This represents another significant milestone in the project, following the successful installation of the air-cooling towers and water-cooling towers on November 1, as well as the completion of the construction of the main cooling box on November 3. The main equipment for the project’s air separation pre-cooling system and purification system consists of 4 units. Among them, the air-cooled tower and the water-cooled tower, which were successfully installed on November 1, are part of the air separation pre-cooling system. The water-cooled tower has a diameter of 4 meters, a height of 26 meters, and a weight of 36.48 tons, while the air-cooled tower has a diameter of 4.2 meters, a height of 25.7 meters, and a weight of 56 tons ； The two molecular sieve adsorbers are part of the purification system; they have a diameter of 4.2 meters and a length of 19 meters, with each one weighing 59 tons. The Zhejiang Jinju air separation project is a new construction and renovation project for the old plant site of Zhejiang Jinju Chemical Co., Ltd.
