Packed Bed Scrubber
Turner EnviroLogic Packed Bed Scrubbers are used to remove odors and fumes. They are also well suited to neutralize chlorinated and fluorinated gases such as Hydrochloric acid and Hydrogen Fluoride. Packed bed scrubbers are often used as a secondary system in conjunction with thermal oxidizers to remove acid gases that may form in the combustion process.
Contaminated gas travels upward through a column of packing material. The packing provides a large wetted surface area to induce contact between the gas and the scrubbing liquid. The scrubbing liquid is distributed over the packing material with nozzles and flows downward through the packing. Chemicals are added to the packed bed scrubber with an adjustable metering pump. These chemicals neutralize the odors and/or acid gases. Scrubbing liquid conductivity and/or pH are monitored to determine the amount of chemicals that need to be added to the scrubber.
