CNPC News released on August 30 said that CNPC has mastered the development and design of large-scale ethylene cracking furnaces with independent intellectual property rights. CNPC's Science and Technology Management Department organized a major science and technology special large-scale ethylene plant industrialization complete set of large-scale cracking furnace technology package review meeting. The large-scale cracking furnace technology package prepared by China Ryukyu Engineering Company passed the expert review.

The review panel believes that the content of the technological package is relatively comprehensive and the depth is in line with the requirements of the “Content Regulations of the Process Design Package for Petrochemical Devices†and can be used as the basis for the preliminary design compilation. The successful development of a large-scale ethylene pyrolysis furnace process package not only lays a solid technical foundation for the successful commissioning of Daqing Petrochemical's 1.2 million-ton/year ethylene renovation and expansion project, but also makes important contributions to the further improvement of China's ethylene industry's independent technological level and localization rate. .
Ethylene plants are hailed as the "leading" in the petrochemical industry. Scale and production capacity are the hallmarks of a country's petrochemical industry. Cracking furnaces are the core equipment of large-scale ethylene plants. Over the years, China's new large-scale ethylene plant cracker technology package has been relied on from the introduction of foreign companies, the cost remains high. After many expert scientific demonstrations, CNPC decided to set up a major science and technology project for large-scale ethylene plant industrialization and development of complete sets of technology. Relying on Daqing Petrochemical's 1.2 million-ton/year ethylene renovation and expansion project, it will be developed and formed through the introduction of digestion, absorption, and innovation. With independent intellectual property rights, it has reached the world's advanced level of large-scale ethylene complete sets of industrial technology.
During the implementation of the project, China Ryukyu Engineering Co., Ltd., the leading unit of this major scientific and technological project, learned from the experience of many domestic ethylene cracker engineering designs and the operational experience of production companies, and conducted the key parts of Daqing Petrochemical's ethylene cracking furnace. Detailed structural design and stress analysis and calculation, through the integration of innovation and independent innovation, developed a large-scale ethylene cracker technology package with independent intellectual property rights. The large-scale ethylene pyrolysis furnace developed by China Ryukyu Engineering Co., Ltd. has a reasonable technological process, controllable technical risks, and technical and economic indicators such as olefin yield have reached the domestic leading level; furnace tubes, new spiral plate air preheaters and cracked gas in the radiant section of the pyrolysis furnace Quenching heat exchangers and other aspects have strong innovation.
