NOx Reduction (SCR/SNCR) for Industrial Emissions

Yara 300 HuH

In 2014, Yara acquired German maker H+H Umwelt- und Industrietechnik to offer SCR technologies for reducing NOx (Nitrogen Oxides) emissions in maritime and land-based, industrial applications.

NoxCare® is a complete portfolio of technology, reagents, after-treatment processes and services for nitrogen oxide emissions abatement.

Nitrogen oxide emissions (NOx emissions) can be reduced most effectively with after-treatment techniques such asSelective Catalytic Reduction (SCR) and Selective Non-Catalytic Reduction (SNCR). Both are proven NOx reduction technologies able to remove up to 98% percent of the harmful NOx emissions from exhaust or flue gas (in the case of SCR) . Whether you have to start treating your NOx emissions or you have been doing it for several years already, NOxCare offers a complete package of solutions , from setting up an SCR or SNCR system to dosing reagents on a daily basis. 

Our NO x Care offering also includes serviceswith assistance in product storage, technical testing and telemetry, safety training and analysis . 

As the world leader in nitrogen chemistry, Yara is uniquely positioned to provide a reliable supply of NOx reduction reagents such as anhydrous ammonia, ammonia solution and urea solution. Yara can deliver the reagent of your choice from our extensive network of plants offering continuous sourcing back-up. Our product knowledge in urea and ammonia helps Yara bring the reagent into your processes in a safe and reliable manner. 

Yara has been developing its nitrogen oxide air pollution reduction technology capacity. Through recent acquisitions and strategic investments, Yara is now a leading provider of the two main NOx after-treatment technologies SCR and SNCR.

SCR – Yara Environmental Technologies is a leading provider of high-performance SCR systems for the removal of up to 98% of NOx emissions. More than 1300 Yara SCR systems are installed in cogeneration plants, industrial boilers and ships worldwide. Yara SCR systems were formerly marketed by H+H Umwelt-und-Industrietechnik GmbH and Strabag Energy Technologies GmbH (now known as Yara Environmental Technologies). Yara Environmental Technologies in Austria is the centre of competence for basic / detail engineering and turnkey solutions of SCR & SNCR DeNOx systems.

With over 560 systems installed globally our flue gas cleaning systems are used for the efficient removal of pollutants from flue gas using catalytic & non-catalytic denitrification processes. Hazardous substances (NOx, SO2, SOx, Hg, Dioxin, etc.) are substantially reduced through an ideal combination of our systems to provide tried-and-tested, leading-edge technologies for environment-friendly power plants and industrial applications.

Our clients are:
