The airborne noise is produced when venting of Air, Nitrogen, Oxygen, Blast gas and Carbon-Di oxide to the atmosphere. The gas vent silencer is similar construction of vent silencer. The natural gas vent silencer offered in circular type. The gas enters through the silencer inlet (reactive section) where the pressure is reduced as per the requirements and process condition and it is passes through the annular space between the acoustic packing where the sound energy is absorbed.
These are used to attenuate the high as well as low frequency noise to the desired noise level.
