As of the time of the press release on the 8th, China's first linear low-density polyethylene (LLDPE) circulation gas compressor unit manufactured by Shenyang Blower Group Co., Ltd. is in full swing and is ready for shipment to Qilu Petrochemical. China's LLDPE production cycle gas compressor unit can only be purchased from abroad at a high price, and the technology has long been subject to human control, and it has finally been broken. From January 5th to January 13th, Shengu Group carried out performance and mechanical operation tests in four stages and achieved success. After testing, the drum compressor developed by Shengu Group has achieved a complete set of process from design, manufacture, installation and commissioning. It fully meets the design value. The design and structural design of the dry gas seal of the recirculating compressor unit is reasonable, the material selection is correct, and the control system is designed. It is simple and reliable. The product quality control and inspection plan are perfect, and it fully meets the requirements for long-period operation of the dry gas seal of the circulating gas compressor unit. The operation shows that the dry gas sealing performance of the circulating gas compressor unit is stable and reliable, and the running performance is good. The implementation of this important equipment manufacturing node of the Group has not only broken the long-term monopoly of the United States GE, Siemens Germany, Japan’s Mitsubishi Heavy Industries and other foreign companies, has filled the blank of the domestic technology, but also opened the way for the subsequent development of this type of product. Accumulated valuable experience. Experts said that the cycle gas compressor is a landmark high-end product in the petrochemical industry, marking a professional manufacturer's design ability, manufacturing capability and comprehensive ability. The cycle gas compressor unit is also the "heart" equipment of the LLDPE production plant. Due to the large gas processing volume, high inlet temperature and large amounts of powder and catalyst in the gas, the conditions for the impeller surface treatment are very demanding. In May 2010, Qilu Petrochemical Co., Ltd. responded to the call of the country to revitalize the national industry and promote the substitution of domestic imports of equipment, and actively discussed the localization of technology with the Shengu Group. After six months of unremitting efforts, in November of that year, LLDPE production equipment with a circulating gas compressor was included in China's major equipment research and development projects. After 13 months of research and development and manufacturing, the first domestically produced unit was finally born in the Shengu Group. This not only lays a solid foundation for the structural adjustment project of synthetic resin products of the key project of Qilu Petrochemical, which will provide an important guarantee for the large-scale economic development of synthetic resin products during the “Twelfth Five-Year Plan†period in China.
