On the morning of August 16, the installation of the sixth section of the product separation tower for the 600,000-ton/year propane dehydrogenation unit in Ningbo Jinfafa’s 1.2 million tons/year polypropylene thermoplastic elastomer and modified materials integrated project was completed successfully, marking the completion of the installation of all the major tower equipment for this 600,000-ton/year propane dehydrogenation unit. This lays the foundation for the project to enter the phase of installing process equipment. The product separation tower is the core equipment of the propane dehydrogenation unit; it is assembled in six sections, with a diameter of 9.2 meters, a height of 128 meters, and a total weight of 2,850 tons. Construction tasks such as equipment lifting, aerial assembly, installation of accessories, and pre-installation of internal components are among the most challenging in similar installations. The construction period for the product separation tower – ranging from the pile foundation to subsequent pressure testing of the tower body, as well as the installation of pipelines and trays attached to the tower – accounts for two-thirds of the total construction time for the entire facility. Effective planning of the on-site construction area, proper allocation of human resources and equipment, and management of HSE-related risks are all of paramount importance. During the hoisting construction of the product separation tower, the relevant departments of the company, together with the construction contractor and supervision unit, overcame difficulties such as the pandemic, extreme heat, and the transportation of large-scale equipment to ensure the smooth progress of the project. Scientific and rational construction organization management, along with close coordination among various specialized processes, provided strong support for the work on this critical path.
On April 15, the second section of the product separation tower for the 600,000 tons per year PDH unit in the Ningbo Jinfafa Integrated New Materials project, which is being constructed by the Fifth Branch of Sinochem Sixth Construction Company, was successfully lifted into place. The project is located in the Qingzhi Chemical Industry Park in Beilun District, Ningbo City, Zhejiang Province. It falls under the green petrochemical industry framework of Ningbo’s \"246\" initiative for developing trillion-yuan-level industrial clusters, and it is also one of the 9 industrial cluster projects in Ningbo worth 10 billion yuan each as of 2021. Once completed, the project will establish Jinfa Technology’s full industrial chain for \"propane–propylene–polypropylene–modified new materials\", playing an important role in industries such as home appliances, automobiles, and medical devices. Sinochem Sixth Construction mainly undertakes the construction work related to a new 600,000 tons per year propane dehydrogenation plant, including civil engineering, equipment installation, pipeline installation, electrical work, and instrument installation. The separation tower of this unit has a total height of 128 meters, and its own weight is approximately 1,790 tons; it constitutes a super-large-scale piece of equipment. The second section of the separation tower to be lifted this time weighs 450 tons, with a lifting height of 60 meters and an operating radius of 100 meters. The project team carried out all necessary preparatory work in advance, overcame the impact of adverse factors, and ensured the successful lifting of the second section of the separation tower.
On March 12, under a clear sky and with warm spring weather, a cool sea breeze blew over all the things that were coming back to life. At the site of Project II for the propane dehydrogenation unit of Ningbo Jinfafa New Materials Co., Ltd.’s integrated project for producing 1.2 million tons per year of polypropylene thermoplastic elastomer (PTPE) and modified new materials, in the Qingzhi Chemical Industrial Park in Beilun, Ningbo, the installation work for the first section of the 5300 separation tower was in full swing. At 1:18 p.m., the lifting of the equipment in the first section of the 5300 separation tower officially began. The item to be lifted this time was the first section of the separation tower, with a total height of 128 meters and a weight of 397 tons. Amidst the roaring sounds of the 900-ton main crane and the 500-ton auxiliary crane, the equipment was slowly raised from the transport vehicle and safely lowered right above its foundation. With the assistance of the installation crew, at 3:06, the first section was accurately installed on its foundation. The lifting of the 5300 separation tower equipment this time serves as a milestone for this project, marking the transition of the propane dehydrogenation unit from the civil construction phase to the installation phase after 8 months, starting from August 2021.
