The assembly accuracy of the agitator mounting port is also very high. The verticality tolerance between the agitator mounting flange and the cylinder axis is less than 0.0 1, and the coaxiality error between the agitator mounting flange and the cylinder axis is less than 2mm. Coaxiality error of upper and lower mounting flanges of agitator < <1mm.
The successful manufacture of such high-tech and super-large equipment depends on the strong technical force, high-quality and high-skilled production team and strict quality team of Daming Heavy Industry. The customer management team guided the whole process and made outstanding contributions to quality and schedule control.
The PE equipment hoisting of Liaoning Baolai light hydrocarbon comprehensive utilization project was successfully completed.
On August 1 day, 18, the last module (the fourth module) of the 107-meter-high degasser frame steel structure in the 450,000-ton/year LLDPE plant area of the light hydrocarbon comprehensive utilization project of Liaoning Baolai Chemical Co., Ltd. was successfully assembled, and the completion of the installation of the fourth module also marked the successful completion of the hoisting work of the whole PE plant area. From planning and deployment to assembly, hoisting and installation, the whole construction process witnessed the hard work of all managers and operators of Bora project department and construction team, and witnessed the tireless work spirit of thirteen builders in hot summer.
The overall weight of the steel structure of the degassing bin is 1 170 tons, the equipment of the degassing bin is 320 tons, the installation height of the steel structure is 32.6 meters-107 meters, the overall frame is designed as an ultra-high steel structure, and the steel columns are all welded cross steel, and the weight of a single main column reaches 27 tons. Therefore, the project department decided to prefabricate the steel structure in the factory and transport it to the construction site for assembly.
In the whole construction process, risk factors and operational risks are under control, and many difficulties and problems are encountered in the construction process, such as the installation of weighing modules, the ultra-high lifting height of equipment passing through steel frame, and the ultra-large frame size. Continuous rainy weather, material supply can not be timely and other constraints. In order to ensure the quality and progress, the project department makes timely deployment and coordination. In terms of operation, the whole team implements two shifts and 24-hour uninterrupted welding. In terms of technology, the project department organized many discussions and demonstrations in the form of special meetings to ensure the feasibility and safety of hoisting and installation. This series of efforts embodies the collective cohesion of the six companies and the spirit of Qi Xin's concerted efforts and common progress, ensuring the successful completion of the hoisting work of large PE devices.
Xinpu olefin
Xinpu olefin light hydrocarbon comprehensive utilization project will soon be put into trial operation.
According to the latest news, Taixing Xinpu olefin comprehensive utilization project with an annual output of165438+100000 tons of light hydrocarbons has entered a tense stage of unit commissioning and will be put into production in August, which indicates that Taixing Economic Development Zone will become the seventh "big ethylene" chemical park in China.
The project started construction in June, 2065438+2006 and took three years to complete. With a total investment of 5.5 billion yuan, it can produce 650,000 tons of ethylene, 6.5438+200,000 tons of propylene, 6.5438+450,000 tons of hydrogen, 45,000 tons of C4, 30,000 tons of methane and 45,000 tons of cracked gasoline. It is estimated that the annual sales revenue will increase by 654.38 billion yuan.
This is the first plant in China to produce ethylene by cracking ethane and propane. The ethylene yield is as high as 80.5%, far exceeding the 35% obtained from naphtha in the traditional process. In addition, the capacity of a single gas cracking furnace in this project is the largest in the world at present.
It is expected that enterprises in Taixing Economic Development Zone will realize self-sufficiency and get rid of dependence on imported ethylene raw materials, and extend downstream to PVC, polystyrene and other products. At the same time, it will promote the layout and level of the chemical industry in the park and even Taizhou, and help the rapid development of the regional economy.
Because the olefin project is known as "the largest olefin" and plays an important role in the industry, not only because ethylene is a resource product with strong industrial chain correlation in the chemical industry, but also because it has the characteristics of complex project equipment, high technology content and high investment intensity, the 165438+ 1 100 million tons light hydrocarbon comprehensive utilization project completed this time is rated as "extremely symbolic".
Wanhua chemistry
The particle mixing bin of 6353 device of Wanhua Chemical HDPE Project was successfully hoisted.
On July 23rd, the hoisting of the particle mixing bin of HDPE plant of Wanhua Chemical with an annual output of 350/300,000 tons of high-density polyethylene/polypropylene project, which was built by Sinochem Liu Jian Ningbo Branch, was successfully completed.
The lifting weight of the granular material mixing bin is 33 tons, the height is 3 1 m and the diameter is 8 meters. Because July is the key moment for all construction units to catch up with the construction period, and the site situation is complicated, it is necessary not only to overcome the problem of the transportation route of equipment entering the site, but also to choose the appropriate crane occupation point. Therefore, before the silo hoisting, the technicians, after accurate calculation and repeated argumentation, decided to adopt the hoisting scheme of 350-ton overhead truck crane and 80-ton crawler crane. At the same time, they communicate and coordinate with all units, plan transportation routes, arrange hoisting schemes, and strive to ensure smooth roads without affecting the normal construction of all construction units.
The aggregate homogenization frame has 14 silos, and the first batch is hoisted by two silos. The success of this hoisting marks the official start of the silo installation project of HDPE project.
With the timely completion of underground pipelines and steel structures, the installation of process pipelines of yantai wanhua Chemical Polyurethane Industrial Chain Integrated Ethylene Plant, which was built by the Tenth Construction Company, has started one after another.
The diameter of the process pipeline in this project is 6,543,800+0000 inches, of which the welding of special materials for ultra-high pressure steam pipeline is expected to reach 30,000 inches.
