Gas Scrubbers and Knock Outs (KO) remove traces of liquid droplets from gas streams to protect downstream equipment from damage and failure. They are typically used upstream of gas treating equipment that contains dry desiccants or mechanical equipment such as compressors. They are also used downstream of equipment where liquids have condensed from the gas.
The Gas Scrubber is designed to handle light liquid loads and does not take the place of a primary separator. Unlike a coalescing element, scrubbers and KOs work on the basis of gravity separation with a high efficiency mesh pad or vane pack.
Apergy has been designing and fabricating scrubbers and KO's for over four decades. Our scrubbers and KO's provide confidence and reliability that our customers rely on.
