Progress in SCR DENOX and Silencing Technology for Diesel Engine Exhaust Systems

This paper will comprise descriptions of Topsoe's and Silentor's combined SCR/Silencing systems, including among other issues detailed acoustic calculations, based on impedance and small-channel analyses, of a total exhaust system with the combined SCR/silencing, sound measurements on an already installed system, presentation of advanced flow distribution calculations in combined SCR/silencing systems and efficiency measurements on the newest SCR installations.
