Definitions

  • the invention relates to a method and an installation for regenerating used lubricating oils.
  • Lubricating oils generally undergo modifications and alterations during their use, which implies their more or less frequent renewal.
  • oils After use, these oils generally contain solid residues, additives, combustion residues, etc ....
  • This installation includes two tanks, allowing two treatments, one with soda and the other with the ground, and two centrifuges, ensuring the separation, one of water and the other of used earth, of the oil to be treated.
  • the objective of the present invention is therefore the development of a process for the regeneration of lubricating oils little or non-polluting used and whose implementation can be done in good economic conditions.
  • the invention relates to a process for regenerating used lubricating oils comprising a step strong base treatment.
  • the method comprises the steps of successive object processing of claim 1.
  • the invention also relates to an installation for regenerating used oils allowing the implementation of the process mentioned above.
  • the vacuum distillation unit is associated with a column bottom exhaustion evaporator.
  • the used oils collected can have various origins, it can be for example engine oil, oil gears or hydraulic oil, turbine oil, etc.
  • the regeneration process of the invention essentially aims at the elimination of light components, such like gasoline, diesel and water, but cannot remove components as heavy as the oils themselves but having different physical properties. It could be, for example, fuel whose elimination or treatment could only be obtained by a complete refining process.
  • Chlor Test which makes it possible to detect the presence of chlorides.
  • a hardened copper wire in used oil is presented to the flame.
  • a greenish flame indicates the presence of chlorides.
  • the "Drop Test” detects the presence of fuel. A drop of oil is deposited on a chromatographic paper. A concentric spot with a yellowish halo indicates the presence of fuel.
  • the "Fat Test” detects the presence of fatty acids in oils. 2 ml of used oil is heated in presence of a soda tablet: when the oil freezes, after cooling, this means that fatty acids are present.
  • Preheating means 3 bring the oils taken from the tank 2 to a temperature between 140 and 160 ° C.
  • a base stored elsewhere in a tank 4 is supplied and mixed by means 5 with the used oils. preheated.
  • a quantity of pure base of between 1 and 3% by mass is added to the used oils.
  • This rate can advantageously be specified as a function of the quality of the used oils.
  • Water and light hydrocarbons are extracted and the remaining mixture is directed to a unit 8 for extracting diesel (stripping). This elimination is carried out by distillation in a column.
  • the gas oil 9 is then discharged and the remaining mixture is led to a distillation column 10 allowing the fractionation of the mixture into lubricating base oil sections and separation of the residue where all are concentrated the impurities.
  • Base oils can be separated at different levels depending on the number of cuts desired.
  • the distillation column 10 is a traditional vacuum column which allows the dissociation and the extraction of the residues, which are directed to an accumulation tank 14.
  • the residues 15 are then removed and are capable of being used, for example, as tar or bitumen for road construction. They can also be used as fuels.
  • the vacuum distillation column 10 is preferably associated with a bottom exhaustion evaporator. column 13 to improve its efficiency. Part of the energy required to raise the temperature used oils before the addition of the pure base preferably comes from the energy recovery carried out on the lubricating base oil sections 11, 12 of the column outlet 10.
  • the used oils are advantageously filtered during their recovery and when they leave the tank. storage 2, so as to eliminate the solid particles which they may contain.
  • the process and the installation of the invention therefore make it possible, from used oils, to obtain base oils of various reusable qualities, usable residues, water, light hydrocarbons and diesel.
  • This process provides a minimum recovery rate of 90%. This rate is the mass ratio of quantities of oils recovered by this industrial process, compared to that of oils recovered in the laboratory, in optimum conditions independent of any economic consideration.
  • the preferred embodiment uses the vacuum distillation column associated with an evaporator column bottom exhaustion. It is thus possible to obtain an oil cut recovery rate of excellent lubricant base, lower investment and operating costs compared to other processes known regeneration, to obtain regenerated oils as efficient as new base oils and to eliminate of these almost all metals.
  • the installation of the invention can be implemented easily under the best conditions of reliability.
  • Yield represents their yield (Mass ratio of the quantity recovered compared to the initial quantity of oil used to regenerate).
  • T.A.N. represents their acidity (acid number content).
  • VIS 40 ° C represents their viscosity at 40 ° C expressed in centistocks.
  • Color is expressed relative to standard reference colors. Plus the numeric value shown is weak, the better the color and appearance is a qualitative indication.
  • Ba represents barium, Ca calcium, Pb lead, Zn zinc, P phosphorus, Cr chromium, Fe iron and Si silicon.
