【Ten Years of Rapid Development in Chemical Equipment】2894–2025: SIC Heavy Industries Builds the World’s Largest and Heaviest EO Reactor

Thread Content

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 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 December 10th, the EO (ethylene oxide) reactors for the EO/EG units of the Sino-Saudi Ghulayyil ethylene project, which were manufactured by China National First Heavy Machinery Corporation, were shipped from the Dalian Nuclear Power and Petrochemical Equipment Manufacturing Base. This device has broken the world manufacturing record for the EO reactor with the largest diameter and greatest single-unit weight, further demonstrating China National Heavy Machinery Corporation’s technological innovation capabilities and expertise in high-end manufacturing as a key industrial entity of the country, as well as the significant value of Chinese manufacturing in major international cooperation projects. https://p3-sign.toutiaoimg.com/tos-cn-i-axegupay5k/775b5d95a6e44913952b43ac4576a178~tplv-tt-origin-web:gif.jpeg?_iz=58558&from=article.pc_detail&lk3s=953192f4&x-expires=1766042091&x-signature=MtXIc36CXf%2FOEfyy%2FW%2FWF4x4VXk%3D It is reported that the Zhongsha Gulei ethylene project represents a significant cooperation milestone between China and Saudi Arabia in the field of energy. It was built through a joint venture between Saudi Basic Industries Corporation and Fujian Energy & Petrochemical Group, with a total investment of 44.8 billion yuan. This project is a concrete example of the integration between the Belt and Road Initiative and Saudi Arabia’s “Vision 2030”. This project features good economic benefits, a large number of high-end products, low energy consumption and emissions, large-scale installations, and strong driving effects on downstream industries; it is of great significance for ensuring energy security as well as the stability of industrial and supply chains. “The ‘size’ of this equipment is significant in every aspect: its outer diameter is nearly 9.3 meters, its net weight per unit is 1540 tons, and it contains 32,437 heat exchange tubes inside. These parameters are the best among similar devices worldwide. ”Pak Myung-ho, the director of Dalian Nuclear Power and Petrochemical Equipment Manufacturing Plant, explained to the reporters. The reactor interior contains 10 layers of grills and 2 layers of tube sheets; to ensure that each heat exchange tube can pass through these 12 layers of obstacles smoothly, a very high level of assembly precision is required ； To complete the welding of over 60,000 heat exchange tubes and tube sheets to a high standard, not a single joint may be exposed, as this could pose safety risks and lead to cost losses. “The simultaneous successful delivery of these two reactors further demonstrates that China National Heavy Machinery Corporation’s technical and manufacturing capabilities in the field of tubular reactors are at the top level of the industry. ”
