According to Sinopec News Network (Duan Peng), on the morning of March 6, the high-pressure amine absorption tower for the wax oil hydrogenation unit in Hengli (Dalian) Petrochemical’s 20 million tons per year integrated refining and chemical processing project, which was constructed by the 10th Construction Company for Refining and Chemical Engineering projects, was successfully installed. This marks the entry of this project into the equipment installation phase. It is understood that the high-pressure amine absorption tower weighs 572 tons, has a diameter of 3.6 meters, and an installation height of 29 meters. For this lifting operation, a 1,600-ton crawler crane was used as the main crane, with a 400-ton crawler crane serving as an auxiliary crane. The project team overcame various challenges such as the late arrival of the lifting equipment, limited time for preparation of the lifting operations, as well as severe wind and cold conditions. Before the lifting operation, the relevant departments provided the workers with detailed safety and technical instructions, implemented safety precautions, to ensure that the lifting process was carried out safely and securely. The high-pressure amine absorption tower is a framed equipment unit, and it is delivered with the trays removed, which results in the equipment being only 50 cm above the ground. To ensure the smooth installation of the safety platform at the top of the tower, the project team came up with a solution: while maintaining the safety of the equipment, they dug a pit at the location where the safety platform would be installed, thereby creating space for its installation. At present, the large-scale equipment for the two wax oil hydrogenation units in Hengli (Dalian) Petrochemical’s 20 million tons per year integrated project is being delivered one after another, and the construction of the entire project is now on fast track. The project management team for Hengli’s project in Dalian continues to work hard on management innovation and improving work efficiency, building on the existing innovative achievements. By addressing the weaknesses in project execution, it aims to ensure safe, high-quality, and efficient progress in the project’s construction, thereby turning Hengli (Dalian) Petrochemical’s project into a model project of excellence.
