Focus on VOCs Control
China Local Practices and Successful Examples Under the Key Role of Activated Carbon
VOCs Volatile Organic Compounds Treatment Technologies-Activated Carbon
Volatile organic compounds (VOCs) treatment is related to the quality of the atmospheric environment and people’s health. Across the country, all regions have taken active actions and carried out a series of fruitful practices. Many successful cases have emerged, providing valuable experience for other regions.
What is the best way for VOCs treatment?
Activated carbon adsorption is an important technical means for VOCs control, and its adsorption effect is closely related to the quality of activated carbon.
Activated carbon relies on porous structure to adsorb VOCs, but the adsorption capacity of different types of VOCs is different, and the adsorption effect is affected by factors such as concentration, temperature, and humidity. When the concentration is high, the adsorption amount increases, and the adsorption effect decreases when the temperature and humidity increase.
This article introduces several successful VOC control examples with activated carbon.
VOC Control Examples-Shanghai: How do you treat VOC exposure?
In Shanghai, VOCs abatement technologies are applied to deal with the complex pollution problems represented by ozone and fine particulate matter.
VOCs surveys have been carried out since 2007, and industrial source emission reduction has been promoted in stages.
In the 1.0 stage, more than 2,000 enterprises completed emission reductions by focusing on key industries; in the 2.0 stage, the scope was expanded and a new route was adopted to promote precise governance of nearly 2,400 enterprises.
In terms of social source pollution control, relevant transformations of gas stations, oil storage depots and tank trucks were completed.
Some companies use activated carbon adsorption technology in the process of VOCs control, and strictly select products with iodine value, specific surface area and strength that meet the standards in accordance with the quality requirements of activated carbon.
By establishing and improving the regulatory standard system, implementing the “one factory, one policy” system, focusing on problems and providing precise assistance, and strengthening monitoring and supervision, Shanghai’s air pollution control has achieved remarkable results. The excellent rate of the ambient air quality index (AQI) in 2022 has increased significantly compared with 2013.
VOC Control Examples-Lianyungang: What is the best treatment for VOC?
The VOCs comprehensive treatment demonstration benchmark project created by Lianyungang Xuwei New District has achieved remarkable results.
After the project is completed and put into use in August 2022, the total amount of VOCs will be reduced by 59.87t/a, and the annual emission reduction rate will reach 29%.
When activated carbon adsorption technology is applied in some links of this project, the quality of activated carbon is strictly screened to ensure that its iodine value, specific surface area and strength meet the requirements.
Through expert evaluation, the project has laid the foundation for Xuwei New District to create a national chemical park ecological environment demonstration benchmark, and also provided a demonstration sample for VOCs control in other chemical parks.
VOC Control Examples-Hangzhou: What are solutions for VOCs?
In order to comprehensively fight the battle against air pollution, Hangzhou City actively promotes VOCs volatile organic compounds treatment actions in industrial enterprises.
Organize a training meeting on the upgrading and transformation of activated carbon adsorption facilities, clarify the requirements for technical parameters and indicators of adsorption facilities, and especially emphasize the importance of activated carbon quality.
The city plans to build 3 green island projects to support the “I reduce 1 gram for blue sky” activity. At the same time, it is required to complete the source replacement project of low-VOCs raw and auxiliary materials, the upgrading and transformation of inefficient facilities, and the deep governance project of VOCs in key industries within the specified time.
Through a series of measures, the VOCs treatment level of enterprises has been improved, making positive contributions to ensuring local air quality.
VOC Control Examples-Beijing: Different types of VOCs control
The Tongzhou District Ecological Environment Bureau of Beijing focuses on three major areas to tackle VOCs emission control. How do you manage VOCs?
What is VOC traffic control? In the field of transportation, the inspection of gas stations and oil storage depots has been strengthened. Through the “on-site inspection + off-site inspection” model, the oil and gas recovery system and other systems have been supervised to operate normally and meet emission standards, and many problems have been rectified.
In the industrial field, the unorganized emission problems in key links of petrochemical, chemical and other industries have been targeted, and law enforcement and supervision have been increased to promote the rectification of a large number of problems.
In the field of life, the governance of thousands of catering units has been improved, and the in-depth governance of hundreds of units has been carried out, as well as the assistance and guidance of auto repair companies, to promote the improvement of the refined management level of related industries and the supervision of VOCs emission control.
Activated Carbon For VOCs Volatile Organic Compounds Treatment
These local practices and successful cases fully demonstrate the determination and wisdom of different regions in VOCs governance.
Whether in terms of policy formulation, technology application, or management model innovation, they have provided rich experience for VOCs governance work across the country, inspiring more regions to actively explore governance paths suitable for themselves and jointly promote the continuous improvement of my country’s atmospheric environmental quality.
In future VOCs governance work, activated carbon adsorption technology will continue to play an important role, and strict control of activated carbon quality will also become a key link to ensure governance results.
