Removable cartridge for swing-type adsorption system
A removable cartridge for the adsorbent bed of a swing-type adsorber system defines a volume for retaining an adsorbent material within an adsorption bed housing during operation of the adsorption system. Additionally, the cartridge is configured to retain the adsorbent material therein so that the cartridge and the adsorbent material can be removed and installed as a unit.
1 . A pressure swing absorber unit comprising a housing defining an interior chamber, a removable cartridge assembly removably disposed in the interior chamber, the removable cartridge assembly comprising a wall assembly defining an absorber chamber, inlet and outlet screen members, and an absorber material disposed in the wall assembly, the inlet and outlet screen members being configured to retain the absorber material within the absorber chamber.
2 . The pressure swing absorber unit according to claim 1 , wherein the housing comprises a first cylinder, the wall assembly of the removable cartridge comprising a second cylinder disposed coaxially in the first cylinder.
3 . The pressure swing absorber unit according to claim 2 , wherein the first cylinder is configured to withstand a pressure of at least about 140 psig, the second cylinder being configured to withstand a pressure of no more than 100 psig.
4 . The pressure swing absorber unit according to claim 1 , wherein the removable cartridge assembly further includes hoist points at an upper end thereof.
5 . The pressure swing absorber unit according to claim 1 , wherein the absorber material comprises a plurality of beads.
6 . The pressure swing absorber unit according to claim 1 , wherein the removable cartridge assembly comprises a seal disposed on an outer surface thereof configured to form a seal between an outer surface of the removable cartridge and an inner surface of the housing.
7 . A removable adsorbent bed cartridge for a swing type adsorber system comprising a wall assembly defining an open inlet and an open the outlet, a plurality of adsorbent members disposed in the wall assembly, a first perforated member disposed at the inlet end and a second perforated member disposed at the outlet end, the first and second perforated members being configured to retain the adsorbent members therein, the wall assembly being configured to be received within a housing of an adsorber bed assembly of the swing type adsorber system.
8 . The cartridge according to claim 7 , wherein the cartridge is further configured to form a seal between an outer surface of the wall assembly and an inner surface of the housing, at a location between the inlet and outlet ends of the wall assembly.
9 . The cartridge according to claim 7 , wherein the seal is provided by an o-ring disposed on an outer surface of the wall assembly.
10 . The cartridge according to claim 9 , wherein the o-ring is configured to withstand a pressure differential generated by the head loss associated with the adsorbent material during operation of the swing type adsorber system.
11 . The cartridge according to claim 7 , wherein the wall assembly is cylindrical.
12 . The cartridge according to claim 7 additionally, comprising a flange extending from the first open end of the wall assembly and a plurality of apertures disposed in the flange.
13 . The cartridge according to claim 12 , wherein the apertures in the flange are configured to provide hoist points for the cartridge.
14 . The cartridge according to claim 7 , wherein the wall assembly is configured to withstand a pressure of no more than about 100 psig.
15 . The cartridge according to claim 7 , wherein the wall assembly further comprises an inner surface and a recessed area disposed on the inner surface adjacent the inlet end.
16 . The cartridge according to claim 15 , wherein the first perforated member includes an outer peripheral edge disposed in the recessed area.
17 . The cartridge according to claim 16 , wherein the peripheral edge defines a diameter that is greater than an inner diameter of a portion of the inner surface adjacent the recessed portion.
18 . The cartridge according to claim 17 , wherein a step is defined at the inner side of the recessed portion.
19 . A removable adsorbent bed cartridge for a swing type adsorber system comprising a wall assembly defining an open inlet and an open the outlet, a plurality of adsorbent members disposed in the wall assembly, a first perforated member disposed at the inlet end and a second perforated member disposed at the outlet end, the first and second perforated members being configured to retain the adsorbent members therein, and means for forming a seal between an outer surface of the wall assembly and an inner surface of a housing of an adsorber bed assembly of the swing type adsorber system.
20 . The cartridge according to claim 17 additionally comprising means for allowing the adsorbent material to be mechanically compressed after it is installed in the housing.
