Thread Content
Red May for chemical industry workers! Reply reward! ---------------------------------------------- The past decade has been a period of rapid development for China’s chemical industry, marked by the emergence of many new processes, products, and equipment. There has also been significant progress in China’s chemical processing equipment, which 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 their insights and discuss these topics together; let’s cheer for Made in China and support the development of chemical processing equipment! =====================
On May 11, the DCS control system renovation project for the aromatics complex at Sinopec Yangzi Petrochemical, with a total investment of 45 million yuan, was completed. This renovation not only improved the intrinsic safety level of the aromatic compounds complex but also created the conditions for the development of a smart factory at Yangzi Petrochemical. The aromatic compounds complex uses a foreign-made DCS control system; it has been in operation for over 20 years. The system is aging, suffers from high failure rates, and lacks stability and reliability. There are equipment defects and safety hazards, making it difficult to meet the requirements for optimal operation of the complex even after multiple renovations. Additionally, aspects such as communication, intelligent instrument control management, and network structure security fail to meet the standards required for intelligent control. In 2018, the DCS control system renovation project for the aromatic compounds complex was listed as a key upgrade project for Yangzi Petrochemical, and the renovation officially commenced in October 2021. This upgrade involves replacing the entire original system with the domestic Zhejiang Zhongkong ECS-700 system. In March this year, the aromatic compounds complex was shut down for maintenance, and the construction work entered its final phase. Yanzhi Petrochemical, Sinopec Nanjing Engineering Company, Yanzhi Supervision Company and other participating units worked together in close cooperation. After 8 months of hard effort, successful power supply to the new system was achieved on April 26, ensuring that the project was completed to high quality and standards.
I’m a bit confused. The renovation started in October 2021 and was completed on April 26 – so that’s 8 months?
The renovation officially began in October 2021. 10=11=12=1=2=3=4=5
10-11, 11-12, 12-1, 1-2, 2-3, 3-4.26 – shouldn’t it be calculated this way?
For example, it starts on October 20th and ends on November 20th. Isn’t that just a month of hard work? If it’s for two months, well… the contractor was happy, hahaha
