Mercury removal absorbents

Mercury removal from hydrocarbon streams is a stringent requirement in order to avoid corrosion of equipment, poisoning of catalysts and to comply with environmental regulations.

The high toxicity of mercury and its ability to accumulate in the food chain can pose very significant and long-term damage to human health and the environment. Process equipment corrosion due to liquid metal embrittlement or alloying may cause catastrophic plant loss of containment.

Johnson Matthey is offering our market leading PURASPECTM range of mercury removal absorbents, inline with our vision for a cleaner, healthier world.

Our PURASPEC range of absorbents are tailored for effective and complete mercury removal in gas and liquid phase duties. PURASPEC mercury absorbent portfolio combines decades of industry experience with the newest innovations in manufacturing technology.

PURASPEC fixed bed absorbents are suited for a range of applications within the gas processing, refining and petrochemical markets. These are also suitable for use in emerging sustainability and decarbonisation driven technologies such as plastics recycling, green hydrogen and carbon capture utilisation/ storage.

Johnson Matthey is proud to present our latest innovations in mercury removal, combining enhanced protection against mercury contamination with more efficient use of its active components. As a result, the next generation of PURASPEC absorbents have significantly improved mercury removal capacity, faster kinetics and higher resistance to process upsets.

These impressive benefits give our customers operational flexibility, better management of their capital and operational expenditure and less hazardous absorbent waste:


Best mercury removal performance (PURASPEC 1198/1199/5198/5199):
  • Lowest absorbent volume for a given duty, reducing the CAPEX for new projects
  • Longer absorbent lives, giving the best lifecycle cost
  • Short-fill options for existing facilities, reducing OPEX

Most robust in difficult duties (PURASPEC 1193/1194/5193/5194):
  • High capacity, reliable performance and long predictable life in "fit-and-forget" system
  • Robust formulations that withstand plant upsets such as the carryover of free liquids
  • Products maintain physical integrity for unloading at the end of life


PURASPEC
absorbents are designed to remove wide range of elemental mercury concentrations from natural gas, condensate/NGL, LNG, vent and shale gases and CO2 but the list is not exclusive. PURASPEC mercury removal absorbents operate flexibly within any flowsheet (e.g. upstream/downstream of driers, acid gas removal units etc). Thus, Johnson Matthey’s PURASPEC absorbent bed provides protection for much of the plant and avoids the problems and costs associated with widespread plant contamination and mercury emissions that have been encountered by many operators.

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

Johnson Matthey representatives should be consulted to determine which product is most appropriate for any given application/duty. Send us a message to request a quote or ask our advice. We’d be happy to hear from you.
