Safety first. Prevention first: Let’s praise and encourage the achievements made in China’s chemical technology and equipment industry. **********************【A decade of significant development in chemical equipment】Continuous updates and summaries are available; feel free to join the discussions at https://bbs.hcbbs.com/thread-3576046-1-1.html (Source: Haichuan Chemical Forum Website) *****************In October 2024, the dehydration tower for the acetic acid production unit of the Juzhengyuan (Jieyang) Acetic Acid Project – the world’s largest single-unit acetic acid production facility – was successfully installed, marking another important milestone that has been achieved. It is understood that the Juzhengyuan (Jieyang) acetic acid project is a key project under Guangdong Province’s “Hundred-Thousand-Million Project”. The main components of this project include an acetic acid production facility with an annual capacity of 1.5 million tons, CO deep cryogenic separation and compression units, as well as various supporting utilities and auxiliary facilities. Once completed, the project will fill the gap in acetic acid production capacity in Guangdong Province, laying a solid foundation for the further development of the downstream acetic acid industry chain. The dehydration tower that was lifted this time is one of the core equipment in the acetic acid plant; it weighs around 131 tons and is approximately 49 meters tall. Its main structure is made of zirconium, and due to the complexity of welding this material as well as the strict requirements regarding the working environment, the lifting operation required great urgency and effort. The project team used a Zoomlion 800-ton crawler crane as the main crane and a 260-ton crawler crane as the auxiliary crane; the two cranes worked together to smoothly transfer the equipment in from the side of the acetic acid frame. The entire process was smooth and efficient, and the equipment was successfully installed at around 10 a.m. on October 6th.
