Introduction to the Treatment of VOC Organic Waste Gas by Haipu Adsorption Method

Recently, the Ministry of Ecology and Environment is further organizing 227 working groups to carry out the second round of strengthened supervision and assistance in 78 cities, guiding and helping local governments and enterprises to effectively reduce VOCs emissions and enhance ozone control capabilities.

And cities such as Hangzhou, Taiyuan, Jining, Zibo, Nantong, and Xuzhou have issued their first VOCs fines.

Volatile organic compounds (VOCs) are important precursors for the formation of ozone. In order to strengthen VOCs control and effectively control ozone pollution, the Ministry of Ecology and Environment has formulated the "2020 VOCs Control Plan".

It is required to carry out a summer (June September) VOCs control campaign nationwide, with chemical, industrial coating, packaging and printing as key areas, vigorously promoting source substitution, using coatings, inks, adhesives, etc. that comply with national regulations on low VOCs content products, effectively reducing VOCs generation.

Relevant documents issued by the Ministry of Ecology and Environment

The chemical industry, as a key industry, has been the focus of various VOC special rectification campaigns. Whether in the production or processing process, if one link does not meet the standard, it will cause VOC emissions to exceed the standard, which will then pollute the environment and cause irreparable damage to the atmospheric environment.

So, how should VOC organic waste gas be treated?

Introduction to the treatment of VOC organic waste gas by Haipu adsorption method

According to the "Technical Specification for Industrial Organic Waste Gas Treatment by Adsorption Method", the process of adsorption regeneration recovery can be used for resourceful organic waste gas, while the process of adsorption concentration combustion can be used for non recyclable organic waste gas.

Based on the characteristics of these organic waste gases, Jiangsu Haipu Functional Materials Co., Ltd. has developed a series of special adsorption materials and application processes, which can achieve effective treatment and resource recovery of various VOCs.

Application effect of Haipu VOCs adsorbent products

A certain chemical enterprise uses Haipu VOCs adsorbent for adsorption treatment of 2000m³/h dichloromethane waste gas, which can recover the vast majority of dichloromethane components in the waste gas. 1296kg of dichloromethane can be recovered per day, increasing the economic benefits of the enterprise.

A production workshop of a certain enterprise produces 3000m³/h of dichloroethane waste gas with a concentration of 30000mg/m³

After comprehensively comparing the feasibility, investment and operational economy, convenience and safety reliability of various treatment technologies, the enterprise has decided to use Haipu VOCs adsorbent for adsorption treatment,

After processing, the content of dichloroethane is ≤ 30mg/m³, ensuring that it can be integrated into the subsequent RTO system after exhaust.

Technical advantages of Haipu adsorption method for treating VOC organic waste gas

1. Flexible combination of relevant processes can be carried out based on the characteristics and treatment requirements of different organic waste gases to achieve efficient resource utilization and treatment of waste gases;

2. Adsorbent materials have high specific surface area, high activity/capacity, high mechanical strength, and long service life.
