Recently, news from Maoming Petrochemical's 1-million-ton/year ethylene renovation and expansion project construction management department reported that the total investment was 7.49 billion yuan, and China's first million-million-ton ethylene project was put into operation immediately, and the localization rate of equipment reached more than 60%. . Relevant experts believe that this will play a role in demonstration and reference for localization of large-scale ethylene equipment.
The project uses a 100,000-ton/year ethylene cracker jointly developed by Sinopec and Lummus Corporation of the United States; 2 sets of 46-meter polypropylene loop reactors and various towers developed by Maoming Gravity Petrochemical Equipment Co., Ltd. Special valves, etc.; The heart of its ethylene cracking equipment --- 600,000-ton ethylene cracker compressor developed by the Shenyang Blower Group successfully, after the trial run performance is good, is currently China's own development of the largest power of such compressors; The largest ethylene cold box manufactured by the Hangzhou Oxygen Concentrator Group has a maximum design pressure of 3.96 MPa and is currently the world's largest ethylene cold box produced using a three-way refrigeration process. In addition, a series of domestically developed petrochemical equipment such as high-efficiency heat exchangers and cryogenic pumps have also been adopted in the Maoming Ethylene Expansion and Expansion Project.
According to Wang Tingjun, the original director of the China National Petroleum Corporation's major equipment localization office, after more than ten years of research and development, the domestic production rate of 300,000 tons/year of ethylene engineering equipment in China has reached more than 70%, but a large-scale equipment development capability has not yet formed a system. . The Maoming one-million-ton ethylene renovation and expansion project has an equipment scale of 600,000 tons per year, which is a transitional attempt for the construction of a million-ton ethylene project in the future. It will play a role in the localization of large-scale ethylene equipment. Valuable demonstration and reference.
It is understood that since last year, China has successively developed and manufactured millions of tons of large-scale ethylene complete sets of equipment with four sets of million-ton ethylene projects in Tianjin, Zhenhai, Fushun and Chengdu as its domestically-relied projects. According to the deployment plan of the National Development and Reform Commission, the localization rate of Chengdu million-ton ethylene engineering equipment will reach 85%, 4 sets of 12 sets will fully use domestic technology, and 3 sets of domestic and foreign technology selection will be preferred. The rest of the devices use foreign technology, of which the ethylene device only introduces technology packages.
