Eliminate Ammonia Handling Hazard for SCRs Through On-Site Urea Conversion Technologies

Wahlco, Bill Hankins, Webinar, Webcast Experts, Eliminate Ammonia Handling, SCRs


With today’s global regulatory environment placing more stringent limitations on NOx emissions for both utility and industrial boilers, (pending NOx limits in the range of 30 – 200 mg/Nm3), SCR will continue to remain the dominant NOx control technology. Ammonia is used as a reducing agent within the SCR in quantities often exceeding 1000 lb/hr for large installations.  Moreover, a great number of lower ammonia demand SCR systems (<100 lb/hr) (<30 lb/hr) are being installed in smaller industrial applications such as cement and food processing plants and institutional applications such as hotel laundries, hospitals and universities.  In all cases, ammonia must be injected upstream of the SCR catalyst and this often requires the transport, on-site handling, and storage of either anhydrous or aqueous ammonia with the associated risks of ammonia spills and liability costs for both permitting and operation.  These risks can be eliminated using an on-site urea to ammonia conversion processes since urea is non-toxic, non-flammable, and is not subject to regulations governing toxic or hazardous materials.

Don't Bring In Ammonia for Your SCR - Convert Urea On-site and On-Demand

Two proprietary and patented urea conversion processes are available from Wahlco, Inc. to provide ammonia on-site and “on-demand”.  Urea-To-Ammonia (U2A®) systems are designed for large ammonia demand SCR installations.  Newly-developed Ammonia-On-Demand (AOD®) systems are specifically tailored to meet the ammonia demands for smaller SCR systems. AOD® systems were specifically developed to address the ammonia requirements for a large and growing number of industrial, commercial, and institutional boilers located in “NOx Non-Attainment areas” which are and/or will be subject to Federal and State Implementation Plans to reduce NOx emissions. 

This informative webinar, presented by Bill Hankins - VP Sales U2A® for Wahlco, Inc., will address the specific ammonia delivery challenges facing both large and small scale boiler owners and operators where SCR is, or is expected to be, installed.  Specific topics will include:

  • Urea infrastructure and conversion/hydrolysis chemistry
  • How U2A® and AOD® process equipment and controls are integrated into urea conversion systems
  • U2A® versatility for coal, oil, and gas fired plants
  • AOD® system applied to stationary gas-diesel-and fuel oil -fired turbines widely used for power production
