At 10:13 on April 1, the Zhejiang Energy Lanxi Carbon Dioxide Capture and Mineralization Integration Demonstration Project, a project under the provincial “Elite” R&D initiative led by Zhejiang Energy KeHuan, which is part of Zhejiang Energy Group, successfully passed a 72-hour operation test. With the arrival of spring in 2024, Happy Forum **********************[A Decade of Development in Chemical Processing Equipment] – Continuous updates and summaries available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Industry Forum Website) ***************** At 10:13 on April 1, 2024, the Zhejiang Energy Lanxi Carbon Dioxide Capture and Mineralization Integration Demonstration Project, carried out under the provincial “Elite” R&D initiative led by Zhejiang Energy KeHuan, passed the 72-hour operation test. This marks the fact that China’s first full-process demonstration project for coal power carbon capture and mineralization is now ready from a technical standpoint to be put into operation. This project is a demonstration project in China that marks the first application of carbon dioxide mineralization aerated block technology in practical engineering. During the continuous operation tests, the project achieved an average carbon capture rate of 90%, with a capture purity of 99%. Two-thirds of the captured carbon dioxide was used for the mineralization and curing of aerated blocks, while the remaining one-third was used for compression and liquefaction to produce food-grade dry ice; thus, 100% of the captured carbon dioxide could be utilized. Saving energy and reducing carbon emissions relies not only on planting trees but also on new forms of productive capacity. Currently, with continuous advancements in carbon dioxide capture, utilization, and storage technologies, China has become one of the world’s largest producers of such technologies. According to the researchers, this project uses a low-energy-consuming two-phase absorbent, with the energy required for its regeneration being less than 2.4 GJ per ton, which is at an internationally advanced level. Zhejiang Energy’s carbon-capture experts are capable of capturing carbon as well as making good use of it. On the dry ice production line of this facility, square blocks of dry ice are neatly arranged and transported from the conveyor belt to the storage area. These dry ice, made from \"captured\" carbon dioxide, is food-grade dry ice that can be used for the cold-chain transportation of food and pharmaceuticals. At the same time, more carbon dioxide will be \"captured\" in mineralized aerated block materials, which can be used in construction and other fields, thereby achieving both environmental and economic benefits. “Baking bricks for construction is actually quite similar to steaming buns; carbon dioxide is used in place of steam, and through a series of chemical reactions, carbon dioxide gets permanently trapped within the bricks. ” Chen Yaoji, director of Zhejiang Energy Science and Environment Research Institute, used simple analogies to explain the key features of the project’s technology. It is reported that the project officially commenced construction at Zhejiang Energy Lanxi Power Plant in March 2022, with a total investment of around 82 million yuan. A technical team composed of Zhejiang Energy Science & Environment, Zhejiang Energy Power, Zhejiang Energy Lanxi Power Plant, Baimahu Laboratory, and Zhejiang University worked together to carry out the project. The designed capacity is to capture 15,000 tons of carbon dioxide per year, which is equivalent to the amount of carbon dioxide absorbed by 15,000 mu of forest each year. “The production and utilization of energy are accelerating their transition toward greener and lower-carbon models. Promoting a green and low-carbon technological revolution in coal-fired power plants is an important factor in achieving carbon peak and carbon neutrality. ”Liu Shenghui, Secretary of the Party Committee and Chairman of Zhejiang Energy Group, said, “Zhejiang Energy Group will take on the role of being the main driver for innovation in energy technology in our province. It will focus on two key tasks: ensuring a high-quality supply of energy and achieving a high-quality green transformation. The group will work together to develop key core technologies, promote the application of research results, and accelerate the development of new forms of productive capacity.” ”
