Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Continuous updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** “Shenmu Intelligent Manufacturing” contributed to the successful commissioning of the world’s largest coal-fired power plant carbon capture project. On September 25th, the world’s largest coal-fired power plant carbon capture demonstration project completed a 72-hour trial operation at Huaneng Gansu Zhengning Power Plant and was officially put into operation. Shenmu Group developed a customized set of core driving equipment for this project – the first system solution in China for an eight-stage, fully gear-driven centrifugal compressor unit. This solution enabled the highest flow rate and pressure of carbon dioxide gas among similar demonstration projects in China, once again demonstrating Shenmu Group’s technical expertise and its role as a key player in China’s industrial sector. It is reported that this project is a **major science and technology demonstration project as well as one of the first batch of green and low-carbon demonstration projects approved by the National Development and Reform Commission. Its carbon dioxide capture rate exceeds 90%, with the purity of the captured carbon dioxide reaching over 99%. It is capable of capturing 1.5 million tons of carbon dioxide per year, which is equivalent to the annual carbon emissions from 600,000 cars. This capability helps coal-fired power plants achieve large-scale, industrialized deep emission reductions, thereby promoting the green and clean development of coal-based power generation. Focusing on key aspects such as carbon capture, compression, and storage, this project has overcome various technical barriers, including those related to energy-efficient supercritical carbon dioxide compressors. It has achieved multiple \"world firsts\" and \"national firsts\", with 100% localization of the core equipment. Not only has it filled gaps in this industry, but it has also raised China’s CCUS technology to a world-leading level, setting a new benchmark for the low-carbon transformation of the coal power sector. Faced with the new challenges posed by carbon capture on a million-ton scale, and leveraging its extensive technical expertise in high-end centrifugal compressors, SHENGU collaborated with Huaneng Qingneng Research Institute to develop a customized solution for this project. As a result, China’s first eight-stage, multi-axis carbon dioxide compressor was created; through eight stages of compression, the volume of carbon dioxide is reduced to 1/300 of its original size – in other words, a cotton bale the size of a truck is compressed to the size of a brick, thereby making subsequent transportation and storage more efficient. During the development process, Shenyang Drum Group took into account the project’s overall carbon reduction goals and the requirements for green development. It carefully weighed factors such as cost-effectiveness, efficiency, and power consumption, and carried out extensive preliminary research and experimental testing on potential solutions. By using specialized models developed for supercritical carbon dioxide, conducting rotor dynamics analyses, optimizing axial thrust, and establishing a closed-loop testing system, the group achieved a series of significant technical breakthroughs, set multiple records, filled gaps in China’s capabilities in this field, and played an important role as a model for others to follow. The full operation of the world’s largest coal-fired power carbon capture demonstration project marks a historic leap for China’s CCUS technology, moving it from \"ten-thousand-ton scale demonstrations\" to \"million-ton scale industrial applications.\" It also signifies a new breakthrough by Shengli Heavy Industry Group in terms of its design and manufacturing capabilities for core equipment related to carbon capture, utilization, and storage. Looking to the future, SHENGU Group will closely focus on the further implementation of the **\"dual carbon\" strategy, continue to drive innovation in technology, and deepen its efforts in its core business. It will work to make its products more advanced, intelligent, and environmentally friendly, thereby providing solid equipment support for energy security and the transition toward a green, low-carbon economy. The group will also contribute to global environmental protection and climate governance through its efforts.
