Process Gas Silencers

Additional Details

Silencers for nitrogen, oxygen, carbon-di-oxide, hydrogen-rich gasses and other process gasses can be supplied for both online stress silencer as well as vent silencers. The prime requirement for a vent silencer is its capacity to handle with total honesty the rapid release of large quantities of steam from high pressure to atmosphere and attenuating elevated levels of noise generated at the vent for steam at a wide range of load and temperature conditions. The silencers are made out of concentric annular acoustic cylinders included with a robust steel casing with the dished end or flat end at one end.

The fluid enters through the diffuser and passes through the annular space within the acoustic packing where the sound energy is absorbed. The straight flow path into the annular acoustic cylinders ensures minimum pressure drop. A cold cowl for rain protection is available as an optional item.

The material of construction offered shall be suitable for the method gas application.
