Continuous Emission Monitoring Systems (CEMS)

 

Historically, Continuous Emission Monitoring Systems (CEMS) were used primarily to monitor flue gas components such as oxygen (O₂), carbon monoxide (CO), and carbon dioxide (CO₂) to support combustion control in industrial facilities. Today, CEMS play a critical role in ensuring compliance with stringent environmental regulations, including those set by the Iranian Department of Environment (IDOE), the European Environmental Agency (EEA), and other national and international authorities.

Industrial plants and facilities use CEMS to continuously collect, log, and report emission data to ensure that their operations remain within permissible limits. A standard CEMS setup typically includes:

a sampling probe, filters, sample lines, gas conditioning systems, calibration modules, and a set of gas analyzers designed to measure various environmental parameters.

 

Monitored Parameters

 

Key air pollutants and emissions typically measured by CEMS include:

 

  • Sulfur Dioxide (SO₂)
  • Nitrogen Oxides (NOₓ)
  • Carbon Monoxide (CO)
  • Carbon Dioxide (CO₂)
  • Hydrogen Chloride (HCl)
  • Particulate Matter (Dust)
  • Mercury (Hg)
  • Volatile Organic Compounds (VOCs)
  • Oxygen (O₂)

 

Additionally, CEMS can be equipped to measure:

 

  • Flue gas flow
  • Opacity (smoke density)
  • Moisture content

 

All gas components are reported in ppm or mg/m³, and particulate matter in mg/Nm³.

 

Advanced Monitoring Technologies

 

Delta Gas Mobin Group integrates cutting-edge technologies into its CEMS solutions to ensure high accuracy, reliability, and compliance:

 

  • NDIR (Non-Dispersive Infrared Analysis): for CO, CH₄, SO₂, and NOₓ
  • NDUV (Non-Dispersive Ultraviolet Analysis): for NO₂ and SO₂
  • Gas Chromatography (GC): for sulfur compounds and H₂S
  • Paramagnetic Analysis: for precise O₂ measurement
  • Chemiluminescence Detection: for NOₓ measurement

 

Technologies are selected based on the specific environmental requirements and technical demands of each project.
