Definitions
- the present invention relates to a dechlorination process a fraction of used oil.
- the present invention therefore aims to reduce the content of used oils chlorine at a rate compatible with recycling operations in refinery of these oils and she proposes, for this purpose, to use composite products solids, capable of fixing chlorinated ions, already known in the technical for other applications and under conditions different use.
- chlorine traps based on alumina or metal oxides or metal hydroxides such as CaO, Na 2 O, K 2 O, MgO, as well as the corresponding hydroxides, for eliminating the chlorine present in the liquid or gaseous flows of process units, in particular in reforming or isomerization units.
- compositions generally have a dimension particles of the order of 0.5 to 3 mm and they neutralize usually chlorine by adsorption. They are generally used at room temperature or order, at most 100 ° C and atmospheric pressure, and they usually retain about 15% of the chlorine present in the charges processed.
- the Applicant has established that such chlorine traps are particularly well suited for an operation of partial dechlorination of used oils, upstream of any recycling operation in a refinery, in particular a vacuum distillation, and that, unexpectedly, their chlorine binding power increases significantly with the temperature of the treated oils, the chlorine trap can retain at least 40% of the chlorine present in the treated oil at a temperature between 300 and 400 ° C and at pressure atmospheric.
- this amount of chlorine greater than 40% represents roughly the fraction of chlorine compounds that break down in a used oil recycling operation or which distill in a fractionation column under used oil vacuum, leading to acid formation hydrochloric, and the invention therefore proposes, in a simple manner, subjecting used oil to dechlorination upstream of any recycling operation.
- the invention therefore relates to a method of dechlorination of a fraction of used lubricating oil, possibly mixed with another charge hydrocarbon, this process being characterized in that, in upstream of an oil refinery recycling operation used, the used oil is subjected to a dechlorination operation at least partial by passing over a bed of particles of an adsorption neutralizing composition containing, as active compound capable of fixing chlorine at least one oxide of a metal belonging to groups I and II of the Periodic classification and / or at least one hydroxide of a metal belonging to groups I and II of the Classification Periodic.
- the active compound of the composition neutralizing will be an oxide of calcium, magnesium, sodium or potassium, or a calcium hydroxide, magnesium, sodium or potassium.
- Calcium oxide and calcium hydroxide are active compounds even more preferred.
- the dechlorination phase will be carried out under conditions such that at least 40% and, preferably, 60% of the amount of chlorine present in the used oil is retained by the neutralizing composition by adsorption.
- These conditions are, for example, the following: a temperature of at least 150 ° C and, preferably, of the order of 400 ° C, an hourly space velocity of the used oil of 0.5 h -1 ( volume of used oil, per volume of adsorbent and per hour) and a pressure substantially equal to atmospheric pressure.
- the used oil prior to the dechlorination operation, the used oil will be subjected to a distillation phase atmospheric at a temperature of 300 to 400 ° C in sight to remove the water and the light solvents it contains, and the dechlorination operation will be carried out on the used oil from this atmospheric distillation, possibly after reheating of this oil, by example by heat exchange, to increase the efficiency of dechlorination.
- the used oil thus dechlorinated can then be subjected, for example, to vacuum distillation, preferably mixed with another filler, such as residue from atmospheric distillation, with a view to separating into particular vacuum diesel, vacuum distillate and a bituminous vacuum residue, without forming, as it is usual at this stage, hydrochloric acid responsible marked corrosion in the installations.
- vacuum distillation preferably mixed with another filler, such as residue from atmospheric distillation, with a view to separating into particular vacuum diesel, vacuum distillate and a bituminous vacuum residue, without forming, as it is usual at this stage, hydrochloric acid responsible marked corrosion in the installations.
- compositions of dechlorination used in the process of the invention are well known in the art and generally contain at least 25% by weight of active compound. They are marketed, for example, under the names TRAP'IT sales by Catalysts and Chemicals Europe, SELEXSORB HCl by ALCOA, and DISCOVERY ALUMINAS by the Dycat International Company.
- the preferred composition for the implementation of the invention is that marketed under the name TRAP'IT, which contains, in% by weight, from 23.0 to 27.0% of CaO, constituting the active product, and from 43 to 53.0% of oxide of zinc, serving as a support, the complement to 100% being consisting of a binder.
- TRAP'IT which contains, in% by weight, from 23.0 to 27.0% of CaO, constituting the active product, and from 43 to 53.0% of oxide of zinc, serving as a support, the complement to 100% being consisting of a binder.
- This composition has, in general, an apparent specific mass of 0.720 to 0.800 cm 3 / g, a pore volume of 0.35 to 0.45 cm 3 / g and a specific surface of at least 22 m 2 / g. It is usually in the form of rods with a diameter of 1.2 to 1.8 mm and a length of about 4.0 to 12.0 mm.
- the used oil to be treated arriving via the line 1, is first topped, by atmospheric distillation, in a column 2.
- the water present in the used oil (4 to 10% by weight) is discharged at the top of the column via line 3, while the light solvents are evacuated via line 4.
- the chlorine trap contained in the tank 6 retains about 60% of the chlorine present in the oil used, and the treated oil, which contains only about 200 ppm of chlorine, is evacuated by a line 8 towards a vacuum distillation column 9, in which it is introduced, for example, with a residue of atmospheric distillation arriving via line 10.
- the chlorine content of the treated oil is compatible with the conditions of vacuum distillation, which is takes place without any particular risk of corrosion due to formation of hydrochloric acid in column 9.
- Example 1 which follows relates to an application of the method according to the invention using the device of the figure 1, it being understood that other forms of implementation are within the scope of the invention.
- Example 2 illustrates improved dechlorination of treated oil as the treatment temperature rises dechlorination.
- TRAP'IT registered trademark
- the oil leaving balloon 6 via line 8 does not contain more than 123 ppm by weight of chlorine and 62% of the chlorine present in the oil at the inlet of balloon 6 have therefore been fixed and retained by the TRAP'IT composition.
- composition of TRAP'IT can be scrapped or regenerated.
- This example aims to show the interest of driving the dechlorination operation at such a high temperature as possible.
- a head of used oil containing 325 ppm of chlorine is treated in a flask containing 15m3 of the TRAP'IT composition, at an hourly space speed of 0.5 h -1 .
- the treatment is carried out at various temperatures and the dechlorination rate is measured each time, that is to say the fraction, expressed in%, of chlorine of the charge retained by the dechlorination composition.
- the composition of DYCAT 115, in% by weight, is given in Table II below.
- the DYCAT 115 is in the form of spheres of approximately 3 to 5 mm in diameter.
