[Project Case]Monitoring of unorganized emissions in coking enterprises to promote green development in the industry

​ Project Background

Air pollution from coking enterprises is a complex and important issue that has a significant impact on the environment and human health. The air pollutants produced by coking enterprises mainly include particulate matter (such as PM2.5, PM10), sulfur dioxide (SO2), nitrogen oxides (NOx), volatile organic compounds (VOCs), etc. Among them, the emission of VOCs ranks second among various industrial industries, and the exhaust gas contains toxic and harmful substances such as benzene , which is extremely harmful to human health. In order to improve air quality, various companies have stepped up efforts to prevent and control air pollution. By establishing a complete monitoring system, air pollution problems can be discovered and solved in a timely manner, ensuring environmental quality.

According to the current national air pollution prevention and control policies and environmental governance requirements, combined with the severity and urgency of Shanxi’s current ecological and environmental protection work, local enterprises and relevant departments need to further reduce particulate matter, nitrogen oxides, sulfur dioxide and other waste gas emissions by strengthening monitoring Phenomenon. Zwinsoft assisted a coking company in Shanxi to establish a more complete monitoring system to monitor exhaust gas emissions in real time, providing a basis for the company to optimize production processes and improve equipment.
