Successful Commissioning of the Turbine in Unit C of the Air Separation Unit at Inner Mongolia Rongxin Project by Hualu Technology Author/Source: Hualu Engineering Technology Co., Ltd. Date: July 24, 2019 Views: 32 On July 11, the turbine in Unit C of the air separation unit at the Inner Mongolia Rongxin project, developed by Hualu Engineering Technology Co., Ltd., reached a speed of 4,573 revolutions per minute; the turbine was commissioned successfully, and the testing phase of the air separation unit progressed rapidly. The turbine is the core equipment of the air separation unit, responsible for providing power to compressors, boosters, and other devices. The successful commissioning this time marks another important milestone achieved for the Inner Mongolia Rongxin project, laying a solid foundation for the oxygen and nitrogen production by the air separation unit. Both air separation units in the Rongxin project utilize technology from the French company Air Liquide. Each unit has an oxygen production capacity of 92,000 Nm3/h; it supplies high- and low-pressure oxygen, low-pressure nitrogen, process air, and instrument air to downstream processes. Additionally, liquid nitrogen and liquid argon are produced as by-products. These units feature automatic load adjustment, a long service life, low energy consumption, and a high oxygen extraction efficiency. To ensure the successful completion of this turbine startup process, the Inner Mongolia Rongxin project team organized everything carefully and coordinated closely with the client, patent holders, suppliers, civil engineering and installation contractors, as well as anti-corrosion and insulation teams. By overcoming various challenges, they completed tasks such as pressure testing and purging of the P91 pipelines, mechanical and electrical commissioning of the turbine units, oil circulation tests, instrument logic tests, and trial operations of the individual units and auxiliary systems. Through the \"three inspections and four determinations\" approach, they identified and resolved various issues in a timely manner, thus laying the groundwork for a smooth turbine startup.
