Catalyst Cleaning, Rejuvenation and Regeneration

Don’t Replace... Clean and Regenerate!

Typically, less than half the activity is used before SCR catalyst is considered “spent.” SCR-Tech offers proprietary and patented processes based on proven technologies that extend the useful life of SCR catalyst and substantially improve its NO_x removal efficiency for significantly less cost than purchasing new. Our processes are capable of not only physically cleaning and rejuvenating the most severely plugged, blinded or poisoned catalyst, but of also chemically reactivating deactivated catalyst.

The economic advantages are unequivocal:

• significantly less cost than purchasing new catalyst
• No disposal cost for spent catalyst as hazardous waste

SCR-Tech is the clear choice:

• Innovative, patented and proprietary technologies
• Proven processes
• Independently-verified results
• All catalyst types and OEMs
• Large stock of regenerated catalyst on-hand

Cleaning, Rejuvenation and Regeneration

SCR-Tech offers two distinct services that can extend and/or restore NO_x reduction performance:

• Cleaning & Rejuvenation: Using DI-water based cleaning and ultrasonic rejuvenation methods, SCR-Tech can remove large particle ash (LPA) and fly ash from severely plugged catalyst without damage, and without loss of remaining activity. Rejuvenation can significantly extend NO_x reduction performance for severely plugged, partially deactivated catalyst. Rejuvenation cannot, however, be used to restore activity to catalyst that has been fully deactivated due to chemical poisoning. [more…]
• Regeneration (ReGen™): For poisoned and / or deactivated catalyst, our proprietary, patented and fully-guaranteed ReGen process addresses all deactivation causes and fully restores catalytic activity, often to levels beyond original. In addition to fully restoring catalytic activity and NO_x reduction performance, this process removes catalyst poisons such as arsenic, as well as specific compounds known to promote the oxidation of SO₂ to SO₃ within the catalyst.

SCR-Tech services all catalyst types and OEMs: SCR-Tech has experience servicing all types of commercially available honeycomb, corrugated and plate-type catalyst including Argillon/Siemens, BASF, BHK, CERAM, Cormetech, Englehard, Haldor Topsøe, Hitachi, Kawasaki, KWH..

SCR-Tech R&D continues to develop and enhance its cleaning, rejuvenating and regenerating processes for specialty catalysts.

Achieve Maximum NO_X Reduction Potential

At SCR-Tech, our goal is to reinstate the maximum achievable NO_x reduction potential in the most economical manner, without changing the physical, chemical and/or mechanical properties of your catalyst. The most efficient and cost-effective means of restoring catalyst activity level is determined and a custom catalyst exchange program is designed. We have successfully restored catalyst activity for power plants burning coal, natural gas, refinery residues, pet coke, municipal solid waste, sewage sludge and biomass.
