In-situ-cleaning

of DeNOx catalysts

There is a typical case of application for successfully cleaning DeNOx -catalysts in the DeNOx-plant which does not require any complex dismantling and reassembling: The removal of ammonium salt from the surface of DeNOx-catalysts in incineration plants.

Here, we have several years of experience in restoring activity from 90 up to 100 %.

Besides the cost saving, this procedure has enormous logistical advantages as shorter shutdowns can also be used.

Comprising a catalyst volume of up to 50 cubic metres simply requires three to five days which includes the building site installation.

During the “Wildeshauser Catalyst Days” in September 2008, incineration plant owners reported their experiences with our in-situ-cleaning, in detail.
