Technical Requirements of Environmental Protection Policy for VOC Emission Reduction of MIBK Production Enterprises?

Technical Requirements of Environmental Protection Policy for VOC Emission Reduction in MIBK Production Enterprises

with the continuous strengthening of China's environmental protection policy, the concept of green development has gradually taken root in the hearts of the people, and chemical enterprises are facing more and more stringent environmental protection requirements. As an important industrial solvent and chemical, MIBK (methyl isobutyl ketone) will produce a large number of volatile organic compounds (VOCs) in the production process, which will not only cause pollution to the environment, but also may be harmful to human health. Therefore, how to achieve VOC emission reduction in the production process has become an important technical challenge for MIBK manufacturers. Based on the requirements of environmental protection policy, this paper analyzes the technical path of MIBK production enterprises in VOC emission reduction.

Background and Requirements of 1. Environmental Policy for VOC Emission Reduction

in recent years, the national and local governments have issued a series of environmental protection policies aimed at reducing VOC emissions in industrial production and improving the quality of the atmospheric environment. According to the "Air Pollution Prevention and Control Action Plan" and the "Twelfth Five-Year Plan for Air Pollution Prevention and Control in Key Areas", VOCs, as one of the main pollutants, are included in the scope of key supervision. MIBK production enterprises as VOC emissions "big", must strictly abide by the relevant laws and regulations, take effective measures to reduce VOC emissions.

Specifically, the environmental policy puts forward the following requirements for MIBK manufacturers:

1. VOC Emission Limits: Enterprises must meet the national or local VOC emission concentration limits.
2. End-of-End Governance enterprises are required to install efficient VOC treatment equipment to ensure emission standards.
3. whole process management from raw material procurement, production process to product storage and transportation, enterprises need to establish a complete environmental management system.
4. information disclosure enterprises need to regularly disclose VOC emission data and accept public supervision.

These policy requirements not only point out the direction for the environmental protection work of enterprises, but also provide an opportunity for technological transformation and industrial upgrading.

2. Technical Path of VOC Emission Reduction in MIBK Production Enterprises

according to the characteristics of VOC emission in the production process of MIBK, enterprises need to take comprehensive measures to reduce emissions. Here are some of the main technology paths:

1. Source emission reduction technology of VOC

source emission reduction is the most effective way to control VOC, mainly through the optimization of production processes and the use of environmentally friendly raw materials to reduce the amount of VOC generated.

• green production process: Use low-VOC or VOC-free production processes, such as switching to environmentally friendly solvents or catalysts, to reduce the generation of VOC during the reaction.
• Closed operation: Reduce VOC emissions through equipment sealing and piping optimization.

2. VOC recovery and treatment technology

for VOC emissions that cannot be completely avoided, companies need end-of-life treatment through recycling and treatment technologies.

• adsorption recovery technology: The use of activated carbon and other adsorption materials to capture VOC, the adsorption of the material can be reused or harmless treatment.
• absorption method water or a specific solvent is used to absorb VOC, and the separated solvent can be recycled.
• membrane separation technology the use of membrane permeability separation of VOC, suitable for high concentration of VOC recovery.
• catalytic combustion technology: The VOC is burned and decomposed under the action of a catalyst to generate carbon dioxide and water.

3. Online monitoring and management

in order to ensure the effectiveness of VOC emission reduction measures, enterprises need to be equipped with online monitoring equipment to monitor VOC emissions in real time.

• Online Monitoring System (AMS) installation of VOC online monitoring equipment, real-time feedback of emission data, convenient for enterprises to adjust process parameters in time.
• data management platform: Optimize emission reduction strategies and improve governance efficiency through big data analysis.

Challenges and solutions in the implementation of 3. MIBK manufacturers

although the environmental policy provides a direction for VOC emission reduction, in practice, MIBK manufacturers still face some challenges.

1. The double pressure of technology and capital

VOC emission reduction technology investment is larger, especially for small and medium-sized production enterprises, capital and technology are the main obstacles.

• Technical upgrade support the government can provide subsidies for technological transformation to encourage enterprises to introduce advanced VOC governance technology.
• Localization of equipment: Through technology research and development, reduce the import dependence of high-end treatment equipment, reduce the cost of enterprises.

2. Improvement of management level

some enterprises lack of professional environmental management team, unable to effectively implement VOC emission reduction measures.

• Training and communication regularly hold environmental protection technical training to enhance the environmental awareness and governance ability of enterprise managers.
• fine management: Realize the environmental management of the whole production process through information technology.

3. Monitoring and improvement of law enforcement

at present, the environmental monitoring and law enforcement in some areas are insufficient, which affects the implementation effect of the policy.

• Strengthen law enforcement: Severe penalties for companies that exceed emissions standards to form an effective deterrent.
• Improve the monitoring network: Build more environmental monitoring sites in key industrial areas to achieve precise supervision.

Prospects for the future development of 4.

With the continuous upgrading of environmental protection policies, the technical requirements of MIBK manufacturers in VOC emission reduction will be more stringent. In the future, enterprises need to start from the following aspects to achieve sustainable development:

1. technological innovation: Increase investment in research and development, the development of more efficient, low-cost VOC control technology.
2. management level promotion: Improve emission reduction efficiency through intelligent and refined management.
3. combination of policy and market make full use of the country's environmental protection policies and achieve emission reduction targets through market mechanisms.

The technical requirements of environmental protection policy for VOC emission reduction of MIBK production enterprises are not only the inevitable choice of enterprise development, but also the need of social sustainable development. Only by actively responding to policies and embracing technological innovation can enterprises remain invincible in the fierce market competition.
