De-NOx System (SCR) performance testing:
- 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 pipes both horizontal and vertical, difficult to operate, tight space. Sampling and monitoring equipment comply with Japanese JIS standards.
- Monitoring parameters: Temperature, flow, moisture content, gas composition (O2, CO2 and N2), SO2, SO3, NH3 concentrations; monitoring continuously NOx/O2 by gas portable analyzer.
- Content reports:
- Basic parameter exhaust gas.
- NOx/O2 concentration, De-NOx efficiency.
- Ammonia slip.
- Relationship between NOx and NH3 concentration.
- Oxidation rate SO2 to SO3.
- Distribution diagram: flow rate, temperature, NOx/O2 , NH3 concentration.
- Compare actual measurement results and factory monitoring data.
- Analyzing data, general evaluation and giving improvement plan.
