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.

Ultrasonic-Regeneration means: most thorough chemical deep-cleaning under mild conditions complete removal of all catalyst poisons ultrasonic cleaning of the fine microporous structure of the catalyst no damage or change of the microstructure

From deactivated to as-good-as-new condition: Reduction of SO2/SO3 conversion rate de-activation like new material multiple regenerations possible mechanical quality unchanged life of the catalyst is already redoubled after the first regeneration

In order to offer our customers the high savings potential by ultrasonic regeneration of DeNOx – catalysts, we keep our approved and highly developed regeneration method ready for them. In addition, we offer services that mean complete order processing from a single source.

Moreover, in Europe we can always offer transportation of the catalysts from the client to our plant and back after regeneration. Since the founding of our company, we have been working with a partner who has extensive experience in dealing with the often sensitive goods. Transportation is always undertaken by using air-suspended vehicles and skilled personnel. We also have experience with sea transports. For example, the logistical processing for the regeneration of catalysts from the Finnish Meri-Pori (200 m³) did not cause any problems and was carried out on schedule during a three-week shutdown.
