Abstract: An adsorbent vessel comprising adsorbent material within the vessel interior positioned above at least one layer of support media, and a perforated baffle resting on the support media and not attached to the vessel shell whereby gas flow into the vessel from an inlet nozzle and a lengthwise oriented plenum is more evenly distributed for flow through the adsorbent material.

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.

Abstract: The present invention is a pressure adsorber vessel that employs a radial adsorbent bed with a variable perforated flow distributor to provide an effective uniform fluid flow though the adsorbent bed.
