Abstract
The present invention generally relates to the attenuation of vacuum blower noise using a silencer. More particularly, the present invention relates to a low-cost, reliable and efficient silencer for reducing noise levels in adsorption-based gas separation plants from the discharge of the vacuum blower or from the feed blower inlet, to about the 90 dBA level or less, at the silencer opening to the atmosphere. The silencer includes at least one reactive chamber(s) to attenuate low frequency pulsations and at least one absorptive chamber(s) to attenuate noise at medium to high frequency noise.
