Carbon footprint optimization path of bisphenol A production under carbon neutral target

as the global carbon neutral target is vigorously promoted, the chemical industry is facing the pressure of emission reduction and transformation challenges. As an important basic chemical raw material, bisphenol A(BPA) is widely used in the production of polycarbonate (PC), epoxy resin and other materials, and the carbon emission in the production process has attracted much attention. How to optimize the carbon footprint of bisphenol A production under the goal of carbon neutrality has become the key direction of industry research and practice. This paper will analyze the carbon footprint optimization path of bisphenol A production from multiple dimensions such as raw material substitution, process optimization and energy structure transformation.

Main sources of carbon footprint of bisphenol A production in 1.

The production of bisphenol A is mainly generated by the condensation reaction of phenol and acetone, and its production process involves many links, including raw material acquisition, reaction process, separation and purification. From the perspective of carbon emissions, the carbon footprint of bisphenol A production mainly comes from the following aspects:

1. carbon emissions from raw materials: The main raw materials of bisphenol A are phenol and acetone. The production process of these raw materials usually involves the use of fossil fuels, especially oil refining and ethylene production.
2. Energy consumption the production process of bisphenol A requires a lot of energy for heating, reaction and separation, and the traditional process mainly relies on fossil energy, resulting in high carbon emissions.
3. Process the traditional production process of bisphenol A is more mature, but the reaction conditions are harsh, the energy consumption is high, and the side reaction is more, which further increases the carbon emission.
4. Waste disposal: Waste generated in the production process, such as residue and gas, if not handled properly, will also cause secondary pollution to the environment.

In view of the above problems, optimizing the carbon footprint of bisphenol A production can reduce carbon emissions from the source, while improving process efficiency and energy utilization.

1. Optimize the source of raw materials and promote the green supply chain

the greening of raw materials is an important link to reduce the carbon footprint of bisphenol A production. Companies can optimize raw material sources:

• replacing fossil raw materials with renewable resources: Reduce dependence on fossil fuels through bio-based phenol or acetone production. For example, biorefinery technology is used to produce phenol and acetone from vegetable oils or biomass, thereby reducing the carbon footprint of the feedstock.
• Optimize the reaction path explore new chemical reaction pathways to reduce dependence on high-carbon-emitting raw materials. For example, the development of more efficient catalysts allows the reaction to proceed at lower temperatures and pressures, reducing energy consumption and carbon emissions.
• circular economy model: Introduce the concept of circular economy in the supply chain, use waste plastics, waste epoxy resin and other materials to recover and prepare bisphenol A, and reduce the dependence on virgin materials.

2. Optimize energy structure and promote low-carbon production

energy is one of the main sources of carbon emissions in the production of bisphenol A. Optimizing the energy structure is the inevitable choice to achieve low-carbon production:

• use of renewable energy: The introduction of renewable energy sources such as wind and solar energy in the production process to replace traditional fossil fuels. For example, a distributed photovoltaic power generation system in the construction plant provides clean electricity for production.
• energy cascade utilization: Through cogeneration technology, the waste heat generated in the production process is recycled for power generation or heating, which improves energy efficiency and reduces carbon emissions.
• Energy Management Optimization: Through the intelligent energy management system, real-time monitoring of energy consumption in the production process, optimizing production parameters, and reducing unnecessary energy waste.

3. Process technology innovation to reduce carbon emissions

process technology innovation is the core driving force for low-carbon production of bisphenol A:

• development of low emission process technologies to study the new bisphenol A production process to reduce carbon emissions in the reaction process. For example, the use of autoclave reactors instead of traditional autoclave reactors reduces reaction pressure and energy consumption.
• optimization of reaction conditions: By optimizing the reaction temperature, pressure and catalyst, the reaction efficiency is improved, and the side reaction is reduced, thereby reducing carbon emissions.
• Reduced production of by-products by improving the process design, the production of by-products in the production process is reduced, and the carbon emission caused by waste treatment is reduced.

4. Application of carbon capture and storage technology

carbon capture and storage (CCS) technology, as an important means of combating climate change, can play an important role in the production of bisphenol A:

• flue gas carbon capture: In the production process, carbon dioxide in the exhaust gas is captured and stored through carbon capture technology to reduce direct emissions.
• Carbon sequestration and utilization: The captured carbon dioxide is stored underground, or converted into useful chemicals (such as methanol, carbonate, etc.) to achieve resource utilization.

Prospects of Bisphenol A Production under the Target of Carbon Neutrality in 3.

With the gradual advancement of carbon neutrality goals, the bisphenol A industry will face stricter environmental requirements and technological changes. Enterprises need to actively respond to the challenges, seize the opportunities, and promote the low-carbon transformation of the production process. In the future, the carbon footprint optimization of bisphenol A production will show the following development trends:

1. comprehensive application of green raw materials: With the improvement of technology, bio-based raw materials and circular economy models will occupy a more important position in the production of bisphenol A.
2. Large-scale application of renewable energy the company will accelerate the pace of renewable energy construction and realize the comprehensive low-carbon production process.
3. intelligent production management with the help of industrial Internet and big data technology, intelligent management of the production process is realized to further reduce carbon emissions and energy consumption.

4. Conclusion

driven by the goal of carbon neutrality, the optimization of the carbon footprint of bisphenol A production has become an important direction for the transformation and upgrading of the industry. By optimizing the source of raw materials, promoting the transformation of energy structure, strengthening process technology innovation and applying carbon capture technology, enterprises can improve their competitiveness in achieving low-carbon production. In the future, with the continuous breakthrough of green technology and the increase of policy support, the bisphenol A industry is expected to achieve sustainable development under the goal of carbon neutrality.
