Industrial Park VOCs Online Monitoring SystemBackground:

In chemical enterprises, VOCs are mostly emitted in an unorganized manner, and there are hundreds of thousands of potential leakage hazards in the industry. After classifying and analyzing the VOCs emissions of chemical enterprises, the Environmental Engineering Assessment Center of the Ministry of Environmental Protection has established the "Classification and Analysis of Eleven Major Pollution Sources" theory applicable to all chemical enterprises. Among them, combustion flue gas, process waste gas from production processes, and torch combustion flue gas under abnormal working conditions are organized emissions, while VOCs generated in the dynamic and static seals of equipment such as pumps, valves, flanges, open pipelines, storage and blending processes of raw materials, semi-finished products, and products, as well as product loading and unloading, wastewater storage, and treatment processes, are unorganized emissions.

Industrial Park VOCs Online Monitoring SystemIntroduction:

The online monitoring system for the environment of Lanju Park consists of three parts: front-end monitoring equipment (which can monitor VOCs, dust particles, carbon monoxide (CO), carbon dioxide (CO2), sulfur dioxide (SO2), nitrogen dioxide (NO2), nitric oxide (NO), ozone (O3), methane, hydrogen sulfide, noise, temperature and humidity, etc.), data transmission network, and management platform. It can implement monitoring and surveillance of industrial parks for ordinary office, electronic, mechanical, chemical and other industries.

This system has the characteristics of fast deployment, convenience and flexibility, real-time monitoring and real-time release of monitoring data, with over limit warning function, and can be viewed and remotely monitored on both mobile and computer ends in real time. Provide data support for environmental decision-making such as prediction, warning, traceability, and governance.

Monitoring standards:

Strictly implement current national and industry standards. The main current standards that should be followed are as follows. At the time of publication of this technical specification, all versions shown are valid. All standards will be revised, and both the supply and demand sides should explore the possibility of using the following new versions of the standards. When there is a contradiction, the higher standard of current technical requirements shall be followed.
