For mercury removal from gas streams, APC offers two mercury control systems: MercPure Fixed Bed (FB) Series systems and MercPure powdered activated carbon (PAC) Series systems.
MercPure FB Series Systems
APC's MercPure Fixed Bed (FB Series) systems provide the highest removal efficiencies for mercury using fixed adsorption beds of specialty, granular activated carbon media that are custom-selected for the application. APC's activated carbon media for these systems are available to address both low- and high-temperature exhaust gas streams. APC is media-independent and will select the best media available on the market for the application. APC offers multiple options to protect the carbon bed from particulate fouling, including baghouses and the unique Ultra High-Efficiency Filter (UHF®) unit, which can precede the adsorption vessel(s) to remove ultra-fine condensed and solid particulate down to and below 0.01 micron in size, greatly extending carbon media life, and allowing continuous mercury control at high efficiency.
MercPure PAC Series Systems
APC's MercPure powdered activated carbon (PAC Series) injection systems include carbon metering and injection systems, interconnecting ductwork and piping, and downstream fabric filter (if not already in place) to deliver mid to high removal efficiencies (up to 95% typ.). These mercury control systems also work in both low and high-temperature conditions and are ideal for larger gas volumetric flow rates where fixed adsorption beds become infeasible.
Applications for MercPure Series mercury control systems include: hospital waste incinerators, municipal waste incinerators, waste-to-energy plants, wastewater treatment plants (sludge incinerators), fossil fuel fired boilers, retort furnaces, fluorescent bulb manufacturing, chlor-alkali plants, taconite plants, chemical plants, and specialty refineries.
