Our flagship organic catalyst has the highest activity of our HPC catalyst lineup with > 15% mass transfer improvements over DEA-catalyzed HPC systems. In addition to being more active, it has significantly lower vapor losses, high resistance to degradation (especially in the presence of oxygen) and is only needed in minor proportions.

CATACARB organic catalysts are easily adopted through regular solution makeup, and monitoring of chemistry is simple with our included analytical procedure recommendations. Organic catalysts are best suited for the following applications:

  • Ammonia synthesis gas
  • Hydrogen gas
  • Natural gas for pipeline (NG) or liquified natural gas (LNG)
  • Substitute natural gas (SNG)
  • Iron ore reduction gas
  • Methanol synthesis gas

For treatment of gases with exceptionally high oxygen contents, or when a volatile catalyst is not permittable, our inorganic catalyst can be adopted. The inorganic catalyst enhances both absorption and stripping efficiencies by more than 40% above those of comparable HPC processes. The inorganic catalyst is a high activity, stable promoter compatible with oxygen that doesn’t contaminate the treated gas or recovered CO2 streams. In fact, the HPC solution catalyzed by our inorganic catalyst is so stable that multiple plants have been running the same solution for 20 years with < 10% solution makeup. Furthermore, it offers effective corrosion inhibition, protection against wet CO2 attack, and protection against erosion/corrosion and stress corrosion cracking.

The inorganic catalyst is best suited for the following applications:

  • Ethylene oxide (EO) recycle gas
  • Flue gas
  • VAM recycle gas
  • Nitrous oxide product stream
  • Autoclave recycle oxygen stream
