vacuum distillation

The scheme of the integrated regeneration method for used mineral motor oils (UMMO) has been developed, according to which M-10DM and NORMAL 15W40 used oils were regenerated. A study on changes in physico-chemical properties, qualitative and elemental composition was carried out, and a mathematical model of the process was built. The further applications of the obtained products were proposed. Based on the obtained results, the technological scheme and flow chart of UMMO integrated regeneration were developed, and the process material balance was calculated.

The physico-chemical properties and the group composition of the used mineral motor oils M-10DM and NORMAL 15W40, as well as the fractions obtained as a result of their vacuum distillation, have been studied. The results of IR spectroscopy and XRF analysis are presented. The change in the composition and properties of the fractions distilled from used oils under vacuum has been described.
