All equipment for the urea production unit in Hebei Zhengyuan’s hydrogen energy and clean, efficient comprehensive utilization of coal project has been accurately installed in place
Thread Content
Recently, all 115 units of the urea production facility in Hebei Zhengyuan Hydrogen Energy Technology Co., Ltd.’s project for the clean and efficient comprehensive utilization of coal were properly installed, marking the full entry of the project construction into its peak phase for pipeline installation. This project is a key project in Hebei Province, and it was constructed using the company’s own developed \"high-efficiency synthesis, low-energy consumption urea technology\". Upon completion of the project, it will produce 600 million Nm³ of hydrogen per year, with an annual production capacity of 300,000 tons of ammonia and 520,000 tons of urea. Once the project is put into operation, it will effectively drive the local coal chemical industry toward higher levels of sophistication, intelligence, and low carbon emissions, thereby injecting new momentum into the optimization of the energy structure in North China. To date, key tasks such as the successful initial lifting of the boiler drum and the precise positioning of the large tower assemblies have been completed ； 86.1% of the civil construction work has been completed; a total of 174 pieces of equipment have been installed, and the amount of pipeline welding has exceeded 53,386 dynes.

Recently, the ammonia synthesis tower (2R-3301), a piece of equipment for the Hebei Zhengyuan Hydrogen Energy and Clean, Efficient Comprehensive Utilization Project, was successfully hoisted into place. The construction of this project was carried out by the Beijing branch of China National Chemical Engineering Corporation Sixth Construction Co., Ltd. It is reported that the ammonia synthesis tower to be lifted this time is a veritable \"giant\" – standing 34 meters tall and with a diameter of 3 meters; its total weight is 683.69 tons, making it the heaviest piece of equipment in the Zhengyuan project. To complete this lifting task, the project team selected a 1,250-ton crawler crane as the main crane and an 800-ton crawler crane as the auxiliary crane. At the lifting site, the construction area is limited and the equipment is heavy, posing significant challenges to the operations.
Recently, the Hebei Zhengyuan Hydrogen and Coal Comprehensive Utilization Project Department successfully completed the relocation and lifting of its first large-scale equipment: a 1,000 m3 liquid ammonia sphere tank. The liquid ammonia sphere tank has a height of 15 m, a diameter of 12 m, a weight of 230 t, and a volume of 1,000 m3. The mechanical subsidiary company responsible for carrying out this lifting operation used a Zoomlion 650 t crawler crane, with a 420 t counterweight for lifting. Before the lifting operation, the project department developed a detailed lifting plan, ensuring proper coordination of details such as the lifting methods, lifting equipment, foundation treatment, emergency response plans, and safety measures. This approach reduced the risks associated with the lifting process and ensured its smooth execution. With close cooperation from all team members, it took a little over 2 hours to safely lift the liquid ammonia sphere tank to the designated location, thus completing this lifting operation successfully. The project department stated that it will continue to strengthen management in order to complete the project construction with high standards and high quality.
