Abstract (en)
[origin: EP3098290A1] A process for the regeneration of waste oils is disclosed, comprising a fractioned distillation in a packed column (21) and hydrorefining and grinding of bitumen and any sediment from other steps, said grinding yielding a liquid fraction, collected as product, and a solid fraction, recycled to the first process steps. The oil to be regenerated is then fed to the process divided into two separate fractions, a better-quality one and a lower-quality one, containing more impurities, said better-quality fraction undergoing flash distillation, centrifugation and dehydration, to then be sent to the distillation packed column (21), while said worse-quality fraction undergoes homogenisation, grinding and decanting, the liquid phase which is obtained following these operations being mixed with the better-quality fraction and the solid phase being recycled to the homogenisation step. A plant for the implementation of the process is also disclosed. Such a plant comprises a packed distillation column (21) and a reactor (27) for hydrorefining and has two feeds (1; 2) of oil to be regenerated and at least one grinding unit (5) of the solid sediments and at least one centrifugal separator (13).
