Natural Gas Vent Silencer

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. This noise is the product of two phenomena:

Shock noise - the instantaneous loss of pressure across a choked flow device
Turbulent mixing - the ripping of the air as the vent gas decelerates to zero velocity during discharge to atmosphere

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.

Noise attenuation requirements
Evaluation of natural gas flow
Blowdown time limits
Most cost effective approach to meet needs
Durability and performance for the given application environment

The specialists at dB Noise Reduction will develop the natural gas silencers to meet the needs and specifications of your application.
