In most cases, chemicals stored in polyethylene tanks require venting. In some instances, the harmful fumes emitted from the chemicals can not be directly released to the atmosphere. In order to reduce the harmful fumes before they evacuate the system and to control air pollution, fume scrubbers are installed.
Fume scrubbers are installed to remove or neutralize the harmful substances emitted from combustion, or in this case, the storage of chemicals. These scrubbers function by introducing an acid gas sorbent material into the gas stream and a particulate matter control device.
