CEMS for Iron and Steel Mills (Non-Ferrous Metals)

This continuous emission monitoring system (CEMS) for iron and steel mills and non-ferrous metal plants measures sulphur dioxide (SO2), nitrogen dioxide (NO2) and total particulate matter (PM) in stack and process exhaust gas. It combines extractive gas analysers, in-situ gas analysers and a particulate in-situ analyser, chosen for each source, from waste gas off a sintering belt to copper, zinc, lead and aluminium production. A data acquisition system (DAS) and data interface system (DIS) record the readings and pass them to the DOE / EPA server for compliance with the emission limit values.

Features

• Monitors SO2, NO2 and total PM / dust continuously
• Extractive and in-situ gas analysers, plus a particulate in-situ analyser
• Data acquisition system (DAS) and data interface system (DIS)
• Configured for sinter plants and for copper, zinc, lead and aluminium production

How it works

• SO2: NDIR, NDUV, GFC, FTIR, PAS or fluorescence (extractive); DOAS, GFC or FTIR (in-situ)
• NO2: NDUV, PAS or fluorescence (extractive); DOAS (in-situ)
• Total PM / dust: light scatter or beta absorption (extractive); transmissometry or triboelectric, double pass or single pass (in-situ)

Emission limit values

For production and processing of non-ferrous metals with a capacity of ≥ 0.5 tons per day for lead or cadmium, or ≥ 2 tons per day for other metals:

• Sinter plants (waste gas from the sintering belt): SO2 500 mg/m³, NO2 400 mg/m³, total PM 50 mg/m³
• Production of copper and zinc: total PM 20 mg/m³
• Production of lead: total PM 10 mg/m³
• Primary aluminium: total PM 10 mg/m³
• Secondary aluminium: total PM 10 mg/m³

DOE / EPA requirements

• Supplier listed as an appointed and approved company on the DOE / EPA website
• TUV / MCERT certificate
• Data acquisition system (DAS) and data interface system (DIS)

Applications

• Sinter plants
• Copper and zinc production
• Lead production
• Primary and secondary aluminium production
