Let’s give praise and encouragement to the achievements made in China’s chemical engineering technology and equipment; your participation in discussions is the greatest encouragement. **********************【Ten Years of Great Progress in Chemical Engineering Equipment】A continuously updated summary post is available – feel free to join the discussions: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** On June 10th, the project related to super-oil-affinity and water-repelling hollow fiber membranes, as well as high-efficiency lubricant film purification equipment, which was developed by Shandong Haihua Group Co., Ltd., Shandong Haihua Meitian Membrane Materials Co., Ltd., and Tianjin Polytechnic University, passed the evaluation of scientific and technological achievements organized by Tianjin Technology Property Rights Exchange Co., Ltd. An expert group composed of Hou Lian, an academician of the Chinese Academy of Engineering, and others unanimously agreed that this achievement is at the international leading level, and recommended further expanding its scope of application for verification. 　　In industrial production and the operation of mechanical equipment, high-quality lubricants are key substances that ensure the efficient and stable operation of such equipment. However, during use, these oils inevitably become contaminated with substances such as water, dust, and metal shavings, which causes their performance to deteriorate over time. This not only affects the reliability and service life of the equipment but also increases maintenance costs; it can even lead to serious safety accidents. Furthermore, in the purification of used oil, traditional processes often require a series of treatments such as centrifugation, vacuum heating for dehydration, and clay treatment in order to achieve satisfactory purification results. This leads to significant problems including complex process flows, high operating costs, and the generation of additional hazardous waste. Therefore, it is of great significance to develop an energy-efficient, efficient, and environmentally friendly oil dehydration and purification technology that can maintain the components of the oil as much as possible. 　　Based on this, under the leadership of Dr. Dai Haiping, a leading talent in industrial entrepreneurship from Mount Tai in Shandong Province, the project team developed a membrane filtration technology for the deep dehydration and purification of oil products under normal temperature and pressure. This technology has been put into practical use in various fields, filling a gap in the industry. Experts point out that its physical purification mechanism does not require chemical agents, and its energy-saving characteristics make it highly compatible with the **\"dual carbon\" strategy as well as the goals of a green circular economy and industrial support, thus offering broad application potential. 　　As a revolutionary physical purification method, the project’s core technology utilizes an original design for oil-loving and water-repelling membrane materials as well as adaptive backwashing technology, offering four innovative advantages in key performance indicators such as separation accuracy, energy consumption, and service life. First is the advantage of efficient separation: by utilizing the super-oil-loving and hydrophobic properties as well as the microporous separation characteristics of hollow fiber membranes, it is possible to effectively remove water and mechanical impurities from oils in one step at normal temperature and pressure ； Second is the advantage of being environmentally friendly: no chemical agents need to be added during the purification process, thereby completely eliminating the risk of secondary pollution ； Third is the advantage of easy maintenance and long service life: simple physical back-washing can effectively remove contaminants from the membrane surface, rapidly restore the membrane’s filtration efficiency, and significantly extend its useful life ； Fourth is the advantage of energy savings and reduced consumption; compared to traditional methods, this technology can significantly cut operational energy use and decrease the generation of hazardous waste. To date, this project has been granted 3 invention patents and 8 utility model patents, with its core technology winning the Geneva International Invention Gold Award.
