Reduce NOx in the cement plant
In an increasing number of countries, NOx emissions limits regulated by law are set to become even stricter. Cement plants that fail to comply with these regulations risk being switched off. With its CemCat SCR solution, thyssenkrupp already offers the technology needed to significantly reduce NOx emissions down to 100 mg/Nm³. Additionally, CemCat SCR technology can lead to an 60% reduction in propane and ethane emissions. The solution improves air quality through the after-treatment of exhaust gas and various process optimization measures. This allows cement plant owners to comply with strict regional regulations and take a huge leap forward in protecting the environment from acid rain and the other negative effects of NOx emissions.
Cut the excess with CemCat SCR
thyssenkrupp offers flexible CemCat SCR systems that can be adapted to any process condition in new or existing cement plants. For installation in an existing plant, the system is ideally integrated, which saves space and causes minimal interference in kiln operation.
The CemCat SCR system not only eliminates emissions but, thanks to its high-dust setup, it ensures the reliability and high performance of the catalyst. Dust cleaning is essential in high-dust SCR plants to ensure that the nitrogen oxides are converted in the catalyst with maximum efficiency. Blockages in the honeycomb channels result in a greater drop in pressure, higher energy consumption, and increased wear of the catalyst elements. Catalyst dust cleaning is performed using dust blowers that have been optimized to meet the rigorous demands of the cement process in terms of reliability and energy consumption.
The SCR design guarantees that the catalyst is used to its full potential. It ensures optimal gas distribution to maximize the efficiency of the catalytic converter.
While the reactor house is heated to operating temperature, the SCR housing expands significantly. This is accounted for with a sophisticated, decoupled suspension system between the steel construction and the SCR housing.
