AxTrap Granular, High-Capacity Media

AXTRAP is superior to the leading granular iron-oxide coated media in the following ways:

  1. Lower pressure drop.
  2. Less dust unloading the spent media because our media has less fines.
  3. Easier cleanouts due to minimal agglomeration and hardening.
  4. AXTRAP can be safely vacuum removed without need for water and fear of heating of the spent media, normally straight into vacuum boxes.
  5. Injection of air might be considered to improve run times by as much as 50% longer. The addition of air will NOT make AXTRAP rock hard when spent like the other leading iron-oxide coated granular media.

Product Description O2 Loading Capacity Pressure Drop Spec Sheet
AxTrap-4001/4002 Granular
High-capacity H2 removal up to 10,000 ppm.
Highly porous iron-oxide coated g6ranular media. Formulated to meet stringent LFG and digester gas treatment requirements. Media can be used in systems designed for beneficial end-use such as CHP, fuel for boilers, etc. AxTrap media doesn’t cake together like some other granular media and combined with the SulfAxTM System contributes to even greater ease of removal and no need for foam filters. Works well without O2, however performance is optimized with some oxygen. Up to 14% wt anaerobic, and 28% wt partially aerobic in Lead/Lag design, otherwise 9-14% in single vessel. Low Pressure Drop Range .1 to 1 psi AxTrap 4001 Data Sheet Adobe_PDF_file_icon_24x24

AxTrap-4003 Granular
Resists NMVOCs that may be present in LFG and may interfere with removal efficiency of 4001/4002.
Built to resist higher levels of non-methane VOCs in landfill gas that can sometimes interfere with reactions with H2S. Does a better job on light mercaptans, if needed. Not for use in California. Works well without O2, however, performance is optimized with some oxygen.
Up to 14% wt anaerobic, and 21% wt partially aerobic in Lead/Lag design, otherwise 9-14% in single vessel. Range 0.1 up to 2 psi depending on design. AxTrap 4003 Data Sheet Adobe_PDF_file_icon_24x24
AxTrap-4101/4102 Granular
High daily rates of H2S in anaerobic conditions.
AT 4101/4102 are useful where we have high amounts of H2S to remove per day (normally more than 100 lbs. per day and in anaerobic gas) and need a higher capacity product. Not necessary. Up to 20% by weight capacity in anaerobic conditions. Up to 20% wt in anaerobic conditions for Lead/Lag design. 0.1 up to 2 psi depending on design. AxTrap 4101 Data Sheet Adobe_PDF_file_icon_24x24
AxTrap 4102 Data Sheet Adobe_PDF_file_icon_24x24
AxTrap-4011 Granular
High daily rates of H2S in anaerobic conditions.
Deeper removal of organic sulfurs, in this case vent from asphalt plant. AT 4011 is used outside of California and AT 4012 is used in California. Best for aerobic application such as asphalt vent applications. 8-12% wt for lower oxygen levels and up to 17% wt for streams with greater than 5:1 ratio of O2:H2S 0.1 up to 2 psi depending on design.td> AxTrap 4011 Data Sheet Adobe_PDF_file_icon_24x24
