Abstract:
A method to increase the pressure of a feed gas, comprising:providing a first set of conditions within a first chamber; introducing a first quantity of feed gas into said first chamber, said first chamber containing a first adsorbent material capable of adsorbing at least a portion of said first quantity of feed gas under said first set of conditions and desorbing at least a portion of said first quantity of feed gas under a second set of conditions; allowing at least a portion of said first quantity of feed gas to adsorb onto said first adsorbent material; providing a second set of conditions within said first chamber; whereby at least a portion of said first quantity of feed gas is desorbed from said first adsorbent material; releasing said first quantity of feed gas at an increased pressure from said first chamber; providing a third set of conditions within a second chamber, substantially by the time said first quantity of feed gas is released from said first chamber; introducing a second quantity of feed gas into said second chamber, said second chamber containing a second absorbent material capable of adsorbing at least a portion of said second quantity of feed gas under said third set of conditions and desorbing at least a portion of said second quantity of feed gas under a fourth set of conditions; allowing at least a portion of said second quantity of feed gas to adsorb onto said second adsorbent material; providing said fourth set of conditions within said second chamber; whereby at least a portion of said second quantity of feed gas is desorbed from said second adsorbent material; and releasing said second quantity of feed gas at an increased pressure from said second chamber.
