Sulfur removal absorbents

Sulfur (hydrogen sulfide or organo-sulfur compounds) removal is critical to prevent risks to health and the environment, improve process safety and operation, and to meet product specifications. 

Hydrogen sulfide (H2S) is a very toxic and corrosive compound which needs to be removed from hydrocarbon and CO2 streams before they can be safely used by industry and homes. Upon the combustion of sulfur containing gas, sulfur dioxide can be formed which can lead to health (e.g. respiratory and cardiovascular disease) and environmental issues (e.g. acid rain). The corrosive nature of the H2S affects plant equipment and pipework, and along with organo-sulfurs species can cause downstream catalyst poisoning, costing industry billions of dollars per year in lost production.

Johnson Matthey is offering our market leading PURASPECTM  range of sulfur removal absorbents, in line with our vision for cleaner and healthier world. 

Our PURASPEC absorbents are proven over the last four decades to be a simple and effective solution to remove sulfur to very low concentrations within the gas processing, refining and petrochemical markets. These are also finding home in emerging sustainability and decarbonisation driven technologies such as plastics recycling, green hydrogen and carbon capture utilisation/storage.


Our latest patent protected innovation in sulfur removal technology, PURASPEC 1065, achieves the highest sulphur removal capacity in natural gas processing, boasting a 66% capacity increase to our most popular PURASPEC 1038A sulfur absorbent. The superior capacity of the latest generation sulphur removal absorbent translates into:

  • Most cost-effective solution in terms of cost per kilograms of sulphur removed
  • Lowest absorbent volume and vessel footprint
  • Longer absorbent life, giving the best lifecycle cost


Commercial and environmental pressures are setting increasingly tight limits on the levels of sulfur compounds allowed in gas and liquid streams for use and transportation. PURASPEC absorbents are designed to remove sulphur from natural gas, condensate/NGL, LNG, vent and shale gases and CO2 but the list is not exclusive.

The cornerstones of all PURASPEC sulfur removal absorbents are: 

  • Highest product capacities in the market 
  • Reliable performance and long predictable lives
  • Low and stable pressure drop due to inherent granule strength
  • Chemically bound sulphur species facilitating the spent absorbent disposal 
  • The absorbent does not contain associated hydrocarbons.


All our products are supported by dedicated regional teams and are fully re-processable at the end of life through our PURACARE service.
