De-NOx System (SCR) Performance Test:
- Receiving the trust of Hung Nghiep Formosa Co., Ltd, we conducted performance testing for De-NOx system (SCR) of all 3 units.
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 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;
- Oxidation rate SO2 to SO3;
- Distribution diagram: flow velocity, temperature, NOx/O2 , NH3 concentration;
- Comparing actual measurement results and DCS data;
- Data analysis, general evaluation and giving improvement plan;
