De-NOx (SCR) system performance testing:
- Receiving the trust of AES-VCM Mong Duong Power Co., Ltd., we conducted performance testing for De-NOx system (SCR) of unit 2.
Using simple equipment system, easy to disassemble, meet the pipes both horizontal and vertical, difficult to operate, tight space. Sampling and monitoring devices comply with Japanese JIS standards.
Monitoring parameters: Temperature, flow, moisture content, gas composition (O2, CO2 and N2), SO2, SO3, NH3 concentrations; continuously monitoring NOx/O2 by gas portable analyzer.
- Content reports:
- Basic parameter emission.
- NOx/O2 concentration, De-NOx Efficiency.
- Ammonia slip.
- Relationship between NOx and NH3 concentration.
- Oxidation rate SO2 to SO3.
- Distribution scheme: flow rate, temperature, NOx/O2 concentration, NH3
- Compare actual measurement results and factory monitoring data.
- Analyze data, general evaluation and give improvement plan.
