Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Development 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 July 1st, the core power equipment for the Sino-Saudi Ghulai Ethylene Project, located in the Ghulai Petrochemical Complex in Zhangzhou City, Fujian Province – namely the pyrolysis gas compressor developed independently in China – was successfully delivered and installed, marking the full entry of this project into the phase of installing mechanical equipment. The ethylene plant, with an annual production capacity of up to 1.8 million tons, serves as the core of the entire Zhongsha Gulei ethylene project; the pyrolysis gas compressor that has been installed this time is essentially the ‘heart’ of this core facility. The pyrolysis gas compressor is the engine that ensures the smooth circulation of \"high-temperature pyrolysis gas\" during the production process; it also serves as the key component for transporting the raw materials to the downstream separation systems. It is the \"lifeline\" and \"energy hub\" that enables the steady operation of the entire plant. The \"China Heart,\" with a total weight of over 600 tons, is composed of thousands of components, and its assembly precision reaches as high as 0.005 millimeters, which is one twentynd of the thickness of an A4 sheet of paper. Furthermore, the positioning accuracy of this equipment must reach 0.02 millimeters; such stringent requirements pose a significant challenge to the on-site lifting operations.
