Carbon footprint optimization path of production process under carbon neutral target

in the context of the intensification of global climate change, the goal of carbon neutrality has become the focus of attention of various industries around the world. As an important pillar of the national economy, the chemical industry is also a major carbon emitter. How to optimize the carbon footprint of the production process has become an important issue for the industry to achieve sustainable development. This paper will analyze the specific methods of carbon footprint optimization in the chemical industry under the carbon neutral target from the perspective of optimization path.

1. refactoring the production process: from the source to reduce carbon emissions

The reengineering of the production process is the first step to optimize the carbon footprint. Traditional chemical production processes are often characterized by high energy consumption and high emissions. With the advancement of technology and the renewal of concepts, carbon emissions can be reduced from the source through process optimization and structural reorganization. For example, the use of modular production technology can reduce the energy consumption of intermediate links; through process integration, the cascade utilization of energy can be realized, thereby reducing overall carbon emissions.

The application of the concept of green chemistry also provides a new idea for the reconstruction of the production process. By designing more efficient and environmentally friendly chemical reaction pathways, reliance on high carbon-emitting processes can be reduced at the source. For example, the use of catalytic technology instead of traditional high-temperature and high-pressure reactions can not only reduce energy consumption, but also reduce carbon emissions.

2. application of low-carbon technologies: promoting production process upgrading

The application of low-carbon technology is the core driving force to realize the optimization of carbon footprint. In the chemical production process, the carbon emission intensity can be significantly reduced by introducing advanced low-carbon technology. For example, the application of renewable energy, such as solar energy and wind energy, can replace traditional fossil energy, thereby reducing carbon emissions. The application of water electrolysis hydrogen production technology also provides new possibilities for reducing carbon emissions.

In addition, the optimization of the carbon footprint of the chemical industry can also be achieved through technological transformation and equipment upgrading. For example, the use of high-efficiency heat exchangers, energy-saving boilers and other high-efficiency equipment can significantly reduce energy consumption, thereby reducing carbon emissions. Through the application of intelligent technologies, such as the Industrial Internet of Things (IIoT) and big data analytics, real-time monitoring and optimization of production processes can be achieved to further improve energy efficiency.

3. Building a Circular Economy System: Realizing Resource Efficient Utilization

The construction of circular economy system is an important way to realize the optimization of carbon footprint. In the chemical production process, through the recycling of resources, the consumption of raw materials and waste emissions can be minimized. For example, the recycling of waste materials can be used to convert waste plastics and rubber into new chemical raw materials through chemical recycling technology, thereby reducing dependence on fossil resources.

The cascade utilization of energy is also an important part of building a circular economy system. By using high-grade energy for the high-temperature process and low-grade energy for the low-temperature process, energy efficiency can be significantly improved, thereby reducing carbon emissions. For example, in the petrochemical industry, waste heat from refineries can be used for steam power generation, thereby achieving efficient use of energy.

4. data driven and intelligent: future optimization direction

With the development of artificial intelligence and big data technology, data-driven optimization methods will become an important direction for carbon footprint optimization in the future. By building a carbon emission monitoring and management system, the carbon emission data in the production process can be monitored in real time, and the path to minimize carbon emissions can be found through data analysis and optimization algorithms. For example, machine learning models are used to predict energy consumption and carbon emissions in the production process to optimize production process parameters.

The concept of smart factories also provides new ideas for carbon footprint optimization. Through intelligent production management, precise control of the production process can be achieved, thereby reducing energy waste and carbon emissions. For example, smart sensors and automated control systems can adjust production parameters in real time to adapt to different operating conditions, thereby maximizing energy efficiency.

5. Conclusion

The realization of the goal of carbon neutrality is inseparable from the active participation of the chemical industry. By reconstructing the production process, applying low-carbon technologies, building a circular economy system and promoting intelligent transformation, the chemical industry can reduce carbon emissions from the source and optimize the carbon footprint of the production process. In the future, with the continuous advancement of technology and the continuous updating of concepts, the chemical industry will surely achieve higher quality development under the goal of carbon neutrality.
