Automatic Waste Gas Monitoring System

What is an automatic emission monitoring system?

Effective solution for the control of environmental pollution
In the context of climate change and environmental pollution becoming more and more serious, the strict control and monitoring of emissions is extremely necessary. The automatic emission monitoring system was born as an effective technical solution, helping the authorities to monitor emissions continuously, accurately and timely.

Harmful effects of industrial emissions

Emissions refers to gases emitted from industrial production, transportation or other human activities. Emissions mainly include pollutants such as carbon monoxide (CO), sulfur dioxide (SO2), nitrogen oxides (NOx), hydrocarbons (HC), volatile organic vapors (VOCs)… If not handled and controlled properly, these gases will directly release into the environment, causing adverse effects such as:
  • Increasing the greenhouse effect, the earth’s temperature rises leading to climate change.
  • Air pollution, affecting human health. The pollutants in exhaust gases are the cause of respiratory diseases, cancer.
  • Causing acid rain, degrading soils and ecosystems.
  • Depleting the ozone layer protects the earth.
Therefore, the control and treatment of emissions is extremely urgent, helping to minimize their adverse impacts on the environment. Countries around the world have set strict standards and regulations to control emissions. Vietnam has also issued emission standards for industries such as: QCVN 19: 2009 / BTNMT, QCVN 20: 2009 / BTNMT, QCVN 21: 2009 / BTNMT…

The benefits of automatic emissions monitoring systems

To be able to monitor and control emissions effectively, there is a need for automatic, continuous and reliable monitoring systems. Continuous Emission Monitoring System (CEMS) was born for that purpose.
CEMS is a system that allows continuous measurement and monitoring of pollution parameters in exhaust gases such as CO, SO2, NOx, dust (TSP, PM10, PM2.5), VOC… The data of the system is transmitted to the control and storage center, helping the authorities to monitor the emissions of factories and industrial parks and take timely measures when they exceed the threshold.
Advantages of automatic exhaust gas monitoring system:
  • Enables 24 / 7 continuous, uninterrupted emission monitoring.
  • Provide data directly, not depending on people.
  • High precision and reliability. The advanced sensors have very high precision.
  • The ability to detect early emissions.
  • Save manpower and periodic inspection cost compared with manual system.
  • Automatic warning function can be integrated when the threshold is exceeded.
  • Data can be transmitted to the authorities for timely processing.

The components of an automated emissions monitoring system

A complete automated emissions monitoring system typically includes the following items:
  • Measuring equipment: Including sensors, gas analyzers to measure pollution parameters. Can be electrochemical sensors measuring CO, SO2, NOx or gas analysis equipment such as FTIR, GC-MS…for qualitative and quantitative analysis of organic compounds.
  • Sampling system: Including air duct, sampling head, sample pump… to get exhaust gases into the analytical equipment.
  • Data processing and transmission systems: These include signal processing devices, which convert signals from sensors into digital data and transmit to the control system and SCADA.
  • Monitoring and warning software: SCADA software collects and processes data, displayed in the form of tables and graphs. There are automatic alerts when the threshold is exceeded.
  • Other accessories: Electrical cabinet, control computer, data transmission modem, electrical system…

Some questions about automated emission monitoring systems:

Question: What is an automatic emission monitoring system?
A: Automatic exhaust monitoring system (CEMS) is a system that allows continuous measurement and monitoring of pollution parameters in exhaust gases such as CO, SO2, NOx, dust, VOC…
Question: Why is it necessary to install an automatic emission monitoring system?
A: This system helps in 24 / 7 continuous emission monitoring, providing accurate and timely data so that the authorities have effective pollution treatment measures. It replaces manual periodic sampling.
Question: What are the main components of an automated emissions monitoring system?
A: The main components include measuring equipment, sampling system, data processing and transmission system, monitoring and alerting software.
Question: What emission parameters are usually monitored?
Answer: Common parameters such as CO, SO2, NOx, dust (TSP, PM10, PM2.5), VOC, NH3… depending on the source of emissions to be monitored.
Question: What equipment is used for exhaust gas analysis?
A: Electrochemical sensors measure CO, SO2, NOx. Gas analysis devices such as GC-MS, FTIR for the analysis of organic compounds.
Question: How is the data of the system stored?
Answer: The data is transmitted back to the SCADA system, which can then be stored in the database and retrieved through the software.
Question: How does the system need to be maintained?
A: It is necessary to periodically maintain the measuring equipment, check the sensor calibration. Update the software and maintain the computer system periodically.
