On July 21, the country’s largest gas cracking furnace with a capacity of 200,000 tons per year completed its performance evaluation. This gas cracking furnace, which possesses entirely independent intellectual property rights owned by Sinopec, has been operating smoothly at Zhenhai Refining & Chemical Complex for 30 days. This marks another improvement in the quality of China’s independent innovation capabilities in the field of large-scale ethylene production, adding further weight to China’s reputation as a leader in refining technologies. 　　The cracking furnace is the key facility and core equipment for producing ethylene. The commissioning of Zhenhai Refining & Chemical’s 200,000 tons per year gas cracking unit has not only increased the production capacity of the ethylene plant by 10%, but it has also provided greater opportunities for optimizing raw materials and more flexible methods, thereby raising the overall competitiveness of ethylene production to a new level. 　　The gas pyrolysis furnace utilizes Sinopec’s own CBL pyrolysis technology, and features four innovative advantages: the largest scale, the ability to handle both gas and liquid materials, a dual-chamber design, and environmentally friendly technology. 　　The design, manufacturing, and construction of the 200,000 tons per year gas cracking furnace were all carried out domestically; it was designed and constructed by Sinopec Refining & Chemical Engineering Company (SEG), highlighting the competitive advantages of China’s refining and chemical technology. As the owner, Zhenhai Refining & Chemical, along with the research, design, construction, and supervision units, work together in unity to strive to create high-quality and exemplary projects. It took only 25 months from pile driving to completion by CCCC, and only 5 months from the start of furnace heating to the commencement of operation. 　　Currently, the operation of this furnace remains stable; the proportion of naphtha has further decreased, the raw materials are lighter in composition, and the yield of high-value-added products has increased.
