The Nanochem GuardBed Series of Deep De-Sulfurization purifiers specifically targets sulfur removal - to (and beyond) sub PPM levels for many liquids and gases such as natural gas, refinery feed streams, and fuels (gasoline, diesel, jet).

GuardBed? Purifiers Remove Sulfur from Fuels, Gases, and Other Refinery Products

Nanochem? GuardBed? Series purifiers can be used for de-sulfurization of:

  • Natural gas
  • Liquid hydrocarbons (natural gas liquids, iC4 / iC5 feedstock)
  • Fuels (diesel, jet fuel, logistic fuel, bioethanol)
  • LPG
  • Olefins
  • Refinery off-gases
  • Biogas
  • Propane
  • Heavy fractions

Typically, sub-ppm performance is achieved; and in many applications, sub-0.1ppm sulfur can be expected routinely.

Compare Nanochem? GuardBed?performance with that of conventional desulfurization materials which is typically limited to H2S removal down to approximately 1-5 ppm.

Nanochem? GuardBed? Outperforms Conventional Polishing and Sulfur Removal Solutions

Conventional materials also suffer from common processing problems brought about by the presence of moisture, heavy hydrocarbons, aromatics, carbon dioxide, and unconventional sulfur species.

Additional complications with conventional materials include low purification capacity, and difficulties with handling, regeneration or disposal.

Nanochem? GuardBed? Series purifiers represent a scalable solution. Configurations are available for the laboratory, pilot plant, or for full-scale production.

Nanochem? GuardBed? is a series of purification solutions designed to be “super-polishers” in desulfurization applications ... at a cost that is competitive relative to conventional, lower performance polishing desulfurization solutions.
