- HIGH-EFFICENCY GAS-PHASE ADSORBER CELLS
This Recommended Practice (RP) covers the design and testing ofmodular gas-phase adsorber cells in single pass or recirculatingair-cleaning systems where the need for high-efficiency removal ofgaseous contaminants is a requirement. Three types of modular cellsare discussed in detail.
Adsorber cells described in this RP have been classified intofour types, namely:
a) Type I (serpentine-bed) cell (application specific)
b) Type II (flat-bed or tray-type) cell
c) Type III (not discussed in detail)
d) Type IV (vee-bed) cell
The four types of adsorber cells, though differing in theirrespective configurations, have common features and components.
Test requirements of this RP cover the cell as filled withgranular activated carbon. Typically, the carbon used in adsorbercells manufactured in accordance with this RP is sized to 8 Ã— 16 USmesh. Performance of the cell for a specific contaminant is afunction of the adsorbent used and the operating conditions. Theseconditions should be specified in addition to the requirementsoutlined in this RP.
This RP is limited to gas-phase adsorbers used for nuclear,military, and heavy industrial applications. These adsorber cellsrequire prior qualification of the cell design and carbon fillingmethod. The manufacturer should perform production airflowresistance and leak testing.
NOTE: Products and procedures discussed in thisRP may involve hazardous materials, operations, and equipment. ThisRP does not purport to address all of the safety problemsassociated with the use of the RP. It is the sole responsibility ofthe user to consult and establish appropriate safety and healthpractices and to determine the applicability of regulatorylimitations prior to use of this RP.
