Give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development in Chemical Engineering Equipment】Ongoing updates and summaries available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Hangyang’s 110,000 cubic meter air separation unit has been operating steadily at the world’s largest coal-based olefin project for over 4,800 hours! 2025-07-14 At present, the world’s largest coal-based olefin project is operating efficiently. Its core \"power source\" – a set of air separation units of 110,000 capacity, the largest of their kind in any single plant, provided by Hangyang Group – has been running steadily for over 4,800 hours! Experts unanimously agree that this project has set new industry records in terms of production capacity, construction time, equipment replacement, and energy consumption costs. Its technological level is far ahead of that in the international arena, serving as a model that can be used as a reference for achieving a deep integration of large-scale operations with industrialization in the coal chemical industry. As an indispensable \"lungs of industry\" for the project, the 6 sets of extra-large air separation units of 110,000 capacity provided by Hangyang represent the largest in scale and highest in domestic production rate among the air separation units currently in operation in China. From October 2024 to March 2025, six 110,000-ton-class air separation units were brought online one after another to produce oxygen, supporting the steady operation of the world’s largest olefin plant and large-scale green hydrogen-based olefin production projects. With a sense of mission akin to that of a \"team,\" Hangyang, backed by its world-class design and manufacturing capabilities as well as professional and efficient technical services, ensured that the project was put into operation on schedule, with high quality and stability. The air separation unit utilizes advanced distillation tower manufacturing technology developed independently by Hangyang. It incorporates key components such as high-pressure aluminum plate-fin heat exchangers and large-diameter molecular sieve three-bar valve switches. Moreover, the unit is deeply integrated with digital and intelligent technologies, enabling real-time monitoring and full-process tracking through an intelligent operation center, thus demonstrating its strong capabilities in intelligent manufacturing. In projects of similar scale, the \"Hangyang solution\" has set a new benchmark for efficiency in the industry, thanks to its significant advantages of short design and manufacturing cycles, high degree of localization, and top-tier technical standards. Through continuous independent innovation, Hangyang has taken the lead in mastering the 150,000-class air separation manufacturing technology, which represents the world’s highest standard, and is showing strong growth momentum in the field of ultra-large-scale air separation. Its market share in the global air separation equipment sector remains leading; a total of 146 units of air separation equipment rated at 60,000 units or higher have been sold, and 31 units rated at 100,000 units or higher. To date, the total amount of gas supplied by Hangyang to Baofeng Group has exceeded one million cubic meters. In the future, Hangyang will continue to use innovation as its driving force to contribute significantly to its **strategic goals!
