Abstract
A process for recovering a biological fraction from the regeneration of waste oils is disclosed, including basification, recover of the aqueous fraction and acidification thereof Such steps are performed on the flows coming from the fractional distillation step in packed column of the regenerated waste oils. Preferably, the process is performed batchwise, wherein each fraction coming from the fractional distillation of regenerated waste lubricants undergoes the process separately from the other fractions.
