[Ten years of development of chemical equipment] 1012-2023 Sinopec’s first domestic polypropylene axial flow pump was successfully tested in Anqing Petrochemical

Thread Content

Chemical technology has developed greatly in the past ten years, praising China's prosperity and strength. It is more lively and exciting with everyone's participation. Everyone is welcome to participate in more forum exchanges and discussions. July fires, pay attention to fire prevention. In May 2023, the 300,000 tons/year polypropylene unit extrusion granulator of the Anqing Petrochemical Refining and Conversion Industry Structural Adjustment Project successfully tested once and produced qualified pellets, realizing the domestic axial flow pump to "break the ice" in Sinopec's polypropylene unit. Anqing Petrochemical's 300,000 tons/year polypropylene unit is one of the key units in the oil refining and conversion project. Its smooth production and sales play an important role in the company's diversification of chemical products and improvement of its overall competitiveness. The axial flow pump is the heart of the polypropylene device, with harsh application environments and high manufacturing technology requirements. Since the implementation of the Refining and Conversion Industry Structural Adjustment Project, Anqing Petrochemical has actively responded to Sinopec’s opinions on the localization of key equipment for the project, adhered to the “active, prudent, advanced and reliable” localization policy, and adjusted the three large-flow axial flow pumps of the polypropylene unit originally planned to be imported to domestically produced. In order to speed up the progress of research, Anqing Petrochemical has repeatedly organized axial flow pump experts to conduct research on domestic first-line enterprises, carry out technical exchanges and demonstrations, and work together to * * Hefei Huasheng Pump and Valve Co., Ltd., a "little giant" company that specializes in new technologies, made every effort to break through the "stuck neck" technology, strengthened the quality control of key materials and parts, and finally successfully realized the localization of axial flow pumps. It is reported that the Anqing Petrochemical Refining and Conversion Industry Structural Adjustment Project has also realized the localization of extrusion granulation units, circulating compressors, circulating gas compressors and other equipment, with the equipment localization rate reaching more than 90%.
