Cartridge | <strong>Filtration</strong>Figure 4: Cross section of the wall of a Cerafil TopKat element showing the nano catalyst embedded into the wall of the element.lutants across a number of industries,including: glass, carbon black manufacture,cement kilns, and coal production.A number of established and emerg ingtechnologies have been developed to meetregulated emission limits. These include:barrier filters, dry, semi-dry and wetscrubbing, cyclones, elec trostatic precipitators,and catalyst-conversion processes.These clean-up processes are used, oftenin combina tion, to achieve at least the regulatedemission limits. Process choice isaf fected by many factors, apart from theregulations in force, not least of which areeconomics and reliability.However in order to meet tighterlegislation and permit limits these technologiesneed to be used sequentiallyand sometimes in various steps of theprocess flow diagram to bring the emissionsbelow the newly mandated EPArequirements.In recent years, Clear Edge has advancedthe technology to develop CerafilTopKat, a pioneeringbreakthrough technology combiningthe advantages of Cerafil with an incorporatedactive catalyst for the removalof Nox, Dioxin, Sox, Rox and VOCs.This patent pending technology protectsthe catalyst from poisoning by incorporatingit in the wall of the filterelement (a common problem with SelectiveCatalytic Reduction (SCR) technology)see Figure 4.Clear Edge has been researching anddeveloping the Cerafil TopKat technologyplatform for over 10 years and hasbuilt up many years of experience applyingthis newly emerging technologyin critical applications. A typical plantlayout is shown in Figure 5. Clear Edgehas thousands of filter elements inmany applications worldwide coveringa variety of industrial uses.The main features and benefits ofCerafil TopKat include:• Can replace and consolidateinefficiend Electrostatic Precipitator(ESP), SCR and conversion processesFigure 5: Typical plant layout incorporating Cerafil TopKat and typical performance data.20 • August 2013 • www.filtnews.com
