Guangxi Hengyi New Materials’ steel structure module with a lifting weight of 545 tons

Thread Content

On May 4, 2024, the steel structure modules for sections 56–63 of the gasification unit in the coal-based hydrogen ammonia synthesis plant, as part of Guangxi Hengyi New Materials Co., Ltd.’s project for an integrated production facility capable of producing 1.2 million tons per year of caprolactam and polyamides, were successfully lifted into place. This represents another major milestone in the project, following the lifting of the gasification furnace in that unit; it creates the conditions necessary for the subsequent installation of process pipelines. The total height of the steel structure for the gasification unit is 90 meters; the lifting operation in this case involves two layers of steel structure at heights of 56–63 meters. These structures are divided into three modules, with each module measuring 10 meters by 20 meters. The heaviest module weighs 265 tons, while the total weight to be lifted is 545 tons. On April 25, the gasifier of this project was officially lifted. The gasifier has a diameter of 3.6/4.2 meters, a length of 36.3 meters, a net weight of 508 tons, and a lifting weight of 750 tons. The successful lifting of this gasification furnace represents another major milestone, following the first lifting of the scrubber tower in the purification unit; it signifies yet another substantial advance in the project’s installation work. The integrated hexamethylene imide-polyamide production facility with an annual output of 1.2 million tons, as well as the associated coal-based hydrogen production and ammonia synthesis units at Guangxi Hengyi New Materials Co., Ltd., utilize two Aerospace Maiwei pulverized coal semi-waste boiler gasifiers to produce 100,000 m3/h of hydrogen and 200,000 tons per year of ammonia.
