FILTRATH® – DeDust : Control of Dust/Particulate Matter (PM)
Built into an emission control system and used in conjunction with a reverse pulse air cleaning system, FILTRATH® filter elements are highly-effective in controlling emissions of PM (< 2mg/Nm3) for hot gas temperatures applications in the range 250-1,000°C (i.e. well above the maximum operating range for fabric filter media and well below the achievable emissions levels for non-barrier filters).
FILTRATH® – DeSOx, DeDust: Control of Acid Gases (SO2, HCl, HF) & PM
Used in conjunction with dry sorbent injection (DRI) (e.g. sodium bicarbonate, hydrated lime) FILTRATH® elements from RATH enable highly-effective (>98%) control of acid gas components (e.g. SO2, HCL, HF) as well as PM. Alternatively, used with upstream injection of powdered activated carbon (PAC), FILTRATH® CF elements are also highly-effective in controlling emissions of mercury.
FILTRATH®CAT – DeNOx, DeDust : Control Oxides of Nitrogen (NO, NO2) & PM
Performance can be further enhanced with the introduction of a SCR-coated filter element, FILTRATH®CAT. When used in conjunction with upstream injection of an ammonia-based reductant (e.g. aqueous ammonia, urea) FILTRATH® CAT enables highly-effective (>95%) control of NOx emissions as well as PM for temperatures up to 420°C. Operating above the DeNovo synthesis temperature also means FILTRATH®CAT elements are highly-effective in the control of emissions of dioxins and furans (PCDD/F)
