Ethylene is a basic chemical raw material for synthetic fibers, synthetic rubber, synthetic plastics, and 75% of petrochemical products are produced from ethylene. According to estimates by experts, the commissioning of a one-million-ton ethylene project can drive more than 100 billion yuan in downstream industrial investment. At the same time, ethylene's long industrial chain has penetrated into most industries such as textiles, clothing, automobiles, electronics, building materials, plastics, and chemicals.
Feng Shiliang, deputy secretary-general of the China Petroleum and Chemical Industry Association, believes that ethylene has a leading and core position in China's petrochemical industry, and its production has become an important indicator of the development level of a country's petrochemical industry.
China will produce ethylene for the world. From the end of the 1950s, Lanzhou Chemical Industry Co., Ltd. introduced foreign technology and equipment to build an ethylene production plant with an annual output of 20,000 tons. By the time Beijing Yanshan Petrochemical introduced 30,000 tons of ethylene equipment in 1976, the Chinese began to develop. Ethylene industry road. However, the rapid development of the ethylene industry has been a thing of the past 15 years. At present, China has built Yanshan, Shanghai, Yangtze, Qilu, Maoming, Daqing, Liaoyang, Jilin, Panjin, Fushun, Lanzhou, and other large petrochemical bases with ethylene as its leader, fundamentally changing the history of ethylene's long-term dependence on imports. By the end of 2006, China's ethylene output was 9.41 million tons, ranking the second in the world. It has surpassed Japan to become the second largest ethylene producer in the world after the United States.
In recent years, China’s rapid economic growth has generated a great demand for ethylene. When interviewed by reporters, Bai Yu, the deputy head of China Petroleum and Chemical Industry Planning Institute pointed out that in 1997, the country’s ethylene production was 3.585 million tons. In 2005, China had 19 sets of ethylene plants with a production capacity of 7.07 million tons per year. Consumption was 17.4 million tons, and the domestic market satisfaction rate was 43%. By the end of 2006, China's ethylene production had reached 9.41 million tons. In the past 15 years, the consumption of ethylene products in China has been in a period of rapid growth, with the average annual consumption growth of 16.1%. Bai Ji believes that China's ethylene demand during the "Eleventh Five-Year" period will continue to maintain stable growth. It is expected that by 2010 China's ethylene production capacity will reach 17 million to 18 million tons, and the output will be 14.5 million tons/year, and the ethylene self-sufficiency rate will reach 58. %.
Now that China is a “world factory,†Chinese-made products are supplying the world, so in a sense China is producing ethylene for the world. The Houston SRI Consulting Company has issued a report that the overall level of China's ethylene industry has rapidly entered the ranks of advanced countries in the world. China's recently constructed modern ethylene and petrochemical complexes are extremely competitive for Saudi Arabian producers, even with raw material cost advantages.
The world-class equipment and scale of "introduction-digestion and absorption-integrated innovation-independent innovation" is a long-term principle of China's ethylene industry. The characteristics of modern ethylene production equipment are that the larger the scale, the lower the cost. While introducing the most advanced ethylene equipment, Sinopec Group, the giant of China's ethylene industry, has carried out technological transformation and reconstruction of the small and medium-sized ethylene plants introduced in the past. Not only has the average size of the device more than doubled, but it has also achieved independent R&D on the basis of absorbing imported technology and formed a number of independent core technologies, proprietary technologies and supporting technologies. Because of the independent technology, the localization rate of ethylene equipment has been significantly increased, which has promoted the localization of major equipment.
The ethylene industry is a technology-intensive industry and requires high reliability of equipment. In accordance with the idea of ​​"equal emphasis both on domestic and international process technology and localized equipment", the localization rate of ethylene equipment has reached more than 80%, and many equipment quality has reached the world's advanced level. Through independent innovation and cooperative development, Sinopec has been able to use its own technology to build a million-ton ethylene plant.
In recent years, the level of technical equipment in China's ethylene industry has been significantly improved, and large-scale ethylene cracking furnaces, polypropylene, acrylonitrile, catalytic pyrolysis of heavy raw materials, SBS elastomers and other complete sets of technologies have been successfully developed, and some special equipment have been domestically produced. The one-million-ton ethylene pyrolysis gas compressor technology has reached or reached the international advanced level. The "three doses" are basically based in China and are at or near the advanced level in the world. The construction of large-scale ethylene projects was introduced from complete sets, and only technological packages and some key equipment were introduced; from general foreign contracting to domestic self-design, procurement and organization, many technologies were exported to foreign countries. At present, China's catalyst technology has been exported to the United States, and the pyrolysis furnace technology jointly developed by Sinopec and US companies has promoted more than 30 units. Experts pointed out that the technology and scale of China's ethylene industry have reached the world level.
The localization of large-scale ethylene equipment has promoted the development of the petrochemical equipment manufacturing industry and the adjustment of product structure, bringing with it the inclusion of China’s No. 1 Heavy Machinery Group, Shenyang Blower Factory, Hangzhou Steam Turbine Plant, Hangzhou Oxygen Corporation, and Lanshi Machinery Equipment Co., Ltd. A number of large-scale backbone enterprises. At the same time, the localization of large-scale ethylene equipment has nurtured a number of strategic suppliers with international standards for the engineering construction of China's petrochemical industry, which has enhanced the ability of China's petrochemical equipment industry to participate in international market competition.
Ethylene industry cluster will be formed Looking at the development history of China's ethylene industry, the first development is the scale, at the same time, digest and absorb the independent innovation of imported technology, and realize the localization of independent technology and major equipment. Today, China's ethylene industry is facing a huge space for development. At present, although China’s ethylene production capacity has leapt to the second place in the world, China is also the world’s largest consumer market for petrochemical products. In 2010, China’s ethylene self-sufficiency rate reached 58%.
According to Feng Shiliang, in accordance with the requirements of China's "Special Plan for Medium and Long-Term Development of the Ethylene Industry", accelerating the development of the ethylene industry will become the focus of the "11th Five-Year Plan" period. It is understood that the highlight of the development of China's ethylene industry will be to increase the total amount of ethylene and form a group of world-class ethylene production bases.
Bai Yan predicted that in the future, the construction and transformation of ethylene and downstream petrochemical plants in China will select advanced technologies to accelerate the process of localization and industrialization of major ethylene equipment. At the same time, efforts will be made to achieve key breakthroughs in the key technologies and equipment for the ethylene industry, promote the use of heavy feedstock oils to produce olefins, and also use coal to produce ethylene. Energy consumption and material consumption will reach world advanced levels.
At present, China’s Pearl River Delta, Yangtze River Delta, and Bohai Bay’s “two continents and one bay†region have concentrated three million-ton ethylene production bases in Shanghai, Nanjing, and Maoming, and two 800,000-ton-class vinyl bases in Yanshan and Qilu. . Together with the three million-million-ton oil-refining ethylene chemical integrated bases in Fujian, Zhenhai and Tianjin under construction, the ethylene production capacity in China's “Two Islands and One Bay†region will soon surpass Tokyo Bay and become the world’s foremost ethylene industrial cluster.
