In recent years, the domestic large-scale petrochemical equipment manufacturing industry has seen rapid growth. Particularly, outstanding achievements in the manufacture of key equipment such as polyester complete sets of equipment and large-scale ethylene oxide generators have caused the global petrochemical industry to attract more and more attention. Actively changing the existing market supply pattern. Sinopec Nanhua Chemical Machine Factory (hereinafter referred to as Nanhua) is a member of the army that promotes the localization of large-scale equipment in the industry. Once upon a time, domestic polyester equipment was foreign goods. Until 1995, South Chemicals and China Textile Institute cooperated to undertake the task of 30% localization capacity expansion of Yizheng Chemical Fiber's 100,000 tons/year polyester plant; at the beginning of 1999, it also took the lead in the development of key equipment for polyester plants in China. An esterification reactor and a low viscosity disc reactor. With more than ten years of innovation and development, Nanhua Machinery has become a mainstream supplier in the domestic polyester industry. At the same time, it has also successfully forcibly retired foreign manufacturers, breaking the monopoly of multinational companies. At the beginning, when China imported foreign polyester equipment, it paid a high price, and since the South China Chemicals realized the localization of key polyester equipment, the investment in polyester project construction has dropped drastically, and the construction period has been reduced by about half. To this end, when Zhang Guobao, deputy director of the National Development and Reform Commission and director of the National Energy Administration spoke about independent innovation in China's equipment manufacturing industry, he specifically mentioned: “In the past few years, due to the localization of polyester complete sets of equipment, China has saved investment in polyester projects. More than 100 billion yuan.". Up to now, Nanhua has produced a total of more than 120 sets of polyester plants with a maximum annual production capacity of 500,000 tons and a total annual production capacity of nearly 30 million tons, of which more than 10 sets of key equipment are exported, equivalent to an annual production capacity of more than 2 million tons. Large-scale ethylene oxide reactors are key large-scale equipment in petrochemical equipment. In 2009, under the strong support of Sinopec Group and the Department of Materials and Equipment, Sinopec and Sinopec Engineering Construction Company (SEI) cooperated with Yangzi Petrochemical's 180,000 tonne/year ethylene oxide reactor for local manufacturing tasks. After more than two years of research, Nanhua has overcome a series of difficulties and successfully used the reactor. At present, Nanhua has produced 10 sets of ethylene oxide reactors with a market share of about 75%. Reviewing the development history of South Chemicals, the four major petrochemical equipment technology innovations are signs, showing four distinct development stages. First, China successfully manufactured China's first multi-layered high pressure vessel in 1956. Premier Zhou Enlai personally issued the State Council's awarding order. Nanhua became the "hometown of China's first high-pressure vessel." Second, it was successfully developed in the early 1980s. The four key urea equipment won the first prize for the State Council’s major localization of major technology equipment. Premier Li Peng presented the prize personally. Third, in the mid-1990s, it successfully developed key sets of polyester equipment . Premier Wen Jiabao made important instructions and fully affirmed the polyester technology. The successful enlightenment and valuable experience of autonomy and equipment localization; Fourth, in 2011 successfully developed the petrochemical high-end large-scale equipment ethylene oxide reactor. The commendations and instructions of the three premiers of the Republic have inspired Nanhua to follow the established direction on the road to the localization of large-scale petrochemical equipment. This is to insist on independent innovation and aim at foreign monopolies, conquering the biggest and the most difficult. The reason why Nanhuan has repeatedly made achievements in the localization of large-scale petrochemical plants is because the company pays full attention to its own construction and keeps pace with the times. In terms of supporting the concept, it not only pays attention to the historical accumulation and inheritance of technology, but also embeds long-term accumulated experience and technology in all aspects of the manufacturing process. At the same time, it also pays attention to the introduction, digestion and absorption of new technologies, and vigorously promotes independent innovation to adapt it to today’s large-scale petrochemicals. New device needs. At present, China’s general petrochemical equipment has excess manufacturing capacity, while major petrochemical equipment has insufficient manufacturing capacity and some key petrochemical equipment still rely on imports. Therefore, during the “Twelfth Five-Year Plan†period, South Chemicals will continue to focus on the transformation and upgrading of the petrochemical industry to help promote low-carbon and green petrochemicals as guidelines, to create national brands, and to carefully build manufacturing bases, localization bases, and products for domestic large-scale petrochemical equipment.
