Regenerative Thermal Oxidation (RTO) with integrated NOx reduction

1 Introduction

Odor emissions had been a problem for the cement plant in Wopfing located in Piestingtal in Lower Austria close to Wiener Neustadt, Austria for several years, due to its location in a narrow valley. Here, Wopfinger Bau-stoffindustrie GmbH (formerly Wopfinger Stein- und Kalkwerke) has been producing lime since 1911. The company has been owned by the Schmid family since 1940. In 1970 the company started to produce binders and plasters in addition to lime. Cement production was added in 1980 (Figure 1). Internationally recognized inventions like the Parallel Flow Regenerative Lime...
