WebSilent Nox is a selective catalytic reduction system for diesel and natural gas engines from 400kW to 10MW employed in mission critical installations. A compact solution to control NOx, CO, VOCs, HCs, PM, and NH3 slip all in one engineered system. CCC is a SCR System designer and manufacturer. WebA selective catalytic reduction (SCR) system may be provided in the exhaust gas stream for removing nitrogen oxides (NOx). An SCR system may comprise a reductant injector located upstream of a catalyst and the reductant injector may inject a liquid reductant into the exhaust gases before they contact the catalyst. Suitable liquid reductants may ...

Selective Catalytic Reduction (SCR) - Wartsila.com
WebSelective catalytic reduction considerations. There are some factors that must be considered before installing an SCR system. Firstly, the SCR systems function best at higher temperatures - 400°F and above. Keeping this in mind, the specific catalyst manufacturer will determine the desired range. Secondly, watertube boilers are better suited ... Selective catalytic reduction (SCR) is a means of converting nitrogen oxides, also referred to as NO x with the aid of a catalyst into diatomic nitrogen (N 2), and water (H 2O). A reductant, typically anhydrous ammonia (NH 3), aqueous ammonia (NH 4OH), or a urea (CO(NH 2) 2) solution, is added to a stream of flue … See more The NO x reduction reaction takes place as the gases pass through the catalyst chamber. Before entering the catalyst chamber ammonia, or other reductant (such as urea), is injected and mixed with the gases. The … See more SCR catalysts are made from various porous ceramic materials used as a support, such as titanium oxide, and active catalytic components are usually either oxides of base metals (such as vanadium, molybdenum and tungsten), zeolites, or various See more Most catalysts are given a finite service life due to known amounts of contaminants in the untreated gas. The most notable complication is the formation of ammonium sulfate See more History SCR was applied to trucks by Nissan Diesel Corporation, and the first practical product "Nissan Diesel Quon" was introduced in 2004 in Japan. See more Several nitrogen-bearing reductants are currently used in SCR applications including anhydrous ammonia, aqueous ammonia or dissolved urea. All those three reductants are widely available in large quantities. Anhydrous ammonia … See more In power stations, the same basic technology is employed for removal of NO x from the flue gas of boilers used in power generation and industry. In general, the SCR unit is located … See more • Acid rain • Catalytic converter, which also catalyzes NOx conversion but does not use urea or ammonia See more WebTechnical paper on selective catalytic reduction of NOx using ammonia or urea, including process principles, chemical reactions, and the types of SCR catalysts [DieselNet … draughn aviation llc
