GEA 提供的协作和整体方法。
咖啡、可可、牛奶、肉类、鱼类和蛋类 - 这些日常主食在很大程度上依赖集约农业。随着新食品技术的兴起,我们有了更多可持续的替代品。我们采访了 GEA 液体、发酵和灌装部门的高级副总裁 Reimar Gutte 博士,探讨其中的可能性和政策。
