On March 14, 2025, the last convection section module of the ethylene unit cracking furnace of the Tarim Phase II Ethylene Project of Dushanzi Petrochemical Company was installed 15 days ahead of schedule, which won valuable time for the smooth advancement of the project and also marked the important phased results of the construction of the Tarim Phase II Ethylene Project. There are 7 cracking furnaces with a total of 49 convection section modules. The Tarim Phase II Ethylene Project Department of CNPC Sixth Construction takes "factory prefabrication and modular installation" as the main line, giving full play to the advantages of "modular installation." During the hoisting process, the hoisting of each module must be foolproof. Every lifting, moving, and positioning requires precise and error-free operations. The cracking furnace convection section modules appear to have the same appearance, but in fact there is a certain deviation in body weight and height. When we install each module, we will conduct on-site confirmation in advance, and ultimately complete the installation tasks of all modules efficiently. The convection section module of the ethylene unit cracking furnace of the Tarim Phase II Ethylene Project was installed 15 days ahead of schedule, creating favorable conditions for subsequent steel structure installation and greatly boosting the morale of all project builders. 2025 is the "installation year" and "production preparation year" of the Tarim Phase II ethylene project. The time is tight and the tasks are heavy. All participants are working hard to promote the project construction.
On March 14, as the convection section modules M4~M7 of the 7# cracking furnace were hoisted one after another in one day, all 49 convection section modules of the ethylene unit cracking furnace of the Tarim 1.2 million tons/year second phase ethylene project of Global Beijing Company were installed in place. The completion of this milestone node is 3 months ahead of the third-level plan, creating favorable conditions for the subsequent process pipeline construction and ancillary equipment installation of the cracking furnace. The first module of furnace 4 was hoisted on December 31, 2024. By January 20, 2025, it took 21 days to complete the hoisting of 28 modules. ； After resuming work during the Spring Festival, the first module of furnace 2 was hoisted on February 28, 2025. By March 14, it took 15 days to hoist 21 modules. It took a total of 36 days to hoist the 49 modules, with a total hoisting weight of 6,829 tons.
During this process, the project team worked together, organized precisely, and coordinated various EPC tasks, carried out in-depth "factory prefabrication and modular construction", strengthened quality control throughout the entire process, and created a "six modernization" practice-leading project. On the premise of meeting the process requirements, the design team comprehensively considered transportation, hoisting and other factors to carry out maximum modular design. At the same time, we strengthen communication with manufacturing plants and promptly solve design problems encountered during manufacturing. Relevant majors worked together to complete the release of design drawings ahead of schedule, creating conditions for manufacturing and construction. The procurement team planned in advance, reasonably subcontracted according to the specifications and quantity of the furnace, and successfully completed the contract signing, laying the foundation for the early delivery of the convection section. Establish a tracking mechanism for imported furnace pipes of key materials to monitor the supplier's procurement progress in real time. Additional expediting engineers will be deployed at the factory, and a daily reporting system will be adopted. Once delays are discovered, the production rhythm will be adjusted in a timely manner, and suppliers will be coordinated to increase space, manpower and other related resources to ensure that modules are shipped as scheduled. Faced with the overweight of the convection section of this project and the transportation distance of more than 4,300 kilometers, we participated in the supplier's transportation planning in advance, reported the location of the modules in a timely manner, and efficiently linked with the construction site.
The construction of the cracking furnace of the Tarim Phase II Ethylene Project has entered the installation stage of the quenching heat exchanger of the accessory equipment https://bbs.hcbbs.com/thread-5682227-1-1.html (Source: Haichuan Chemical Forum)
