In the coming period, China will vigorously develop an ethylene project with a scale of 800,000 to 1 million tons. By 2010, China will need to add about 8 sets of 800,000 to 1 million tons of ethylene complete sets of equipment. By 2020, additional sets of equipment will need to be added. 9 sets.
Therefore, during the "11th Five-Year Plan" period, there will be a market demand of large-scale ethylene equipment of about 56 billion yuan, and there will be a market demand of equipment of 63 billion yuan during the "12th Five-Year Plan" period.
At the end of August this year, Zhang Guobao, deputy director of the National Development and Reform Commission, pointed out in analyzing the crux of the localization of major technical equipment: "In recent years, China's equipment manufacturing enterprises have cooperated with user companies, and have absorbed, re-innovated, and independently developed key technologies for the introduction of large-scale petrochemicals. New breakthroughs have been made in the localization of equipment.†At this time, the operation of the Shenyang Blower Works in 2005 for Maoming Petrochemical’s 800,000-ton/year ethylene plant with a stand-alone capacity of 640,000 tons/year of cracking gas compressors shows that the unit performance has reached The international advanced level is currently the largest cracking gas compressor in China. Shengu developed a single machine capacity of 640,000 tons / year cracking gas compressor end of the million-ton ethylene cracking gas compressor must rely on imported passive situation, for our country in the world of large gas compressor manufacturing sector to win the right to speak.
Development Status of Ethylene Plant Core Equipment First of all, the research and development of the cracking equipment of China's petrochemical equipment has made progress (see one of the relevant links for details). Wang Tingjun, former director and professor-level engineer of the Sinopec's Major Equipment Localization Office, said that under the joint efforts of design, research, manufacturing, and users, China has successfully developed a new type of cracking furnace with Chinese characteristics. At present, Sinopec Group is in technical cooperation with Lummus of the United States to produce 100,000 to 120,000 tons of large-scale cracking furnaces for the preparation of a one-million-ton large-scale ethylene project (see relevant link 2). The upcoming Yanhua ethylene project will be transformed from 450,000 tons to 660,000 tons. The large-scale ethylene cracking technology jointly developed by Sinopec Technology Development Center and Lums will be used for the first time.
Second, large-scale ethylene spherical tanks are fully domesticated. Large-sized ethylene spherical tanks are restricted by materials and process technologies because they are used at a low temperature of -30 degrees Celsius. In the early days, large-scale ethylene ball tanks in China have not been domesticated, and all are imported from abroad. During the "Eighth Five-Year Plan" period, the CF-62 steel 1500 cubic meter spherical tank was one of the major technical equipment scientific and technological research projects. The Lanzhou Petrochemical Machinery Plant, Daqing Research Institute, Daqing Petrochemical Plant and other units formed the subject research group. This large spherical tank was built at the Daqing Petrochemical Plant in November 1993 and has been operating safely for several years. The successful development of fully domestically produced ethylene ball cans has broken the long-term import of low-temperature ethylene ball cans from abroad.
Third, the "three-machine" production of ethylene achieved zero breakthrough in domestic production. At present, only a few countries in the world have the ability to design and manufacture cracked gas compressors, propylene compressors and ethylene compressors. In 1997, relying on the Daqing ethylene modification and expansion project, Shenyang Blower Factory and Hangzhou Steam Turbine Plant successfully developed cracking gas compressors and propylene compressors.
China's self-developed cracking gas compressor adopts the self-developed scientific research results of the Shenyang Blower Factory over the past 20 years and has developed a number of mature new technologies and design experiences. The performance has completely reached the advanced level of contemporary international similar products. The manufacture of cracking gas compressors and propylene compressors has succeeded in replacing foreign imports and achieved a breakthrough in the localization of large-scale ethylene plants.
China's large-scale ethylene plant has a large market potential Zhang Fuqin, president and senior engineer of the China Petroleum Planning Institute, said that China’s ethylene project will develop 800,000 to 1 million tons of equipment, including the expansion of the existing 400,000 to 45 Million tons of equipment and new large-scale ethylene equipment. He estimated that China's ethylene production capacity in 2005 will be 9 million tons. In 2010, China's ethylene demand will reach 25 million to 26 million tons, and in 2010 the production capacity will reach 14 million tons, which can only meet 55% of domestic demand; In 2020, China's ethylene demand will reach 37 million to 41 million tons, and the production capacity will reach 23 million tons, which can only meet about 60% of domestic demand. The increase in production capacity is far from meeting the needs of consumption. One of the key reasons for this is the lack of large-scale ethylene equipment.
According to the preliminary forecast, by 2010 China will need to add about 8 sets of 800,000 to 1 million tons of ethylene complete sets of equipment, and by 2020 there will be an additional 9 sets. While building a set of one million tons of large-scale ethylene complete sets of equipment, the total investment is generally more than 20 billion yuan. In the ethylene construction project, the equipment cost accounts for about 30% of the total investment, and the cost of each large-scale ethylene equipment will reach about 7 billion yuan. Therefore, there will be equipment market demand of about 56 billion yuan during the “Eleventh Five-Year Plan†period. "There will be 63 billion yuan in equipment market demand during the period."
At present, China has approved the construction of large-scale ethylene projects are: Zhejiang Zhenhai Petrochemical 1 million tons / year ethylene project, a total investment of 21.5 billion yuan, completed in 2009; Quanzhou, Fujian 800,000 tons / year ethylene project, a total investment of 26.6 billion yuan , Completed in 2008; Tianjin Petrochemical 1 million tons/year ethylene project, total investment 20.1 billion yuan, completed in 2008; Sichuan Chengdu 800,000 tons/year ethylene project, total investment 21 billion yuan, built in 2010; Lanzhou 600,000 tons/year The ethylene renovation project, with a total investment of 6.3 billion yuan, was completed in 2006; the Xinjiang Dushanzi Petrochemical 1 million-ton/year ethylene project, with a total investment of 26.2 billion yuan, was completed in 2008 (for details, see related link 3).
In addition, ethylene projects that are undergoing preliminary preparation include Guangzhou Petrochemical's 800,000-ton ethylene project, Fushun Petrochemical's 800,000-ton ethylene project, Wuhan Petrochemical's 800,000-ton ethylene project, and Dalian's 800,000-ton ethylene project.
The significance of localization of large-scale ethylene equipment First, the realization of large-scale production of ethylene equipment will increase the core capabilities of equipment manufacturing.
Wang Tingjun said that in recent years, Sinopec has been relying on key projects to take the lead in using a large number of domestically produced ethylene complete sets of equipment. These major equipments have been used in Sinopec's Yanshan, Yangtze, Shanghai, Qilu and other ethylene transformations, and the localization rate of 600,000-ton ethylene equipment has reached about 70%. Due to major breakthroughs in localization of major equipment, Sinopec has mastered a large number of petrochemical equipment design and manufacturing core technologies with independent intellectual property rights, and has realized the design and manufacture of many key and core equipment in the petrochemical package equipment.
The localization of large-scale ethylene plants has promoted the development of the equipment manufacturing industry and the adjustment of product structure. A number of large-scale equipment manufacturers, including Yizhong, Shengu, Hangzhou Steam, Hangzhou Oxygen, Lanzhou Petrochemical Machinery Plant, etc., have gained practice in independent innovation. And opportunities for improvement have become the backbone of the domestic equipment manufacturing industry.
Second, the combination of technology and trade will increase the level of domestic equipment manufacturing.
In recent years, in order to increase ethylene production, several new large-scale ethylene projects of 800,000 to 1 million tons have been built, such as BASF in Nanjing and Germany, Shanghai and British Petroleum, Huizhou in Guangzhou and Shell in the Netherlands, and Exxon in Fujian and the United States. Take joint ventures and cooperation to improve the overall technical level of the device.
Wei Yongbin, director of the China National General Machinery Industry Association and director of the China National Machinery Industry Federation, believes that it is still not practical to use domestically produced equipment for the million-ton ethylene plant. However, it is necessary to increase the level of domestic equipment manufacturing by taking the road of integration of technology and trade. can be realised. At the same time, it is also possible to adopt a risk-sharing approach. In each set of key equipment, there is an iconic localized product. By combining the key domestic equipment in several sets of equipment, a localized ethylene plant can be equipped. In the next five years, China will rely on a number of large-scale ethylene projects to support the project, and introduce domestic key technologies for digestion, absorption, re-innovation and independent development to realize the localization of one million tons of large-scale ethylene equipment.
Third, manufacturing units and users form a strong joint research.
In recent years, in order to achieve breakthroughs in the localization of major technology equipment, more and more companies have established various types of technological innovation alliances with universities and research institutes, and at the same time formed investment and financing for some large enterprises, companies, manufacturing units and users. The combination of strengths and other forms of research will promote the efficient allocation and integration of scientific and technological resources.
Zhang Fuqin pointed out that in order to speed up the process of localization and industrialization of large-scale ethylene equipment, enterprises must intensify technological innovation, put technological innovation and develop new products in a prominent position, gradually increase investment in scientific research and development, and strive to enhance technological development and the introduction of digestion and absorption. Re-innovation capabilities, key breakthroughs in key technologies and equipment, development across the board, and integration of equipment design, manufacturing, after-sales service, and quality assurance systems.
Dr. Zhang Xiaofeng, the deputy general manager of Beijing Sino-Weissen Science and Technology Service Co., Ltd., who is engaged in petrochemical engineering and technical services, believes that the weak capability of independent innovation of equipment manufacturing companies is also one of the problems that currently restrict the localization of major petrochemical equipment.
After more than 20 years of major equipment tackling, China's equipment manufacturing enterprises have greatly enhanced their market awareness and competition awareness. In particular, many companies have actively digested and absorbed foreign advanced technologies, and their technologies and equipment have reached or approached the international advanced level. For example, China First Heavy Machinery Group has mastered the smelting, forging, welding, inspection and other manufacturing technologies of hydrogenation reactors; Shenyang Blower Factory has the capability and performance of designing and manufacturing complete petrochemical large-scale centrifugal compressors.
However, on the whole, the equipment manufacturing industry still has the phenomenon of weak research and development capabilities and low management level, which restricts the development of localization of equipment. For example, key petrochemical equipment such as gear assembly centrifugal compressors, large extrusion granulators and PTA oxidation reactors are still being imported.
How to improve the competitiveness of China's ethylene plant? Zhang Fuqin suggested that the government should adopt the necessary coordination and organization to further improve the support system for independent innovation policies; domestic ethylene equipment should leapfrog in environmental protection, energy conservation, and large-scale development; it must rely on external forces to complete the research of China's ethylene complete sets of equipment.
