NANOCHEM® GuardBed™ Purifiers Remove Sulfur from Fuels, Gases, and Other Refinery Products
NANOCHEM® GuardBed Series purifiers can be used for desulfurization 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-0.1 ppm 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.
Examples of NANOCHEM® GuardBed Performance
For a more complete review of technical performance, please review the Application Segment Literature pertinent to your interests (see below). Immediately below are two examples of GuardBed performance for natural gas and for diesel fuel.
Remove Sulfur from Natural Gas
Natural Gas: Dimethyl Sulfide Removal: NANOCHEM® GuardBed has the highest capacity of all competitor materials tested for removal of sulfur components from natural gas.
Conditions:
Temperature: 68°F; Pressure: 3 psig; Challenge: 12.3 ppm dimethyl sulfide (DMS) 9.0 ppmv; tert-butyl mercaptan & 9.0 ppmv tetrahydrothiophene in natural gas; GHSV: 60,000 h-1
Remove Sulfur from Diesel (ULSD)
Ultra Low Sulfur Diesel Fuel (ULSD) – Removal Efficiency for Sulfur Species: NANOCHEM® GuardBed reduces sulfur content of ULSD to less than 1 ppmw and shows significantly better performance at higher temperatures versus other materials.
Why NANOCHEM® GuardBed is Better
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.
