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

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

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. 

Below are some of the questions discussed during the webinar:

  • Does Wahlco provide the complete U2A system turnkey, from the urea dissolver to the Ammonia Flow Control Unit (AFCU) probes?

  • When is there more financial benefit to move from ADD to U2A as a possible solution?

  • What is the energy consumption associated with converting urea to ammonia? Where does the heat come from?

  • Are there regulations on the ammonia produced before it is injected into the SCR?

  • Does the AOD system control the ammonia injection into the SCR?

  • Do you have any AOD systems installed on simple cycle rapid start (0-10 full load) gas turbines?

  • What is the requirement of urea and water for a typical subcritical 600 MW unit boiler to reduce NOx gases from 500 to 200 ppm?

  • What quality of water must be used in the process if mixing with dry urea?

  • Does this system apply to supercritical boilers for maintaining water chemistry by injecting ammonia? Since the final product is a solution of ammonia and carbon dioxide, and CO2 needs to be eliminated before injecting into the boiler, would it be a good source of ammonia for dosing rather than transporting it from the manufacturer?

  • Is there any possibility of solid particles from urea passing through the system to the SCR catalyst?

  • What is the cost of installation for an 800 MW supercritical unit using this process?

  • What system is recommended for a demand range of 25-200 Pph?
