Processing technology route for lubricant base oils
Thread Content

The traditional three-step process has limited adaptability to changes in raw materials and product structure, and many companies are considering adopting the hydrogenation route. The hydrogenation process includes: using hydrocracking and hydrotreating to improve the viscosity index and remove impurities, using catalytic dewaxing to lower the pour point, and using hydrofining to enhance stability. What are the other processing technology routes for lubricant base oils to meet current and future demand for base oils?
Thank you for your active participation; it would be even better if you could discuss the advantages and disadvantages of the device, as well as the types of raw materials and products used. Thank you! ! !
The wax oil cracking unit, together with the hydrogenation isomerization, dewaxing and deparaffinization unit, is used to produce base oil
Shell’s process involves going straight from hydrorefining to hydroisomerization, which can reduce investment costs; however, it increases operational complexity and makes the control systems more intricate
That’s exactly what the small solar system does at Bohui – it operates using such a device. Is there any difficulty in operating it? Hydrocracking serves to moderate the cracking properties, and the temperature rise during isomerization isn’t high. The interlocks are not complicated either; they are just the usual interlocks found in hydrogenation units
There are many units in China that combine wax oil cracking units with hydrogenation isomerization and dewaxing units; Chevron, Shell, ExxonMobil, the Chinese Academy of Petroleum Sciences, and the Fushan Research Institute all possess this technology. It’s not a proprietary technology – the systems are more or less similar across different manufacturers.
