Filtration and Separation
Ceramic candle filter
Hot gas filtration with ceramic candles for the removal of particulate matter and acid gases.
GEA high-temperature filters with ceramic elements remove particulate matter and acidic gases. The ceramic filter elements show very low dust emissions (< 2 mg/Nm3) and are thermally stable under high operating temperatures. No cooling of flue gases are required and no thermal heat energy is wasted when implementing them.
Filter elements are cleaned online during operation through separate, compressed air jet pulses. The filter elements are placed in a single or multi-compartment housing to handle flow rates of large volume. This construction technique allows for maintenance of a single module while others continue to operate without interruption of the process altogether.
The injection of lime-based reagents allows for control of inorganic gaseous emissions like HF, HCl, and SOx. The rigid candle structure enables surface filtration and forms a first layer of reactive dust for absorption processes.
When required, the candles can be enriched with a catalyst (BisCat) providing effective NOx removal by using an upfront ammonia injection and replacing a conventional selective catalyst reactor (SCR).
