  • Patent number: 8545604
    Abstract: A modular and compact adsorbent bed structure is disclosed for use in an adsorption-based gas separation plant. The conventional adsorbent bed in a gas separation plant is replaced with a plurality of modular adsorbent bed units connected to make the adsorbent bed structure. The modular design requires lower fabrication and maintenance costs; is easier to transport; and is easier to load with adsorbent material.

  • Patent number: 8268043
    Abstract: A modular and compact adsorbent bed structure is disclosed for use in an adsorption-based gas separation plant. The conventional adsorbent bed in a gas separation plant is replaced with a plurality of modular adsorbent bed units connected to make the adsorbent bed structure. Modular adsorbent bed units of this invention provide higher capacity of product per unit volume of adsorbent material (i.e., increased adsorbent utilization) as compared to that obtained from conventional adsorbent beds. The modular design requires lower fabrication costs; is easier to transport; has less maintenance and repair requirements; and is easier to load with adsorbent material.

  • Patent number: 7819223
    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.

  • Patent number: 7766996
    Abstract: The present invention relates to a method of reducing or elimination pressure pulsations and noise created by blowers in a gas separation plant. The method employs two identical and 180° out of phase blowers synchronized together to provide both a large flow of air and active noise cancellation to eliminate pressure pulsations. The two blowers are synchronized in such a way that pressure pulses created by one blower will actively be cancelled by the pulses generated by the other blower. At the same time, both blowers will work together to force a large quantity of gas flow in or out of the plant. The twin set of blowers can be used for feed or vacuum applications in the plant. This way large tonnage plant capital costs can be reduced by eliminating the need for an expensive silencer and a single large custom-made blower.
