When one is looking to attain noise reduction by the means of a silencer, BCS offers a wide range of vent silencers for pressurized gas for various applications related to acoustic insulation, soundproofing ie., protection of workers against noise, preservation of acoustic environment, limitation of noise emissions in the energy sector. The blowdown of natural gas systems must typically be done quickly in a very short time span during maintenance operations on pipelines. This often produces noise readings well above tolerable levels. Natural gas silencers control blowdown noise through a reactive-absorptive process, which provides good attenuation across all octave frequency bands. The selection and design of natural gas silencers is dependent on the following application specific factors.
