This marked that the cracking furnace of the ethylene unit of the Tarim 1.2 million tons/year second phase ethylene project entered the installation stage of convection modules, furnace tubes, etc. Tarim's 1.2 million tons/year second phase ethylene and supporting green low-carbon demonstration project is a concrete manifestation of important decisions and arrangements for promoting the supply-side structural reform and high-quality development of the petrochemical industry. Under the background of the "Belt and Road" construction, relying on unique location advantages, the advantages of "low cost, large scale, short process, and low investment" of ethylene downstream products are used to maximize the value of resource advantages. As the "leading" device of the entire site, the ethylene plant has a total of 7 cracking furnaces, including 2 gas furnaces and 5 liquid furnaces. Each cracking furnace is composed of 2 radiation chambers. The cracking furnace manufacturing adopts the construction mode of modular prefabrication and overall hoisting. dd shortens the manufacturing and installation cycle and leads the project with "six modernizations" practice. For this cracking furnace construction, the project department collaborated with the team of Huanqiu Beijing Company to give full play to the advantages of integration and consortium, anchoring the three major construction goals of "demonstration project, high-quality project, and benchmark project", and taking "factory prefabrication and modular installation" as the core The main line is to focus on party building closely around on-site construction and production, strengthen the embedded integration of party building, give full play to the leading role of party building, vigorously explore new ideas, new measures and new methods to promote "Party Building + On-site", combine the installation of cracking furnaces and large tower equipment hoisting, full-site management, and road construction to stimulate the endogenous force of party building. Party members and cadres give full play to the role of model leaders, rush to the front, work in the forefront, and practice it with practical actions * * members’ responsibilities and responsibilities. Comprehensively promote the "six modernizations", work hard on management innovation and work efficiency improvement, give full play to the advantages of "modular installation", innovate the construction process, and complete the welding of anchor nails and pull brick plates inside the furnace in one flat welding at the prefabrication site. The welding meat is full and smooth, and the welding is well formed in one go. The cycle is shortened by 2/3 compared with the previous welding method, ensuring high standards of construction quality and effectively reducing safety risks. At the same time, the prefabricated depth of factory column footings, stiffeners, and connecting beams is realized, and the error between the foundation axis spacing and the body column axis spacing is strictly controlled to achieve precise placement of the cracking furnace radiation chamber. At the same time, the company aims to "lead the way by example and strive for high-quality projects". Gan Shengjiang, the company's deputy general manager and chief engineer, provides on-site guidance and strictly follows the owner's on-site construction requirements and organizes implementation with high standards and high quality. Through continuous optimization of the construction organization plan, design, procurement and construction are "seamlessly connected", fully tapping the potential of internal resources, improving collaborative operations capabilities, realizing resource integration, greatly improving management efficiency, and striving to build the project into a green and low-carbon demonstration project. Before hoisting, the project department combined the successful experience of previous on-site hoisting, organized personnel to conduct risk inspections in the hoisting area, conducted safety technical briefings for on-site hoisting workers, crane drivers and other special operations personnel, and explained in detail various problems and solutions that may arise during the hoisting process. At the same time, the hoisting process and safety precautions were emphasized. The hoisting plan was continuously optimized, and the hoisting efficiency was accelerated. The successful completion of this hoisting operation is a concentrated demonstration of the sincere cooperation, scientific scheduling and superb construction technology of the project team. The radiation chamber is the "heart" of the cracking furnace. The success of this installation means an important step forward for the smooth construction of the project.
