摘要 |
<p>Process for re-refining spent lubeoils, wherein a lubeoil freed from water and sludge forming impurities is subjected to a pre-destillation at reduced pressure and with a short residence time of the oil in the distillation column and is subsequently subjected to film evaporation under vacuum, in one or more wiped-film evaporators wherein the overhead product obtained with the film evaporator is subjected to an after-treatment after condensation and the heavy bottom product (residue product) of at least one film evaporator is at least partially recycled to the entrance of said film evaporator.</p> |
