The air separation unit designed and manufactured by Hangyang Company has a production capacity of 83,000 cubic meters per hour, which is sufficient to meet the needs of the Zhoushan Green Petrochemical Base for processing 40 million tons of materials per year. There are four complete cryogenic units, each with a height of 70 meters and a weight of nearly 1,000 tons. Starting from mid-March, four complete refrigerated containers were successively delivered to Yushan Island, and lifting operations began last month; the one lifted this time is the last one. To lift weights of nearly a thousand tons, the main lifting device is this domestic large-scale crane; its boom can reach over 200 meters in length, and it is capable of lifting weights of 4000 tons, earning it the title of the world’s strongest crane. After nearly two hours, the cold box was lifted into place, followed by tasks such as bottom reinforcement and disconnecting the main crane. Thus, all four sets of cryogenic tanks have been installed, and the lifting operation was completed successfully. According to the plan, the equipment will undergo a turbine impact this month, laying the foundation for the commissioning of the entire refining project. ----------------------------------------------------- Everyone is welcome to participate in the following series of sharing discussions; clicking on the link will take you there. -------------------------------------------------------------------------- This is a summary post for the 【Guess the Haichuan Equipment】 series – all equipment enthusiasts are encouraged to join in! https://bbs.hcbbs.com/thread-2079686-1-1.html (Source: Haichuan Chemical Industry Forum) Summary post of the [Haichuan.

This crane operator must be really amazing
It’s better at sea, as the entire structure can be welded first and then lifted; it’s a bit more difficult on land
Tailing behind two vehicles is generally not allowed; it’s very difficult to coordinate such situations. It seems that a proper plan is essential ---------------------------
Guess where this device was made? ? ? ----------------------------------------------------------- @The wise are enlightened @LQ198619
I wonder how much this crane costs per month; it must be at least a million
The ladder railings were installed at the factory
A 20-plus-story cold box has been fully assembled. Air separation equipment separates air at low temperatures to produce products such as oxygen and nitrogen; it is essential production equipment for industries such as metallurgy, petrochemicals, oil, and fertilizers. The cryogenic tank is the most crucial component of air separation equipment; for instance, the liquid nitrogen stored within it has a temperature of -196°C, and its construction and installation are quite complex. “In the past, for the cryogenic tanks of large air separation units, the manufacturer would produce the components first and then transport them to the project site for assembly. ”Dr. Yao Lei, a project engineer at Hangyang, explained that the current approach involves carrying out integrated production in the factory before transporting the equipment to the site. This method not only ensures better quality and compliance with technical standards in equipment manufacturing, but also avoids the limitations associated with on-site assembly areas and construction techniques; it also **helps to save time during project construction. ”This project is the first complete set of equipment in China with a capacity of over 80,000 m3/h, which naturally imposes higher requirements on aspects such as design, production, and transportation. At the scene, the reporter saw that the horizontal bulk container had been loaded onto four large roll-on vehicles. Driven by the rolling traction of dozens of load-bearing tires, the cold box will be slowly pulled to the riverbank, and from there it will be loaded onto a ship for shipment, traveling along the Yangtze River all the way to Yushan Island in Zhoushan, East China Sea. After being lifted into place, this massive structure lying on its side will be turned upright to become a landmark structure over 20 stories tall.
Can domestic manufacturers now produce air separation units of 100,000 m3/h capacity? It seems to have been used in a coal chemical project in Shaanxi.
