Let’s give praise and support to the achievements made in China’s chemical engineering technology and equipment. Your participation in discussions is the greatest encouragement. **********************【Ten Years of Progress in Chemical Engineering Equipment】Regular updates and summaries are available; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On October 1st, as various units of Guangxi’s petrochemical integration and transformation project began operations one after another, the high-performance anti-corrosion coatings developed by CNPC Offshore Technology Research Company were also put into use in this project, marking another successful application of this company’s research results regarding anti-corrosion coatings for the long-term safe operation of petrochemical plants and related facilities. This represents yet another confirmation of the effectiveness of these coatings in supporting the construction of petroleum refining projects.   The Guangxi Petrochemical Integration and Upgrading Project is located in Qinzhou, Guangxi, along the coast. It is exposed to high temperatures, high salinity, and high humidity throughout the year, with intense ultraviolet radiation; as a result, the corrosion rate of steel is 4 to 5 times higher than in inland areas, which poses extremely high demands on anti-corrosion technologies. China National Offshore Oil Engineering Technology Research Company focused on the technical requirements of various projects, formed teams dedicated to developing innovative solutions, and successfully created a range of products and construction methods, including high-temperature and corrosion-resistant coating systems suitable for temperatures ranging from 200 to 700 degrees Celsius, long-lasting weather-resistant anti-corrosion coatings, as well as anti-corrosion coatings that require minimal surface treatment. These coatings are widely used in equipment and containers such as those for ethylene cracking in Guangxi’s petrochemical industries, as well as in process pipelines and steel structures, demonstrating excellent protective properties. This coating system exhibits excellent resistance to salt spray corrosion and weathering; the coating can withstand salt spray exposure for over 2000 hours, and it also resists artificial climate aging for more than 2000 hours, making it suitable for CX-grade extreme corrosive environments.   At present, China’s refining, chemical processing, and new materials industries are in a crucial phase of transformation and upgrading. Enterprises are actively advancing the construction of integrated refining and chemical processing facilities, and the demand for high-end, functional anti-corrosion coatings continues to rise. The head of the anti-corrosion technology team at CNPC Offshore Engineering Technology Research Company explained that, in light of the corrosion characteristics and functional requirements of different parts of refining and petrochemical facilities in marine atmospheric environments, the R&D team conducted over 600 laboratory tests and more than 80 field trials, developing a series of anti-corrosion and protective coatings with special functions. They have also continued to work on optimizing these systems and improving the formulation techniques used. At present, an anti-corrosion coating system for refining and chemical processing facilities has been developed, covering 16 types of specialized technical products. This system can meet the standards-based construction requirements of large-scale refining and chemical enterprises, providing long-term protection of over 8 years; the total amount applied so far has exceeded 2,000 tons.   As a professional technical service provider in the field of anti-corrosion for the petroleum and petrochemical industries, CNPC Offshore Technology Research Company has provided technical support for projects such as Dalian Petrochemical and Dagang Petrochemical for over 20 years. At present, these anti-corrosion technology products in this series are being applied in various major projects such as the Blue Ocean New Materials high-end polyolefin project and the Dushanzi Petrochemical Tarim Phase II ethylene project, and have achieved good results in large-scale integrated refining and chemical projects such as Jilin Petrochemical and Guangdong Petrochemical. The company has had 5 scientific and technological achievements recognized as key products resulting from independent innovation by the group company; it has played a leading role in drafting 13 industry standards in the field of corrosion prevention, and has received 10 awards for scientific and technological progress from the group company. It continues to leverage technology to promote the high-quality development of China’s petrochemical industry.
