Mong Duong 2 Thermal Power Plant

De-NO(SCR) system Performance Test:

  • Receiving the trust of AES Mong Duong Power Co., Ltd, Chugai Technos conducted performance test for De-NOx system (SCR) of unit 2.
  • Using simple equipment system, easy to disassemble, meet the ducts both horizontal and vertical, difficult to operation, tight space. Sampling and monitoring equipment comply with JIS standards.

  • Monitoring parameters: Temperature, pressure, velocity, flow rate, moisture content, gas composition (O2, CO2 and N2), SO2, SO3, NH3 concentration; continuous monitoring NOx/O2 by gas analyzer.

  • Report content:
    • The basic exhaust gas parameters;
    • NOx/O2 concentration;
    • NOx removal efficiency;
    • Ammonia slip;
    • NH3/NOx molar ratio;
    • Conversion rate of SO2 to SO3;
    • Distribution diagram: flow velocity, temperature, NOx/O2 concentration, NHconcentration;
    • Comparing actual measurement results and DCS data;
    • Data analysis, general evaluation and giving improvement plan.
