De-NOx (SCR) system Performance Test:
- Receiving the trust of AES-VCM Mong Duong Power Co., Ltd., we 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, flow, moisture content, gas composition (O2, CO2 and N2), SO2, SO3, NH3 concentrations; 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;
- Oxidation rate SO2 to SO3;
- Distribution diagram: flow velocity, temperature, NOx/O2 concentration, NH3 concentration;
- Comparing actual measurement results and DCS data;
- Data analysis, general evaluation and giving improvement plan.
