nh3 control of emissions Safe and efficient

The efficiency of systems with CO 2 depends more on the application and the climate than with other refrigerants. For all refrigerants, there is a decline in system efficiency with increasing condensing temperatures, and CO 2 is among the refrigerants with the steepest drop. The good thermo-physical properties of CO 2 can compensate to some extent, but there is a limit.

  • Emissions Archives - NH3 Fuel Association

    NH3 is a carbon-free fuel, so it has the potential to reduce CO2 emission from the power plant when used as a fuel. However, NH3 has combustion characteristics different from conventional hydrocarbon fuels. The N atom in the ammonia molecule causes high NOx emission through combustion reactions.

  • Reducing NH3 Slip in Selective Catalytic Reduction (SCR

    SCR (Selective Catalytic Reduction) is a method to reduce NOx emissions by converting the NOx to Nitrogen (N 2) and water (H 2 0) by the reaction of NOx and Ammonia (NH 3 ). This reaction is sometimes referred to as De-NOx. The reaction between NOx and NH 3 is never perfect, although it can achieve efficiency rates often higher than 95%.
