Lesser noxious emissions with SCR technology [Oct 2011]

As NOx emissions are produced by all combustion processes, Dürr EES offers the selective catalytic reduction (SCR) technology for more than just its own air pollution control systems
Environmental technologies are the basis for ecological and economic pollution control in many different industrial sectors. As environmental protection is getting more and more important the emission values will be tightened. Dürr Environmental and Energy Systems (EES) has responded to this: the specialist for environmental equipment now offers selective catalytic systems for the reduction of NOx.
For Dürr EES these new emission limits are relevant mainly for the design of Ecopure VAR thermal oxidizers. Especially for high combustion temperatures of over 1,100° C in the combustion chamber (thermal NOx), and if nitrogen is contained in the fuel (fuel NOx), selective catalytic reduction (SCR) is the only efficient method. In both cases NOx concentrations are high after the combustion process, and these can be reduced with SCR.
