SPCECC 3200t crawler crane successfully completed the lifting task
- SPCECC contributes to the development of Fujian Zhongjing Petrochemical
- SPCECC will fully carry forward the spirit of chemical construction railway army, and comprehensively create high-quality projects and reassuring projects
Hold your head high, and the pagoda will soar to the sky. On November 21, 2022, in Fujian Fuqing Jiangyin Zhongjing Petrochemical Science and Technology Park, the hoisting ceremony of the propane propylene separation tower with the highest height and largest volume in the world for the Zhongjing Petrochemical 1 million tons of propane dehydrogenation (Phase II) project contracted by SPCECC was launched. Li Keshe, Deputy Secretary of the Party Committee and General Manager of the Company, was invited to attend and speak.
At the hoisting ceremony, Li Keshe said that SPCECC successfully completed the hoisting of the propane propylene separation tower with a height of 138 meters and a weight of 2700 tons by using the company's own 3200 ton crawler crane, which can be disassembled into a 1600 ton model in the world, marking that the project construction has entered the "fast track" of installation. SPCECC will adhere to the corporate purpose of "survival with quality, development with reputation", and fully carry forward the spirit of "iron army" of chemical construction, As always, we will strengthen the management of safe and civilized construction, comprehensively create high-quality projects and reassuring projects, ensure that the project is completed and put into operation on schedule with guaranteed quality, and contribute SPCECC to the development of Fujian Zhongjing Petrochemical.
The propane propylene separation tower hoisted this time is the core equipment of Zhongjing Petrochemical's 1 million ton/year propane dehydrogenation project, and it is also the highest and largest propane propylene separation tower in the world, with a height of 138 meters, a weight of 2700 tons, and a volume of 11000 cubic meters. Combined with the actual situation on site, SPCECC is installed by means of on-site assembly and sectional hoisting.
On November 20, the head of propane propylene separation tower was ready for hoisting, and the "last hoisting" of the tower was welcomed. As the hoisting height reached 138 meters, the high altitude strong wind hindered the hoisting, assembly, welding and other work, which became the biggest difficulty of the hoisting operation. In order to ensure the successful completion of hoisting, the project hoisting team adopted the methods of adjusting the length of hoisting wire rope to ensure the levelness of the head, chain block to fix the attached tower pipeline, and installation of temporary platform to ensure the smooth hoisting of the head. At 7:00 a.m., with the help of 3200 ton crawler crane, the separation tower head was lifted steadily under the leadership of the hoisting commander in chief; At 8:20, the head and body of the separation tower completed a beautiful "combination" at a height of 100 meters, marking the successful completion of the lifting of the propane propylene separation tower with the highest height and largest volume in the world, and again demonstrating SPCECC's "hard power" with practical actions.
It is reported that Zhongjing Petrochemical's propane dehydrogenation project with an annual output of 1 million tons has a total investment of 4 billion yuan and an annual output value of 10 billion yuan, which can drive the output value of upstream and downstream industrial chains of 20 billion yuan. The project introduces the most advanced propane dehydrogenation to propylene production process technology of Loomis, which represents the world today, to produce high-purity propylene raw materials to meet the needs of downstream copolymerized polypropylene in the park. In the process of technology introduction, engineering design, construction and installation, the project overcame many difficulties and realized the first localization of 50 MW positive pressure explosion-proof motor and 169 MW air heater.
In recent years, with the demand for large-scale, large-scale and modular construction of petrochemical industry devices, the advantages of large equipment ground assembly and overall hoisting are highlighted. SPCECC, which mainly undertakes petrochemical engineering construction, undertakes more and more large-scale construction tasks, and has undertaken project construction in Iran, Bangladesh, Malaysia, Nigeria, Russia and other countries abroad. In order to further meet the construction needs and improve the market competitiveness of the enterprise, SPCECC has purchased 3200 tons, 1600 tons, 800 tons, 600 tons, 450 tons and other hoisting equipment of different tonnage levels. At present, Shaanxi Chemical Construction Machinery Co., Ltd. has a strong strength, with more than 5900 sets of various construction machinery and equipment, which can simultaneously meet the construction tasks of dozens of large-scale petroleum, chemical and energy projects, and successfully completed more than 1200 key projects at home and abroad, In particular, the hoisting capacity of large equipment has leapt to the forefront of the domestic petrochemical construction industry, and has been ranked among the "top ten hoisting enterprises in China" for 11 consecutive years.
