Lansi Heavy Equipment undertook the task of manufacturing 19 large-scale equipment units for this project, including methanol recovery towers, alcohol removal towers, ethylene glycol production towers, MN regeneration towers, DMO gas removal towers, nitric acid reduction towers, as well as gas collection tanks for DMO reactor purging processes and No. 1 nitrogen storage tanks. The total weight of these equipment units is 3,651 tons; their maximum diameter is 8.5 meters, and their maximum height is 77 meters. All of them are made of large-diameter, thin-walled composite materials. Components such as equipment connection flanges and external pre-welded parts are manufactured by Lanshi Heavy Equipment Reconstruction Xinjiang Company ； The cylinder is rolled, the longitudinal and circumferential seams are welded together, and components such as nozzles and internal parts are assembled and welded. Processes such as pressure testing and pickling for corrosion protection are carried out on-site by the Mobile Factory Division of Lanshi Heavy Equipment Installation.
