At 12:48 on March 31, 2022, at the construction site of Shaanxi’s 400,000-ton coal-based ethylene glycol project, the tallest tower in the ethylene glycol production facility – the ethylene glycol distillation T4 B tower – was successfully installed in place! The ethylene glycol distillation T4 tower is the tallest tower in the company and a key piece of equipment in the ethylene glycol distillation system; there are two such towers, labeled A and B. Tower T4 B was lifted in two sections, the lower section having been installed on March 21. The current lifting operation involved raising the upper section of Tower T4 B, with construction workers successfully joining the upper and lower sections in mid-air at a height of 50 meters. The successful completion of this lifting and alignment process marks the full entry of the ethylene glycol plant for the company’s ethylene glycol project into the fast track of equipment installation. It is reported that the ethylene glycol distillation T4 towers were manufactured by Xi’an Nuclear Equipment Co., Ltd.; there are two such towers, labeled A and B, both with dimensions of φ5100*87910 mm and a weight of 427 tons each. For this lifting operation, a 1,250-ton crawler crane was used as the main crane, and a 260-ton crawler crane was used as the auxiliary crane.
