VOCs Waste Gas Recycling Treatment Process

VOCs mainly come from petrochemicals, electronic manufacturing, and automobile exhaust. Some VOCs have strong toxicity or carcinogenicity, posing a serious threat to human life and health. At present, VOCs are increasingly becoming an important component of air pollution, causing significant damage to the environment. What are the VOCs waste gas treatment processes.

There are various methods for removing VOCs, and adsorption method has the advantages of high efficiency, low energy consumption, simple operation, and recyclability, making it an effective technology for removing VOCs.

Organic adsorbent

Organic adsorbents mainly refer to polymer adsorption resins, which are a type of porous, highly cross-linked polymer characterized by adsorption and have the ability to concentrate and separate organic matter.

Adsorption resins are mainly divided into gel type and macroporous type. Macroporous adsorption resins are widely used at present. With the emergence of macroporous ion exchange resins, macroporous adsorption resins have been developed.

Adsorption resin is very similar to activated carbon in terms of adsorption performance, and most of them can be quantitatively adsorbed and reused. Although activated carbon has good adsorption performance, regeneration is often difficult.

There are currently over 200 brands of adsorption resin products, and they are constantly increasing. According to the surface properties of resins, adsorption resins are generally divided into four categories: non-polar, medium polar, polar, and strongly polar.

Haipu Organic Waste Gas Treatment Solution

Jiangsu Haipu Functional Materials Co., Ltd. is a high-tech enterprise dedicated to the research and development of high-performance adsorbents, catalysts, and their process applications.

With a series of independently developed high-performance adsorbents and catalysts as the core, combined with independently developed process technology, Haipu has become a professional solution provider in the fields of environmental governance and resource recycling. At the same time, taking it as our responsibility to help industrial enterprises meet environmental standards and achieve sustainable development through resource utilization, we adopt modular lean production and develop engineering solutions based on research and development data.

According to the "Technical Specification for Industrial Organic Waste Gas Treatment by Adsorption Method", the process of adsorption regeneration recovery can be used for recyclable organic waste gas, and the process of adsorption concentration combustion can be used for non recyclable organic waste gas. Based on the characteristics of these organic waste gases, a series of special adsorption materials and application processes have been developed to achieve effective treatment and resource recovery of various VOCs.

The technological advantage lies in: 1. It can flexibly combine relevant processes according to the characteristics and treatment requirements of different organic waste gases, achieving efficient resource utilization and treatment of waste gases; 2. The adsorbent material has a high specific surface area, large adsorption capacity, high mechanical strength, and can be repeatedly regenerated and used.

The solution is applied to the treatment and recovery of volatile organic gases generated in chemical plants, electronics plants, printing plants, paint workshops, coating plants, etc.

For example, in the treatment of exhaust gas generated by a pharmaceutical factory using dichloromethane as a solvent, the exhaust gas emission is 500 cubic meters per hour, and the dichloromethane content is about 90%. After treatment, the effective recovery of dichloromethane exhaust gas is achieved, providing protection for the subsequent RTO system; The recovery efficiency of dichloromethane reaches 95%, and the annual value of recovered resources is about 500000 yuan.

Epilogue

The harm of VOCs to the environment and the threat to human health have attracted widespread attention from the public, and their governance is urgent.

In the technology of VOCs pollution control, adsorption is one of the effective and economical technologies, and adsorbents are the key to treating VOCs pollution. However, current adsorbents still have disadvantages such as low adsorption efficiency at high temperatures and inhibition of VOCs adsorption at high humidity. Therefore, further improving the adsorption capacity and efficiency of existing adsorption materials through surface modification, adjusting pore structure, and composite of various materials to develop more efficient and green adsorption materials is the future research direction.
