SCR Performance Test:
- Receiving the trust of AES Mong Duong Power Co., Ltd, Chugai Technos conducted performance test for SCR system 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.
- Scope of Work: Emission gas monitoring, pressure differential measurement and ammonia consumption survey.
- 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, NH3 concentration;
- Comparing actual measurement results and DCS data;
- Data analysis, general evaluation and giving improvement plan.
