China's first 150,000-ton/year ethylene cracker, Zhenhai Refinery's ethylene cracker No. 11 cracker, began receiving naphtha on July 27, and officially began operation, marking a major breakthrough in China's ethylene production technology. This cracking furnace has the advantages of high annual production capacity, low investment, and low energy consumption. Moreover, due to the adoption of the double furnace structure, split furnace cracking and split furnace burning can be realized, and the operation is relatively flexible. At the same time, the furnace has a dual radiation section and a single convection section structure, and the furnace tube is a highly selective 2-1 type two-way tube with excellent performance.
