Quality Assessment of Base Oils Obtained by Regeneration Technology from Wasted Lubricants

Abstract

The API 1509 standard contains a list of technological processes that can be used to obtain base oils. Base oils can also be obtained using the technology of multistage regeneration of wasted oils. The main requirement according to the classification of API standard 1509 is that the re-refined base oil must be free from harmful substances and contaminants that were formed during its previous use. There is no other information in the standard regarding the requirements for re-refined base oils. The article discusses various methods of assessing the quality of industrial batches of base oils of group I, obtained according to the licensed technology of the German company Fluid Solutions. The quality assessment was carried out both directly for base oils obtained using the regeneration technology, and for laboratory samples of market grade oils, the compositions of which included regenerated base oils.
