DeNOx SCR

.Besides primary measures, Selective Catalytic Reduction (SCR) is the most effective method for controlling nitrogen oxide emissions (NOx) from combustion sources. It is a commercially proven flue gas treatment technology that has been demonstrated to remove over 98 percent of the NOx contained in combustion system exhaust gas. The catalyst is at the heart of the SCR process. It creates a surface for reacting the NOx and ammonia, and allows for the reaction to occur within typical flue gas temperature ranges.
Hamon uses a similar technology to reduce also VOC or CO content.

Thorough knowledge in the design of all types of heat recovery systems including heat exchangers made of glass or fluoroplastic tubes to de-saturate the flue gas downstream a wet scrubbing system allows for minimum energy consumption when the flue gas needs to be heated.

  • The catalyst replacement management plan can easily be  optimized by our in-house capacity to execute Computerized Fluid Dynamics (CFD) studies which improve the distribution of the flue gas mixed with ammonia over the catalyst surface and by the possibility of installing an additional catalyst layer in the future.
  • The CFD also allows for a reduced pressure drop through the whole system.
  • When required, the cleaning system, with compressed air or steam sootblowers, is specifically designed so that it has no impact on the integrity of the catalyst modules.
  • Amongst the possible options, the catalyst can be sized for an additional treatment of Dioxins and a separate layer of catalyst can be added in the reactor for CO reduction.
