Applications for MercPure Series mercury control systems include sewage sludge incinerators (SSI’s) at wastewater treatment plants, gold processing plants, hospital waste incinerators, municipal waste incinerators, waste-to-energy plants, fossil fuel fired boilers, LNG production plants, antimony processing plants, retort furnaces, fluorescent bulb manufacturing, chlor-alkali plants, taconite plants, chemical plants, and specialty refineries.
For mercury removal from gas streams, APC offers two types of mercury control systems:
APC’s MercPure Fixed Bed (FB Series) systems provide the highest removal efficiencies for mercury emissions – at some sites in excess of 99.99% removal – using fixed adsorption beds of specialty activated carbon media, custom-selected for the application. APC is media-independent and selects the best media available on the market for the application, considering a proven track record, cost, and longevity.
Our proven approach to equipment and system design prevents any downtime or operational issues associated with the carbon beds, offering multiple options to protect the carbon bed from particulate fouling where particulate matter is present. This includes baghouses (for dry particulate matter), the unique Ultra High-Efficiency Filter (UHF®) unit (for condensed or wet, multi-phase particulate), or fixed filters that precede the adsorption vessel. It allows for the removal of fine condensed and solid particulate down to 0.01 micron in size, greatly extending carbon media life and allowing continuous mercury control at high efficiency. Mercury emission removal efficiencies by APC MercPure FB systems are commonly 99%+ as measured by owner compliance testing, with carbon beds lasting several years or more.
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 the low 90s%). These mercury control systems also work in both low and high-temperature conditions and are ideal for very high gas volumetric flow rates where fixed adsorption beds are infeasible.
