New Regenerative Thermal Oxidation (RTO) with Integrated NOx Reduction

Odor emissions had been a problem for the cement plant in Wopfing, Austria for several years. Due to the location of the cement plant in a narrow valley, nearby villages were affected by its emissions. After 10 years of testing different waste gas cleaning systems, the Wopfinger Baustoffindustrie GmbH decided to install a Regenerative Thermal Oxidizer (RTO) to control odors, CO and organic components.

The desire of the authorities to reduce NOx emissions in the area led to the plant's decision to equip the RTO with an integrated Selective Non-Catalytic Reduction (SNCR) system. The installation has provided consistent high performance and reliability for more than 2 years.
