Definitions

  • the invention relates to a method and a lubricating oil regeneration plant used.
  • Lubricating oils generally undergo modifications and alterations during their uses, which implies their renewal more or less common.
  • oils After use, these oils contain generally solid residues, additives, combustion residues, etc.
  • This installation includes two tanks, allowing two treatments, one to the soda and the other to the earth, and two centrifuges, ensuring the separation, one of the water and the other of the used earth, oil to be treated.
  • This type of process allows the recovery of a part of the used oil, but generates waste not reusable highly polluting.
  • the recovery rate of the installations manufacturers implementing these processes does not exceed not 85% and their cost of implementation is high.
  • the objective of the present invention is therefore the development of an oil regeneration process used lubricants with little or no pollution and the use of which can be done in good conditions economic.
  • the invention relates to a method of regeneration of used lubricating oils comprising a strong base treatment step.
  • the method comprises the steps of successive treatments object of claim 1.
  • the invention also relates to an installation of regeneration of used oils allowing the setting in work of the process mentioned above.
  • the vacuum distillation unit is associated with a bottom depletion evaporator column.
  • the used oils collected may have various origins, it can be for example engine oil, gear oil or hydraulic oil, turbine oil, etc ....
  • the regeneration process of the invention essentially aims at eliminating light components such as than gasoline, diesel and water, but does not allow to remove components as heavy as the oils themselves but having different physical properties. he could be, for example, fuel whose elimination or treatment could only be obtained by a process of complete refining.
  • the "Drop Test” detects the presence of fuel. A drop of oil is placed on a paper chromatographic. A concentric spot with a halo yellowish indicates the presence of fuel.
  • the "Fat Test” detects the presence of acids fat 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 carry the oils taken from tank 2 at a temperature between 140 and 160 ° C.
  • a base stored elsewhere in a tank 4 is added and mixed by means 5 with waste oils preheated.
  • a quantity of pure base between 1 and 3% by mass is added to the used oils.
  • This rate can be advantageously specified depending on the quality of used oils.
  • Waste oils brought to a high temperature, added with strong base, feed a unit 6 extraction of water and light hydrocarbons by expansion (flash).
  • flash feed a unit 6 extraction of water and light hydrocarbons by expansion (flash).
  • the evaporation of water is produced by the sudden expansion of the mixture in a balloon.
  • 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 diesel 9 is then evacuated and the remaining mixture is leads to a distillation column 10 allowing the fractionation of the mixture into base oil cups lubricants and the separation of the residue where concentrated all the impurities.
  • Base oils can be separated at different levels according to the number of cuts sought.
  • the distillation column 10 is a column traditional vacuum which allows dissociation and the extraction of residues, which are directed to a balloon accumulation 14.
  • the residues 15 are then removed and are susceptible to be used for example as tar or bitumen for the road construction. They can also be used as fuel.
  • the vacuum distillation column 10 is preferably associated with a bottom depletion evaporator column 13 to improve its efficiency. A part of the energy required to raise the temperature of used oils before the addition of the pure base comes from preference for energy recovery carried out on lubricating base oil cups 11, 12 from the outlet column 10.
  • Used oils are advantageously filtered during of their recovery and when they leave the reservoir of storage 2, so as to eliminate solid particles that they can contain.
  • the method and the installation of the invention allow therefore from used oils to obtain base oils of various reusable qualities, usable residues, water, light hydrocarbons and diesel.
  • This process provides a minimum rate of 90% recovery. This rate is the mass ratio of quantities of oils recovered by this industrial process, by compared to that of oils recovered in the laboratory, in optimum conditions independent of all considerations economic.
  • the preferred embodiment implements the vacuum distillation column associated with an evaporator column bottom exhaustion. It is thus possible to obtain a recovery rate in cut of base oil excellent lubricant, lower investment costs and operating compared to other methods of known regeneration, get regenerated oils too than new base oils and eliminate these almost all metals.
  • the installation of the invention can be implemented easily in the best conditions of reliability.
  • Yield represents their yield (Mass report 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.
  • the color is expressed in relation to colors of standard reference. The higher the numerical value indicated 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.
  • table c) makes bring out the superior quality of the base oil cuts obtained according to the invention.
  • contents in metals in the recovered oils are very inferior and the yield is more important. Plus all of the cuts is easily reusable.
