Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, with the emergence of many new processes, products, and equipment. China’s chemical processing equipment has also seen significant progress, which in turn has contributed to the swift advancement of the petrochemical sector. Here, we have compiled some of the achievements and breakthroughs made by Chinese equipment manufacturers in terms of larger-scale production and greater use of domestic equipment. We invite everyone to share, discuss, and exchange ideas – let’s cheer for Made in China and support the development of chemical processing equipment! ========================== In September 2021, the polyester reactor equipment for Deshinib produced by Daming Heavy Industry’s Process Equipment Division was successfully manufactured and shipped to the project site. This project involves the polyester reactor equipment, which is the core component of the Xuanda PETL plant project and was undertaken by Technip Energies (one of the world’s largest engineering and technology companies). As an essential part of this project, the reactor design was carried out by Technip Zimmer in Germany, while DMG MORI’s Process Equipment Division was responsible for tasks such as the analysis and optimization of the design drawings, project procurement, manufacturing, testing, and shipment.
It is understood that the polyester reactor features a fish-scale-like jacket structure and internal heating coils; during operation, these jacket and heating coils are filled with a high-temperature heat transfer fluid (biphenyl) to keep the reactor at a high temperature. Before the polyester reactor leaves the factory, it is necessary to conduct actual operating condition simulations in strict accordance with the requirements, and carry out hot-state tests on the reactor to verify whether it can maintain a vacuum, as well as to check for any deformation of internal components such as the internal heating coils and to ensure there is no leakage of heat transfer fluid. Furthermore, due to the large size of this equipment, with an operating temperature as high as 330 degrees, and the fact that the equipment’s body must withstand external pressure thanks to the jacket, coupled with the complex structure of its internal coils, contamination by iron ions and other impurities is not allowed during the production process; hence, its production is extremely difficult. Upon receiving the order for this project, Daming Heavy Industry’s Process Equipment Division promptly established a dedicated project team. Starting with the selection of materials, the team members worked hard to overcome various challenges throughout the implementation process. In particular, they provided thorough support during the thermal testing phase – from inviting external experts to share their experience, to developing the testing platform, until finally completing the tests successfully and delivering them to the client.
Do you know where this project is?
The fact that core equipment such as reactors can be manufactured and exported by China is also a demonstration of its strength @RedLee_ZZHI @ZhizheMing @Li** @Jiuguan
