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】Regular updates and summaries are available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html *****************Recently, the exhaust gas compression unit for carbon dioxide capture, provided by Shanggu for the 400,000 tons per year CCS demonstration project at Shaanxi Coal Group Yulin Chemical Co., Ltd., passed its initial test successfully. This marks an important breakthrough in key technical equipment related to CCS (carbon capture and storage) in China, and it also provides a solid foundation for the steady progress of this project. Located in Yulin, Shaanxi, this project is currently the largest CCS project in China. The project focuses on the advanced, diversified, and low-carbon development of the coal chemical industry, and is divided into three phases, with the goal of ultimately creating a **-level CCS demonstration model characterized by technical autonomy, large-scale engineering implementation, commercial operation, and replicable business models. Among them, the pilot test project can achieve an annual reduction of 400,000 tons of CO2 emissions, which is equivalent to adding 400,000 mu of forest area; it provides an industrial-grade test platform for large-scale CO2 sequestration in aquifers across the country. The unit that succeeded in this test is a 15MPa-class single-stage centrifugal CO? compressor independently developed by Shaanxi Gas Turbine. This unit is the first high-pressure centrifugal carbon dioxide compressor in China to be applied in CCS systems. The overall compression ratio exceeds 120, and the pressure difference is over 140 bar; the high exhaust pressure and high exhaust density impose almost stringent requirements on the long-term operational stability and reliability of the unit. The technical team at Shaanxi Blower Group faced the challenges head-on and successfully overcame numerous difficulties related to the compression of high-pressure, high-density media. These innovative technologies significantly enhance the stability and overall reliability of long-term operation of the units, ensuring a proper match between the units and the process systems. The successful test run of the unit not only marks a crucial breakthrough for the project, but also carries multiple responsibilities, including driving the industry’s green transformation, achieving independent technological innovation, and contributing to the achievement of the **\"dual carbon\" goals. An operational and replicable path for low-carbon transformation has been explored for coal chemical enterprises. CCS is one of the key technologies for addressing climate change and achieving carbon neutrality goals; it aims to reduce carbon dioxide emissions through technological innovation and engineering practices, thereby promoting economic and social development in a low-carbon and sustainable direction. At the heart of CCS projects are CO2 compressors. Over the years, Shaanxi Blower has been actively working in this field, accumulating technical advantages as well as a track record of reliable operation in various applications. Currently, SHANGGU’s CO2 compressors are used in CCS plants with capacities of 300,000–1 million tons per year and an exhaust pressure of less than 15 MPa; tailored and reliable solutions are provided to meet the needs of various users. In the future, Shaanxi Blower will continue to be driven by technological innovation, focusing on green and low-carbon development as well as energy conservation and emission reduction, so as to contribute its expertise and efforts to advancing the industry and economic development.
