Switzerland: Dürr is supplying a regenerative thermal oxidation system (RTO) to Jura Cement Fabriken integrated plant in Wildegg as the main stage in its air pollution control system. The upgrade is intended to enable the cement producer to comply with anticipated lower gas emission limits for carbon monoxide, hydrocarbons, and ammonia (NH₃). The supplier says its solution combines Dürr’s Ecopure RTO multiple-chamber principle with an optimisation of the existing process technology in the calciner. It is scheduled to start operation in 2022.

Jura Cement operates two integrated plants in Switzerland. It is part of the Switzerland-based Jura Materials Group, which has been part of the Ireland-based CRH since 2000.

US: Dragon Products has been fined US$67,000 by the Maine Department of Environmental Protection for exceeding air emissions regulations since 2013. Ammonia, carbon monoxide and particulate matter levels were all breeched, according to the Bangor Daily News newspaper. Other irregularities with standards were also noted, such as baghouse inlet temperature limits and clinker cooler opacity standards.
