On December 30, the core unit of the Gansu Juhua New Materials Co., Ltd. high-performance silicon-fluorine new materials integrated project, namely the air separation cold box – part of the air separation and air compression station equipment package (including detailed design, installation, and commissioning) undertaken by China Air Separation Engineering Co., Ltd. (hereinafter referred to as “China Air Separation”) (hereinafter referred to as the “Gansu Juhua project”) – was successfully completed. The completion of this critical milestone marks the successful completion of the task of lifting the project’s core equipment, thereby signaling the start of subsequent equipment installation, testing, and commissioning. At this crucial moment at the end of the 14th Five-Year Plan period, it represents a chapter of hard work and determination in overcoming challenges. As a core component of Gansu Juhua’s fluorine synthesis industry and one of the key equipment in the air separation unit, the air separation cryogenic tank plays a vital role in supplying high-quality industrial gases such as oxygen, nitrogen, argon, and instrument air to the production lines. This device utilizes advanced and reliable intelligent cryogenic separation technology, offering significant advantages such as low energy consumption, stable operation, and a high degree of automation. Its successful completion is crucial for the progress of the entire project. The total weight of the air separation cryogenic tank is 174 tons. To ensure the successful lifting of this massive structure, the project team devised a careful plan and implemented scientific strategies, using a 700-ton main crane and a 130-ton mobile crane to work together in order to lift the tank in three sections. As the upper section of the cryogenic tank was smoothly lifted to a height of over 60 meters above the ground and precisely connected to the lower section, the lifting operation was completed successfully, and the task of completing the construction of the cryogenic tank was fulfilled with success.
