Scrubbers

Wheelabrator's answer to sulphur dioxide (SO2) and acid gas emissions is the variety of scrubbing systems we offer for removing SO2 and acid gases from utility and industrial coal-fired boilers, waste-to-energy systems, and other industrial processes.

Wet FGD Systems

Wet scrubbers are used where SO2 and acid gas control requirements are most stringent. Wheelabrator technology includes open spray (single and double loop) tower and Dual-Flow Tray designs. We are also experienced in the use of sodium- and calcium-based absorbents and special customer waste streams.

Spray Dryer Systems

Spray dryer scrubbers are used for applications with less demanding SO2 and acid gas control requirements. A lime- or sodium-based scrubbing liquor is atormized into the flue gas to absorb the acid gases. Simultaneously, the hot flue gas evaporates the scrubber liquor, leaving a dry product for disposal. The reaction products and process ash are then collected by an electrostatic precipitator or fabric filter system.

Dry Injection Systems

In combination with fabric filters, dry injection systems offer an economical, reliable choice for applications requiring lower levels of SO2 and acid gas emission control. They are often superior to other designs in terms of cost efficiency, thanks to their simplicity and lower capital and maintenance costs.
