Lafarge Mannersdorf installs a hot ESP and SCR

This plant installed a hot ESP to reduce the dust loading to a new SCR to 2 g/m3. This allowed selection of a relatively small amount of catalyst with narrow openings. This decision was made as an alternative of reheating gas and then locating the SCR at the tail end of the process. The unit has been installed since 2012 and is reported to be operating with some problems according to Bernhard Kopf of Lafarge. The problem is that the ESP is not meeting the predicted emission limits and is running much higher and therefore the catalyst requires periodic cleaning. However, deactivation has been negligible.
