Not to know the chemical industry VOCs governance new technology

The strengthening of the policy level has made the prevention and control of VOCs pollution one of the key tasks of the environmental protection work of many enterprises, among which the management of VOCs in the chemical industry is the top priority. Fortunately, new technologies developed in recent years have provided a great boost to VOCs governance in the chemical industry. These new technologies include leak detection and treatment (LDAR) technology, plasma technology, biotechnology, photocatalysis, gaseous molecular fission and other technologies.
Volatile organic compounds (VOCs) are important precursors to the formation of ozone and PM2.5 fine particulate matter pollution. China's VOCs emissions are still growing, and data show that China's VOCs emissions exceed 20 million tons/year.
In order to improve air quality, China is accelerating the promotion of VOCs pollution prevention and control, in the "13th Five-Year" volatile organic matter pollution prevention and control work plan "clearly proposed that by 2020, the establishment and improvement of VOCs pollution prevention and control management system, the implementation of key areas, key industries VOCs pollution reduction, total emissions down by more than 10%. In addition, many governments have also introduced VOCs emission reduction work plans for the region and different industries, and 21 provinces and autonomous regions have begun to levy pollution fees on VOCs.
The strengthening of the policy level will make VOCs pollution prevention and control become one of the key tasks of the environmental protection work of many enterprises, and this will also drive the explosive growth of the VOCs governance, monitoring, third-party services and other markets, and the relevant data predicts that during the "13th Five-Year Plan" period, the market size of VOCs prevention and control will reach 140 billion yuan.
Petroleum refining and petrochemical, coal chemical, chemical storage and transportation are the key industries for VOCs emissions, and relevant data show that VOCs emissions in the petrochemical industry alone have reached 3 million tons/year. VOCs emissions from the petrochemical industry can be classified as organized and unorganized emission forms, including a total of 12 emission source items.
VOCs are diverse, from a wide range of sources, and with complex components, a single enterprise may face problems such as insufficient enthusiasm, insufficient funds and resources for the prevention and control of VOCs. According to relevant surveys and studies, the emissions of chemical enterprises (organic chemicals, fine chemicals and other enterprises) in the emission sources of VOCs rank first in the national industrial VOCs emission sources.
There are two main forms of VOCs production in chemical enterprises:
The pollutants in the discharged gas are related to the chemical production process and working conditions, and there are many types and large differences in nature. The emissions are organized and the emissions can be estimated.
The second is volatilization through other links, the VOCs produced because of its strong diffusion and reactivity, can be transformed under relative conditions through a variety of complex chemical reactions, the emissions of VOCs produced in this form can not be accurately estimated, and the analysis of the source is also difficult.
