On April 28, the dehydration tower for the EG unit in Donghua Technology’s Guangxi Huayi ethylene glycol plant was successfully hoisted into place. The dehydration tower weighs 48 tons, has a diameter of 2 meters and a height of 45.5 meters; after nearly a month of installation work, it has been successfully placed in position as planned. In accordance with the preliminary special plan titled \"Tower Erection and Lighting Activation\" developed by the project team, the plan requires that for the tower equipment covered by the heavy-lift operations, these devices must be properly prepared before lifting – in other words, the platform ladders, electrical lighting systems, instrument trays, pipelines used for climbing the tower, and the external insulation of the equipment must all be installed prior to lifting. The auxiliary facilities of the tower, which would normally need to be installed at high altitudes, are instead installed on the ground first, after which they are lifted and installed as a single unit, thereby ensuring that all pipelines are in place once the tower is erected and the lighting is activated. “The special planning scheme for \"Towers Built, Lights On\" addresses the issues of limited space at the construction site and the difficulty of storing equipment and materials. It also eliminates the costs associated with setting up scaffolding and other construction methods, thereby minimizing risks related to work at heights, concurrent operations, and the associated safety hazards. This improves construction efficiency and further accelerates the installation process.
