The invention patent “hydrolysis method in the synthesis technology of ultra high molecular weight polyacrylamide†is a problem that Daqing Refinery has to solve the problem of high salinity and difficult handling of the wastewater from Daqing Oilfield. It is developing water-soluble high molecular weight with independent intellectual property rights. The innovation of salt-tolerant polyacrylamide synthesis technology and research and its accompanying engineering technology are formed in consideration of the need to realize large-scale continuous production, increase the effect of hydrolysis, and realize the concept of automatic control.
The patent proposed for the first time a dynamic mixed hydrolysis reaction mode between polyacrylamide gel particles and alkali, developed a one-step hydrolysis reactor, achieved a major breakthrough in engineering technology, and formed an industrialized complete production technology for high molecular weight and salt-resistant polyacrylamide, achieving scale. Chemical industry production.
The China Patent Award was established in 1989 and is the highest award in the field of patents issued by the Chinese government. It aims to vigorously implement the national intellectual property strategy, enhance the awareness of intellectual property protection in the entire society, promote the improvement of China’s independent intellectual property quality and structural adjustment, and improve China's ability to create, use, protect and manage intellectual property. The China Patent Gold Award is jointly awarded by the State Intellectual Property Office and the World Intellectual Property Organization to the winning patentee. The State Intellectual Property Office issues certificates and certificates to the patentee and the invention (design) who were awarded the China Patent Excellence Award. So far, CNPC has participated in the 10th China Patent Awards and has won 6 gold awards and 28 outstanding awards.
This patent award is the first award since China promulgated and implemented the "Outline of the National Intellectual Property Strategy" last year. The overall level of the participating projects was relatively high, and the number of declared projects and enterprises and institutions participated in the project has increased significantly compared with the previous session. From now on, the selection period for the China Patent Award will be changed from two years to one year.
