What are the monitoring methods and technologies of carbon emissions in key polluting industries?

A variety of carbon emission monitoring methods and technologies have been developed for key polluting industries. Key polluting industries refer to industries with high environmental pollution in industrial production, such as steel and petrochemical industry.

The emissions from these industries are not only harmful to the environment, but also affect people's health.

Therefore, in order to control the carbon emissions of these industries and protect the environment and people's health, countries have invested a lot of scientific and technological strength and funds to develop a variety of carbon emission monitoring methods and technologies.

At present, the commonly used carbon emission monitoring methods mainly include two advanced online monitoring methods and traditional offline monitoring methods.

On-line monitoring method mainly uses modern instruments to monitor the main pollutants such as oxygen, nitrogen and carbon dioxide in flue gas in real time, which has the advantages of real-time, accuracy and comprehensiveness. Off-line monitoring is the off-line analysis of pollutants in samples after sampling.

In addition, the development of carbon emission monitoring technology also includes wireless transmission technology represented by Bluetooth and other technologies, as well as the use of thermocouples, infrared spectroscopy and other technologies to achieve heat metering.

It should be pointed out that although the existing carbon emission monitoring methods and technologies are mature, there is still room for further improvement and innovation with the improvement of environmental protection requirements in the future.
