Sonata Vent Silencers are used to attenuate noise produced by the expansion of Gas & Steam from elevated pressures to atmospheric pressure. Vent Silencers are effective in reducing high frequency noise produced at start up or when venting to atmosphere. High priority in design is placed on the inlet diffuser for backpressure and distribution of flow.
Sonata Vent and Blowdown Silencers are used throughout the world to control the noise associated with venting pressurized gases to atmosphere. Sound Control offers a wide range of standard and custom designs that are used in vent and blowdown applications for natural gas, steam, air or virtually any other pressurized gas. Design features of vent and blowdown silencers may include single or multiple inlets, multi-stage diffusers, and acoustically lined shells or absorptive splitter panels packed with mineral wool or fibreglass packing. Typical materials of construction are carbon and stainless steel but materials of higher alloy makeup can be used to provide longer service for applications with high temperature or corrosive environments.
The most important design aspect of the Sonata Vent Silencer is the inlet diffuser. The diffuser is effective in distributing the flow evenly through all of the splitter panels in the silencer. This 1st stage process also provides sound reduction. It can also be designed to restrict back pressure upon any valve that may be upstream of the silencer. Flow through absorptive splitter panels (2nd stage) then takes some of the energy out of the gas stream, thus providing additional reduction. Typically, these silencers are excellent for control of high frequency noise levels.
