Ohio Lumex and W.S. Hinton & Assoc. offer a joint service to help utilities manage and optimize SCR performance by using in-situ measurements to perform a direct and comprehensive assessment and characterization of the SCR. The initial benchmarking is incorporated into the latest modeling techniques to provide the tools necessary to effectively and holistically operate and manage the SCR. Additional benefits include the ability to predict the impacts of fuel and operational factors on deNOx and mercury oxidation as well as the effects of ammonia slip, HBr, and SO3 on downstream equipment.

Benefits:

  1. Independent providers of technical expertise, testing, modeling, and consulting
  2. Joint effort between industry leaders in respective fields
  3. Fast, complete, direct assessment of SCR performance
  4. Use of state of the art non-extractive measurement techniques

Direct In-Situ Measurements (inlet, outlet, interlayer)

Use state of the art instrumentation and proprietary techniques to measure:

  • NH3
  • ​​​Mercury Oxidation
  • SO3
  • NO3
  • As
  • Se
  • Hydrogen Halides (HCl, HBr, etc.)

SCR Management

  • Latest modeling techniques
  • OEM, advanced, and regenerated catalysts
  • Predictions of fuel and operational impacts of deNOx and Mercury Oxidation
  • Effects of ammonia slip and SO3 on downstream equipment

The process starts with the collection of available plant data and discussion to identify unique concerns and goals. This is followed by an initial direct field assessment (benchmark) that is then incorporated into the long-term SCR management program. Additional periodic field performance testing is recommended to fine tune the program and provide ongoing insight into the actual performance of the SCR. This holistic approach is completely independent of other equipment or service providers, ensuring that the utility receives the most cost-effective and technically optimal options available.

  1. Benchmarking
  2. DeNOx Performance
  3. SO2 Conversion Performance
  4. Mercury Oxidation Performance
  5. Catalyst Management
  6. SCR Management
  7. Long-Term Performance Confirmations
