Dongfang Boiler Chemical Chain Carbon Capture Equipment System Test Successfully
Recently, Dongfang Boiler, a subsidiary of Dongfang Electric Group, successfully achieved the first successful test of a chemical chain carbon capture equipment system in the world. This technology can directly obtain carbon dioxide with a concentration of more than 90% at the source of combustion and is expected to reduce the cost by two-thirds compared with traditional carbon capture technology. It is a disruptive innovation in the field of carbon capture technology. This technology will provide a new solution for the deep decarbonization of global power, heating, petrochemical, chemical, oil and gas and other industries, and is of great significance to the realization of the "double carbon" goal.
Global climate change caused by carbon emissions is a major challenge faced by mankind. Carbon dioxide produced by fossil energy combustion accounts for more than 80% of carbon emissions. It is the main source of carbon emissions and the main battlefield for carbon reduction. How to adapt to my country's coal-based energy resource endowment, capture carbon dioxide produced by combustion, and store or utilize it is a major and challenging cutting-edge topic.
Chemical looping combustion technology is a new carbon capture technology that is different from traditional technologies. It transfers oxygen in the air to fuel through an oxygen carrier, avoiding direct contact between air and fuel, so that the carbon dioxide produced by combustion is not diluted by nitrogen in the air, thereby achieving self-separation of carbon dioxide at the source of fuel conversion. Chemical looping combustion uses oxygen carriers, for example, like an "oxygen courier", which brings oxygen from the air to fuel for combustion and directly generates high-concentration carbon dioxide, realizing the capture of carbon dioxide from the source. The expected cost is lower than that of traditional carbon capture technology by two-thirds, making it a disruptive new technology for low-cost, high-efficiency, and large-scale carbon capture.
Chemical chain carbon capture technology can internally separate carbon dioxide while maintaining high energy efficiency. In this test, Dongfang Boiler, together with Chinese and foreign cooperative research teams such as Tsinghua University, Total Energy of France, and the French Institute of Petroleum and New Energy, achieved the world's largest fuel heat input of more than 5 MW, and 90% can be directly obtained from the source of combustion. With carbon dioxide above the concentration, the carbon dioxide capture efficiency reaches more than 95%, and the technical indicators are leading the world. This technology has the conditions for gradual commercialization and large-scale application.
Carbon dioxide capture, utilization and storage technology is the main technical approach to reduce carbon emissions in the traditional fossil energy industry. It is a strategic supporting technology to achieve the "double carbon" goal. Once large-scale application is achieved, it will greatly reduce greenhouse gas emissions in the energy industry, providing a strong boost to the realization of the "double carbon" goal. Chemical chain carbon capture technology will provide a key path for thermal power plants to carry out large-scale carbon dioxide capture, thereby promoting thermal power plants to further achieve "zero carbon emissions" on the basis of ultra-low emissions of pollutants, so that thermal power can also become "double zero emissions" green energy. Chemical chain carbon capture technology can also be applied to large-scale carbon capture in high-emission industries such as heating, petrochemicals, chemicals, oil and gas. It has significant environmental and social benefits, and is important for promoting large-scale industrial decarbonization and achieving "double carbon" The goal is of great significance.
