[Ten years of development of chemical equipment] 808-2011 Ningbo Heyuan 350,000 tons/year polypropylene plant loop reactor
Thread Content
Looking at the great development of chemical equipment in the past ten years, I praise the prosperity of China and wish everyone a happy new year. May the whole family be safe and healthy. It will be more lively and exciting with everyone's participation. Welcome everyone to participate in more forum exchanges and discussions----------------------------------------------------------------- On December 13, 2011, the Ningbo Heyuan 350,000 tons/year polypropylene unit loop reactor, the polypropylene loop reactor with the largest annual processing capacity in China, was successfully manufactured and shipped by Maoming Gravity Company and will be delivered early next year. The scale of the polypropylene plant is 350,000 tons/year, and the reactor is designed and manufactured with a capacity of 400,000 tons. This 100% domestically produced device was designed by Sinopec Engineering and Construction Corporation (SEI) and has independent intellectual property rights. The successful localization of loop reactors not only improves the level of domestic equipment manufacturing, but is also of great significance to the development of my country's polypropylene process technology and the research and development of new grades of polypropylene. It will significantly reduce material, manufacturing, and transportation costs, and provide * * Save a lot of foreign exchange.
Ningbo Heyuan's 350,000 tons/year polypropylene loop reactor is the longest polypropylene loop reactor with the largest annual processing capacity built in China so far. There are two loop reactors in total, each consisting of six 51-meter-long straight pipes and 180-degree elbow connections, with a total weight of 644.87 tons. It is not only bulky and complex in structure, but also has very demanding production requirements. Participating in this research has also enabled Maoming Gravity Company to achieve a great harvest in the development and application of high-tech equipment manufacturing, becoming a milestone in Maoming Gravity Company’s localization process of loop reactors. In the process of researching key problems, they have developed a number of new manufacturing technologies, some of which are on their way to * * Apply for a patent. It is understood that Maoming Gravity Company is a pioneer in the localization of loop reactors. It has been manufacturing local loop reactors for more than ten years since the 1990s. The company has successively manufactured more than 60 loop reactors for large-scale polypropylene and polyethylene units of Maoming Petrochemical, Zhenhai Refining, Qingdao Refining, Ningxia Petrochemical, Hohhot Refining and other Sinopec and PetroChina and local large petrochemical enterprises. The domestic market share has reached more than 90%. The manufacturing level is comparable to that of large international companies. The loop reactor has become the company's flagship product. At the recent inspection and acceptance ceremony of this equipment by an expert group composed of domestic petroleum and chemical equipment experts, the experts unanimously believed that the design of this reactor met the requirements of the process patentee, and the overall condition of the equipment met the design requirements and fully complied with the requirements. * * Relevant standards and specifications, quality meets technical requirements.
