【Ten Years of Rapid Development in Chemical Processing Equipment】The Two Largest Vessels with a Capacity of 3,000 Tons from 1981 to 2023

Thread Content

Looking at the ten-year development of chemical engineering technology, we praise the prosperity and strength of modern China. This is just a preliminary contribution; more participation from everyone will make things even more interesting. HAICHUAN becomes even better with you here. [Ten Years of Development in Chemical Engineering Equipment] – A continuously updated summary thread; feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html. Enhance quality awareness and promote high-quality development. ----------------------------------------- Settlers and regenerators, collectively referred to as the “two types of equipment,” are core components in catalytic units. Large size, heavy weight, complex structure, compact layout, long construction period. “The construction of the “two units” is a key milestone and a challenge in the building of catalytic cracking units. Recently, the first section of the regenerator and settler equipment for the 3.2 million tons per year catalytic cracking unit in the Daxie Petrochemical integrated project was successfully lifted, marking the transition of the catalytic unit at Daxie Petrochemical from the civil engineering phase to the equipment installation phase. It is reported that these two units, as the core equipment of catalytic cracking plants, have the largest scale in the country at present. The maximum diameter is 21 meters, the height of the equipment itself is 67 meters; after installation, the height can reach 78 meters. The weight required for its construction and lifting is nearly 3,000 tons. It is characterized by a complex structure, compact layout, and a long construction period. The regenerator to be lifted this time was manufactured in 6 sections; the first section is 14.5 meters high and weighs around 400 tons, and XCMG’s 4000-ton (1800-ton operating capacity) crawler crane was used for its lifting at the site.
