Selective Catalytic Reduction

The number of regions that regulate NH3 emissions, known as ammonia slip, are few, but the benefits of monitoring NH3 can be plentiful:

  • Cost savings of anhydrous ammonia
  • Decrease build up on air pre-heater
  • Lower contamination of waste solids.

To monitor NH3 slip, Thermo Fisher Scientific offers two main CEMS methods for process control and compliance applications:

  • Extractive dry basis with conversion at the stack
  • Dilution with NH3 conversion at the stack.
