Nowata Charcoal / Carbon Canisters

7NC20 & 11NC22 Canisters
(click photo for larger view)

   The Nowata replacement canister type cartridges are the most convenient type of activated carbon adsorbers for systems with flow rates up to 57 GPM (using multiple canisters). The canisters make charcoal replacement much easier and cleaner than loose charcoal beds. Canisters keep the operator from handling the messy charcoal. The contaminated spent charcoal is difficult to dispose of unless it is contained in a canister form. Each canister contains approximately 31 Ibs. of granulated activated carbon. In a typical 400 gallon glycol dehydration system, a single canister will usually last between 8 to 10 weeks depending upon the amount of hydrocarbon contained in the natural gas stream.
     


See the Charcoal Housings page here.

OPERATION:

The Nowata 11NC22 replacement canister is designed for liquid flow from outside through the granulated charcoal into the center core. The treated fluid then exits out the sealed end of the center core. The hydrocarbon contaminants are removed through the adsorption process rather than mechanical filtration as in particulate filters. The low velocity or flow rate through the charcoal bed maximizes the removal efficiency. The Nowata charcoal canister is rated for a maximum of 1.33 GPM flow rate per canister. Lower flow rates per canister will allow for high operating efficiencies and longer canister life. The removal efficiency is also a function of the fluid operating temperature which should be held below 300°F. Operation at a temperature greater than 300°F is not recommended. A single canister will usually last between 8 to 10 weeks in a 400 gallon glycol system.
 

11NC22 CANISTER FEATURES:

  • 11" OD x 20" long,  or,  11" OD x 22" long charcoal canister.
  • Carbon steel perforated metal shell and core.
  • Buna rubber end seals bonded to shell.
  • 11NC22 canister holds approximately 31 lbs. of activated carbon.
  • Fits all Nowata  "C" Series  filter vessels and many competitors' housings.
  • Canisters keep the operator from handling the messy bulk charcoal.
     (We do not sell bulk charcoal)
     

    Maximum flow rate per canister is approximately 1.33 GPM.
    Multiple canister vessels can provide flow rates of up to 57 GPM.

    Typical uses of activated carbon for oil and gas operations include:

    • Amine and Glycol purification

    • Hydrocarbon adsorbtion

    • Wastewater treatment

    • Boiler feed water treatment
