Technology Research on Molecular Distillation Separation of Renewable Waste Lubricating Oil

Based on the research of the molecular-distillation technical conditions for the renewable waste lubricating oil, the optimal technology and processes were studied and obtained with a pilot-scale molecular distillation device. The results could provide a strong technical basis for the reduction and recycling-separation of the renewable waste lubricating oil, and also for the energy-saving and emission-reduction. In addition, the economic and development prospect of this method was described and analyzed.
