  • Why do we regenerate used motor oil?
  • The used motor oils are contaminated by contaminants and impurities resulted from undesirable oxidation processes: sediment, water, metallic particles and degraded additives. The regeneration of used oil implies the removal of the contaminants.
  • How lubricating oil is regenerated?
  • Membrane technology is another method for regeneration of used lubricating oils. The process is carried out at 40 °C and 0.1 MPa pressure. The process is a continuous operation as it removes metal particles and dusts from used engine oil and improves the recovered oils liquidity and flash point.
  • How to regenerate used oil?
  • The regeneration of used oil implies the removal of the contaminants. There are several recycling methods; the present research follows the basic steps: acid treatment to remove gums, greases etc., sedimentation/decantation, bleaching, neutralization, sedimentation/decantation and filtration.
  • What is used oil management system in Romania?
  • In Romania, by HG 235/2007, the producers and importers are required to ensure the organization of used oils management system. The ways of used oils processing for reuse are: regeneration (re-refining), thermal cracking, gasification, mild/severe reprocessing, combustion.
  • Does acid treatment of used motor oil protect the natural environment?
  • At the same time, it represents a viable way of protecting the natural environment. The research investigates the effect of different alcohols used in acid treatment of used motor oil and the influence of the bleaching treatment on the properties of the regenerated oil.
  • How to recycle engine oil?
  • The conventional methods of recycling of waste engine oil either requires a high cost technology such as vacuum distillation or the use of toxic materials such as sulfuric acid. These methods also produce contaminating by-products which have highly sulfur levels. Acid-clay has been used as a recycling method for used engine oil for a long time.
