Product Information

Introduction of SCR De-NOx

PaNox™ is the trade mark for De-NOx SCR system developed by PANASIA. Ltd. The trade mark represents the pride of PANASIA. which possesses the highest level of capabilities for De-NOx SCR system.

1.1 Influence of NOx

NO + NO2 = NOx

  • Problems with Climate and Air Quality
    - Greenhouse Effect
    - Ozone depletion
    - Smog
    - Acidification (Acid rain)

  • Influence on humans
    - NO2 may decrease the long function and increase the risk of respiratory functions such as acute bronchitis, cough and phlegm, particularly in children.

  • Influence on the environment
    - NOx contributes to acidification, smog and ground level ozone.

1.2 Selective Catalytic Reduction (SCR)

1.3 Functional Principle of the Catalyst

  1. External diffusion of NH3 to Catalyst surface
  2. Internal diffusion of NH3 into the catalyst pore
  3. NH3 adsorption on the active centers
  4. NO diffusion from gas phase to adsorbed NH3
  5. Reaction of NO and NH3 to N2 and H2O
  6. Desorption from N2 and H2O form catalyst surface
  7. Diffusion of N2 and H2O into the gas Phase

1.4 The Reduction Agent for SCR De-NOx System

Ammonia (NH3)

Regular reduction agent Need more safety equipment Simple dosing system

Urea (NH)2CO

The most popular Reduction Agent More safe than ammonia dosing system Added heat duty for decomposition (300~350°C)

1.5 The Urea property as Reduction Agent

Two concentrations are widely available

  • Industry 40% w/w
  • Transportation 32.5% w/w
