The second compressor unit for the air separation plant at Ningxia Baofeng passed its trial run at SHENGU Group’s Yingkou facility. Author/Source: Gas Separation. Date: November 20, 2019. Clicks: 20. On November 19, following the command to shut down the system, the second compressor unit (air compressor) designed by SHENGU Group for Ningxia Baofeng Group, with a capacity of 105,000 Nm3/h, successfully completed its trial run at SHENGU Group’s Yingkou facility! Operational data show that all mechanical and aerodynamic performance indicators of the unit meet the design requirements. The first unit of this plant (the air compressor) was successfully tested on November 8! In January 2018, SHENGU Group signed a contract with Ningxia Baofeng Group for two sets of 105,000 Nm3/h air separation compressors. This marked another achievement in the localization of complete air separation equipment of this capacity, following SHENGU Group’s completion of the task of producing China’s first set of compressors for 100,000 Nm3/h air separation units in 2013. Dai Jishuang, chairman of SHENGU Group, said at the signing ceremony: “SHENGU is committed to ensuring product quality and on-time delivery, striving to create world-class premium air separation projects.” Provide comprehensive services throughout the project’s lifecycle, eliminate Baofeng’s concerns, and serve as a strong backing for the stable, efficient, and continuous operation of Baofeng’s air separation units and various process facilities, thereby contributing to the development of the Baofeng Group. ” Shenmu Group is a pillar and strategic leader in China’s major technical equipment industry. It produces three main categories of products: various centrifugal and axial flow large-scale compressors, reciprocating compressors, and various industrial (nuclear power) pumps. The company is responsible for supplying domestically produced equipment for important national projects in areas such as petroleum, chemicals, air separation, power generation, and metallurgy, which are crucial to the country’s economy and people’s livelihoods. The successful trial operation of this 105,000 Nm3/h air separation unit signifies that Shenyang Gas Turbine Group has reached a leading level in China and an advanced level internationally in the field of air separation compressor design and manufacturing! A look back at the development of domestic \"Chinese cores\" for large-scale air separation units * At the end of 2011, Shengli Heavy Machinery Group, leveraging the \"Shenhua Ningxia Coal-to-Oil Project\", embarked on research and development efforts to create domestically produced air separation compressors of 100,000 capacity. Through extensive and meticulous work in line with the plans for large and super-large air separation compressor systems, a solid foundation was laid for the successful development of 100,000 Nm3/h air separation compressor units! * In 2012, the **Energy Bureau approved Shengli Blower Group to undertake** the construction of the \"R&D (Experimental) Center for Large Turbine Compressor Units\" project, allocating 700 million yuan to build the only such facility of its kind in China and one of the most advanced in the world at the Yingkou site – a test bench with a capacity of 100,000 kilowatts. * In 2013, SHENGU Group won the bid for one of the compression units in the \"Shenhua Ningxia Coal 4 million tons per year Coal Indirect Liquefaction Project.\" Together with Hangzhou Oxygen and Hangzhou Steam Turbine, it formed a joint task force that helped to enable the operation of this super-large air separation unit using domestically developed technology! * At the beginning of 2015, the 100,000 Nm3/h air separation compressor unit was introduced to the market, making its debut! * On August 23, 2015, the 100,000-class air separation compressor unit, measuring 35 meters in length, 15 meters in height, and weighing 478 tons, passed the factory acceptance inspection by an expert panel thanks to its excellent performance. * On May 15, 2017, the joint commissioning was completed successfully; the unit operated smoothly, and all its mechanical and aerodynamic performance indicators met international advanced standards. * On August 25, 2017, the air compressor unit for the 100,000 Nm3/h air separation plant passed the industrial operation review, and it was recommended that its use be promoted as soon as possible. * On April 26, 2018, China’s first set of compressor units designed for 100,000-class air separation plants passed the evaluation by an expert panel. The expert group believes that the 100,000-class compression units fill a gap in the domestic market by breaking foreign technological monopolies; the overall performance of these units reaches international advanced levels, with some of their performance indicators being at the international leading level.
