【Ten Years of Rapid Development in Chemical Engineering Equipment】869–2023: Harbin Boiler Group’s construction of the 40·60 project – 437-ton ammonia synthesis tower for New Hengsheng Company

Thread Content

Ten years of rapid development in chemical processing equipment – praise for the prosperous and strong China. This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with your involvement; we welcome everyone to join in the forum discussions and exchanges. ********************************************* Hagao manufactured the 437-ton ammonia synthesis tower for New Hengsheng Company’s 40·60 project. On March 11, 2023, after another lift by the crane on site and 240 minutes of installation and debugging, the shell of the synthesis tower was successfully placed in its designated position, marking the official installation of this tower in New Hengsheng Company’s 40·60 project’s synthesis facility. The ammonia synthesis tower consists of two parts: the internal components of the tower and its outer shell. Among them, the internals of the ammonia synthesis tower are manufactured by Casali of Switzerland, while the casing is produced by Harbin Boiler Factory Co., Ltd. The synthesis tower shell is currently the heaviest piece of equipment for single-unit transportation and lifting in installation projects; its net weight, excluding the heavy cover, is 437 tons, with a length of 30.805 meters. Not only is it difficult to transport this equipment, but lifting it on-site is also extremely challenging; its foundation is located 10 meters above the height of the ammonia synthesis framework platform. The lifting operation was carried out using an 800-ton crawler crane as the main crane, with a 400-ton crawler crane serving as an auxiliary crane; the steel cables of the 800-ton main crane and those of the 400-ton auxiliary crane were attached to the lifting lugs on the shell of the synthesis tower, allowing it to be lifted vertically, raised gradually, lowered slowly, aligned, and brought into proper position... At 2:30 p.m., the shell of the synthesis tower was successfully placed on the platform foundation, and the lifting and positioning task was completed successfully.
