Industry Installations include corn dryers, fryer lines, PVC ovens, wood industry dryers, pulp and paper recovery boilers, refinery waste fuel boilers, foundry cupola, glycol incinerator, and mixed fuel co-generation.
Proven Reliable Technology
The Wet Electrostatic Precipitator (Wet ESP) is used on industrial exhaust that operate at or near the dew point and contain condensable oils, tars and stickly particulate matter that are typically sub-micron in size. By nature these aerosol emissions are difficult to wet in a scrubber and require tremendous amount of energy (pressure drop) to remove from the exhaust. The Wet ESP provides substantial improvements in collection efficiency and in power consumption for these applications.

Operation
The same charging and collecting principles as noted before for the Dry ESP also apply to the Wet ESP. Pre-treatment evaporative cooling allows vapor phase aerosols to cool and condense so they can be charged and collected. Collection tubes are used in place of collection plates and the collected precipitate is typically hydraulically rinsed or flushed off of the collection tubes. The Wet ESP is easily combined with pre and post treatment scrubbers for the control of acid gases.
