Definitions
- the present invention relates to a method and a lubricating oil regeneration plant used with high performance.
- the object of the invention is therefore to propose such a process and the corresponding installation.
- a complementary addition of a strong base in aqueous solution due to 0.1 to 1% of pure bases by mass of lubricating oils is performed after step e).
- the amount of strong bases in aqueous solution can be between 0.5 to 3% of pure bases by mass used lubricating oils. This addition can be totally or partially cold or hot.
- the heating temperature of waste oils at regenerate between 120 and 250 ° C is a temperature at which the addition of the hot base is carried out in whole or in part.
- the used oils collected may have various origins. It can be, for example, oil engine, gear oil, hydraulic oil, turbine oil, etc.
- the regeneration process of the invention aims to eliminate light components, such as petrol, diesel and water, it allows also the elimination of degradation products from oil and additives but does not remove some components as heavy as the oils themselves and having different physical properties. he could be, for example, fuel oil elimination or treatment could not be obtained only by a complete refining process.
- Waste oil collected 1 having undergone with successful all of the tests come together in a tank 2.
- a base or a mixture of bases stored by elsewhere in a tank 4a is brought and mixed by means 5a to waste oils at temperature ambient between 10 and 40 ° C.
- Heating means 3 carry the oils taken from tank 2 and possibly mixed with the base, at a temperature between 120 and 250 ° C and preferably between 140 and 160 ° C.
- a base or a mixture of bases stored by elsewhere in a tank 4b is brought and mixed by means 5b to heated waste oils.
- an amount of pure bases between 0.5 and 3% by mass is added to waste oils.
- This rate as well as its distribution between the two cold and hot injection points, can be advantageously specified according to the quality of used oils and the nature of the base used.
- the base used is a strong base, preferably sodium or potassium hydroxide. We can also consider using a mixture of these bases.
- Waste oils brought to a temperature high, added with strong base, feed a water and oil extraction unit 6 light by triggering (flash).
- a water and oil extraction unit 6 light by triggering (flash).
- water evaporation is produced by expansion brutal mixing in a balloon.
- the diesel 9 is then discharged and the remaining mixture is led to a distillation column 10 allowing the fractionation of the mixture into sections lubricating base oils 11, 12 and separation of residue 15 where all the impurities are concentrated.
- Base oils can be separated at different levels depending on 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 accumulation tank 14.
- the residues 15 are then removed and are likely to be used, for example, as tar or bitumen for road construction. They can also be used as fuel.
- the vacuum distillation column 10 is preferably associated with a depletion evaporator column bottom 13 to improve sound efficiency. Part of the energy needed to the rise in the temperature of used oils before the flash preferably comes from recovery of energy carried out on the cuts of base oils lubricants 11, 12 of the column outlet 10.
- Used oils are advantageously filtered during their recovery and when they leave the storage tank 2, so as to eliminate the solid particles they may contain.
- An additional basic solution is added made at lower proportions than additions initials, before the flash, the additional addition being in proportions of the order of 0.1 to 1% by mass of pure bases compared to oils used lubricants. It can be done in different points of the corresponding installation in each case has an embodiment.
- This process ensures better stability of regenerated base oils and fluidize the impurities, which allows a easier operation of the process.
- the oil temperature is then advantageously between 270 and 310 ° C.
- the additional basic addition is carried out under the same concentration conditions and than in the first embodiment, but after the extraction operation of diesel (stripping).
- a base stored in a tank 18 is brought and mixed by means 19 with oil stripped reheated directed towards the column of splitting.
- an evaporator 13 preferably thin-film, coupled to a vacuum column 10 eliminates most of the impurities.
- the oil obtained is then subjected to oxidation accelerated in a bin 22, before a quantity complementary to pure bases is added to it.
- a base stored in a tank 23b is brought and mixed with the oil by means of mixture 24.
- the oil is then fractionated in the column of distillation 20.
- the oil temperature when adding the base is advantageously between 200 and 300 ° C. for injection from reservoir 23b just before column 20 and is between 120 and 200 ° C for addition from a tank 23a directly in the oxidation tank 22.
- the evaporator 13 is advantageously a thin film evaporator. It is also possible to use several evaporators successively.
- the residues 21 of column 20 are, according to the efficiency of this column and the requirements imposed regenerated oils, either recirculated and injected at the entry in column 10, either routed to the storage of residues such as residues 15 from the distillation column 10 and the evaporator 13.
- sample 2 was obtained by a process according to the invention implemented according to one of Figures 2 and 3.
- Sample 3 was obtained by a process according to the invention implemented according to Figure 4. These samples are compared to sample 1 obtained with a single basic injection according to the prior art.
- samples 5 and 6 obtained according to the invention are to be compared with sample 4 obtained according to the prior art.

Description
- l'adjonction complémentaire de bases fortes est réalisée au cours de l'étape d'extraction et de récupération de gasoil,
- l'adjonction complémentaire de bases fortes est réalisée postérieurement à l'étape d'extraction et de récupération de gasoil,
- après l'étape de déshydratation, d'extraction des hydrocarbures légers et du stripping du gasoil, l'huile strippée est débarrassée de ses impuretés (résidus) dans une colonne sous vide munie d'un système de rebouillage, puis soumise à une étape d'oxydation avant l'adjonction complémentaire de bases fortes, puis fractionnée,
- l'élimination des impuretés est obtenue par distillation sous vide assurant la séparation en huiles de bases lubrifiantes d'une part, et en un résidu concentrant toutes les impuretés d'autre part.
