【Ten Years of Great Progress in Chemical Technology】The first industrial application of domestic low-viscosity PAO lubricant production technology from 2017 to 2023
Thread Content
Over the past decade, chemical technology has seen remarkable progress; let’s celebrate the prosperity and strength of modern China. By contributing our ideas, we can foster more active participation from everyone. HaiChuan becomes even better with your involvement – we welcome all to join in the forum discussions. Everyone should pay attention to safety and know how to handle emergencies. ********************************************* Polyalphaolefin synthetic oil (abbreviated as PAO) is internationally recognized as an ideal base oil for producing high-quality, specialty lubricants, thanks to its excellent viscosity-temperature properties and flowability at low temperatures. Among them, low-viscosity PAO products, with their good viscosity-temperature properties, appropriate high-temperature viscosity, excellent low-temperature flowability, and thermal oxidation stability, have become the synthetic lubricant base oils with the best performance at present. On January 3, 2022, the industrial demonstration unit for low-viscosity PAO lubricants based on Kunlun Lubrication’s continuous clean production technology was successfully commissioned. This marked the first industrial application of such technology for producing low-viscosity PAO lubricants in China, breaking the foreign technological monopoly and playing a significant role in accelerating the upgrading of base oils used in lubricants in our country. To date, all systems are operating stably, and the production trial run is progressing smoothly as planned.
The demand for high-performance PAO in our country has increased significantly, with low-viscosity products accounting for over 80% of the total demand for PAO, making them the most widely used variety at present. Since PAO is related to important fields such as **, aerospace, and advanced manufacturing that are crucial for ** strategic development, foreign companies have imposed strict technical restrictions, making it urgent to work on developing core technologies. The integrated technology for the continuous clean production of low-viscosity PAO lubricant base oils was jointly developed by the Petrochemical Research Institute of China National Petroleum Corporation (hereinafter referred to as the Petrochemical Research Institute) and Kunlun Lubrication. It represents an important achievement of the key research and development project titled “Research and Application of Key Technologies for the Production of High-Performance Lubricants”. In 2020, Kunlun Lubricants and the Petrochemical Research Institute worked closely together to build China’s first industrial facility for producing low-viscosity PAO base oil on a scale of 10,000 tons per year – the Kunlun Lubricants 10,000-ton/year low-viscosity PAO industrial demonstration plant. Together, they overcame technical challenges such as the non-steady-state complexation of polymerization catalysts and intense exothermic reactions. They also designed and completed the construction and commissioning of a pilot-scale production facility for PAO catalysts, ensuring the smooth progress of the industrial trials. Filling technical gaps and providing technological support for high-end manufacturing: After four years of intensive research and development, and by utilizing China’s first industrial testing facility for 10,000-ton batches of low-viscosity PAO base oil, the team’s repeated experiments and ongoing process optimizations have yielded significant results. By the end of 2021, the project had completed all its industrial testing tasks and received high praise from industry experts.
