Definitions
- the invention relates to a petroleum product and a process for obtaining said product.
- tanker which can possibly be used for the formulation of a motor fuel internal combustion and the product obtained by the process.
- the diesel that we find currently on the market either in the form of fuels for combustion engines internal compression ignition (diesel type), either as fuel, are most often refinery products that contain sulfur in one amount (expressed by weight of sulfur) of about 0.3%. They are usually obtained following a hydrodesulfurization treatment from a feed which can come from the direct distillation of crude oil or from a special treatment of a crude oil (e.g. pyrolysis or distillation followed by pyrolysis of the fraction recovered during distillation, or thermal or catalytic cracking) generally containing at least 0.8% by weight of sulfur.
- a hydrodesulfurization treatment from a feed which can come from the direct distillation of crude oil or from a special treatment of a crude oil (e.g. pyrolysis or distillation followed by pyrolysis of the fraction recovered during distillation, or
- sulfur content standards are in place. or will be implemented in the very near future. These standards are further more severe especially for diesel intended to be used as fuel for engines. Thus in France, in particular from 1995, the sulfur content of these gas oils must be at most 0.05% by weight (500 ppm) while diesel oils conforming to the standards in force have a sulfur content up to 0.3%.
- diesel oils used in France as fuel for engines with internal combustion must currently have a cetane number at least equal to 48 and gas oils used as fuel, a cetane number at least equal to 40.
- cetane number at least equal to 48
- gas oils used as fuel a cetane number at least equal to 40.
- the present invention therefore relates to a simple implementation method, consuming little hydrogen and being able to use installations already present in the refinery, in particular the existing industrial hydrodesulfurization units, which limits the investment necessary for its implementation. It improves the qualities of diesel produced and comply with future standards and in particular that concerning the sulfur content.
- the method of the invention further allows, as will be shown in the embodiment described below, to improve the cetane number diesel engine, to reduce its content of aromatic compounds not containing of sulfur heteroatom in their molecule, to reduce its content of nitrogenous compounds to improve its color and its odor and finally to reduce the formation of particles solids when used in an internal combustion engine.
- hydrodesulfurization instead of hydrotreatment.
- polyaromatic compounds compounds having at least two aromatic cycles, sulfur or not.
- the initial and final boiling point temperatures are TBP cut points.
- At least 50% is introduced. volume of the product (Q2) and preferably at least 90%, or even all of this product preferably in the hydrodesulfurization reactor, all of the overhead product T1 from the distillation.
- This achievement allows to obtain a quantity of petroleum product with a very low sulfur content. In other terms we thus obtain a greater quantity of a recoverable product entering the composition of a fuel for internal combustion engines.
- the hydrocarbon feedstock which is treated according to the process of the invention is the most often referred to as diesel fuel cut and preferably has an initial boiling point of 150 ° C and a final boiling point of 400 ° C, its sulfur content is usually more than 0.1% and most often more than 0.5% by weight, its aromatic content at least partly in the form of compounds polyaromatics is usually 15% to 70% by weight and its content of n- and iso-alkanes is 30 to 45% by weight.
- This charge is most often a diesel fuel direct distillation or pyrolysis diesel.
- the color of this charge measured according to the ASTM D 1500 method is usually greater than or equal to 2.
- the index of cetane according to ISO 5165, this charge is most often less than about 60 and it is for example from 50 to 55.
- the nitrogen content of this charge is usually 20 to 3000 ppm expressed by weight of nitrogen relative to the weight of load.
- the product (P) obtained by the process of the present invention usually has a nitrogen content expressed by weight of nitrogen usually 2 times less than that of the initial charge and often 4 to 5 times less.
- This product (P) most often has a color measured according to the Saybolt standard from 10 to 30, most often 15 to 25 and the cetane number of this product is generally at least 2 points higher and often at least 5 points at the cetane number of the initial charge (e.g. 2 to 10 points).
- the content of aromatic compounds containing no atom sulfur in their molecule in this product (P) is usually reduced by at least 10% by weight relative to that of the initial charge and often at least 30% in weight.
- the sulfur content compared to that of the initial charge is lower or equal to 5% by weight.
- the content of n-and iso-alkanes generally increases from 4 to 15 points and most often from 6 to 11 points compared to that of the initial charge.
- the invention advantageously relates to a petroleum product, which can be used in particular as a base for the composition of a fuel, characterized in that the distillation cut corresponds to 95% by weight distilled between 320 ° C and 460 ° C, its cetane number is greater than 60, its content of n- and iso-alkanes is at least equal to 48% by weight, its sulfur content less than or equal to 500 ppm (weight) and its nitrogen content less than 600 ppm, preferably 50 to 125 ppm.
- It also has a solvent content generally less than 10 ppm in weight, advantageously less than 5 ppm and most often less than 1 ppm.
- the distillation is carried out under conditions allowing a product of head (T1) containing only a small proportion of compounds with at least one atom of sulfur in their molecule very easily hydrotreated.
- the top product is usually a fraction whose final boiling point is less than 360 ° C, preferably less than 330 ° C and for example 310 ° C.
- the tail product (Q1) is usually a fraction with an initial boiling point above 300 ° C, often above 330 ° C and sometimes higher than 360 ° C, which eliminates sulfur compounds raffinate refractories that would require further pressure hydrotreatment high and therefore at a much higher cost.
- the liquid / liquid extraction step is a step carried out under conditions classics. This extraction could for example be carried out against the current in a conventional device, for example a filling column, trays or mechanical agitation (R.D.C.: rotating disc contactor) generally having from 1 to 20 theoretical stages and preferably 5 to 10 stages at a temperature generally between 0 ° C and 140 ° C, advantageously between 30 ° C and 80 ° C and under a pressure allowing to operate in the liquid phase and therefore between 0.1 and 1 MPa, preferably between 0.1 and 0.3 MPa.
- the volume ratio of the solvent (S1) the volume of the tail product (Q1) is generally 0.2: 1 to 5: 1, preferably from 0.5: 1 to 2: 1 and most often from 1: 1.
- the solvent is preferably chosen from the group of solvents making it possible to extract at least part of the compounds aromatic, not containing sulfur atom in their molecule, present in the product (Q1) obtained in step a).
- the extraction conditions are preferably chosen so as to obtain a raffinate (R1) containing by weight not more than 90% and preferably at most 70% by weight of the total weight of the aromatic compounds, do not containing no sulfur atom in their molecule, present in the product (Q1) obtained in step a).
- the extract (E1) under these conditions will contain at least 10% and often at least 30% by weight of the total weight of the aromatic compounds, containing no sulfur atom in their molecule, present in the product (Q1) obtained in step a).
- the extraction solvent is most often a single solvent, but it is also possible use solvent mixtures.
- This solvent generally contains less than 20% and often less than 10% by weight of water.
- This solvent can be an anhydrous solvent. he is most often chosen from the group formed by methanol, acetonitrile, monomethylformamide, dimethylformamide, dimethylacetamide, furfural, N-methylpyrolidone and dimethyl sulfoxide. We very often use the dimethylformamide, N-methylpyrolidone or furfural.
- At least one cosolvent which can be an alcohol of 1 to 6 carbon atoms, for example a linear or branched alcohol, or furfuryl alcohol.
- the feed to be treated has a high final boiling point and is particularly rich in nitrogen compounds, especially basic, it may be advantageous to introduce with the extraction solvent alone or as a mixture, a minor amount of acids, in particular carboxylic (less than 1% by weight relative to the solvent for example).
- carboxylic acids of 1 to 6 atoms of carbon and more particularly, acids having a boiling point below 250 ° C, in particular formic acid, acetic acid, propionic acid, butanoic acid, pentanoic acid, maleic acid, crotonic acid, acid isobutyric, valeric acid, trimethylacetic acid, benzoic acid, and acid 2-furoic.
- the raffinate (R1) obtained in step b) is then sent to a distillation zone for example, in which it is distilled under conditions to recover an overhead fraction enriched, and preferably highly enriched, in solvent (S1) and a product (Q2) preferably highly depleted in solvent (S1). Most often conditions of this distillation are chosen so as to obtain a fraction of the top containing almost all of the solvent, for example more than 95% by weight the quantity of solvent contained in the raffinate (R1) and introduced into this zone distillation. At least 99% by weight of the amount is thus preferably recovered. of solvent contained in the raffinate (R1).
- the raffinate can be sent in at least a separation flask where a liquid-vapor balance (flash) is achieved and obtains a product (S1) enriched in solvent and a product (Q2) depleted in solvent.
- This or these balloons can be followed by stripping, for example with steam or nitrogen to recover the last traces of solvent.
- the parameters of the hydrodesulfurization step generally chosen most often correspond to those of a hydrodesulfurization carried out under mild conditions.
- the spatial speed can be high, for example greater than 2 h -1 .
- the catalyst is one of those, for example, sold by the company PROCATALYSE.
- the extract (E1) obtained in step b) is then sent to a separation zone, for example a distillation in which it is distilled under conditions allowing to recover a fraction enriched, and preferably highly enriched, in solvent (S1) and a product (Q3) depleted in solvent (S1).
- a separation zone for example a distillation in which it is distilled under conditions allowing to recover a fraction enriched, and preferably highly enriched, in solvent (S1) and a product (Q3) depleted in solvent (S1).
- the conditions for this separation are chosen so as to obtain a product containing almost all of the solvent, that is to say for example more than 95% by weight of the amount of solvent contained in the extract (E1) and introduced into this separation zone.
- the product (Q3) is sent in a hydrodesulfurization zone in which it is subjected to a hydrodesulfurization, for example in the presence of a catalyst marketed by the PROCATALYSE under generally more severe conditions allowing to obtain a product (P ') having a sulfur content less than or equal to 0.3% by weight and preferably less than or equal to 0.2% by weight, or even less or equal 0.1% by weight.
- This product (P ') will of course not be usable as fuel for engines, since most often containing a quantity of sulfur higher than the future standard, however we can probably use it as combustible.
- At least part of the product (Q2) can be recovered at the end of step c) by lines (7) and (13) and be used as is combustible or be mixed with the product (P ') resulting from the hydrodesulfurization of product (Q3) or even be sent mixed with at least part of the product (Q3) in a hydrodesulfurization zone.
- an amount of product at least partially desulphurized, usable as fuel more important.

Description
- une étape a) de distillation, de préférence à la pression atmosphérique, dans laquelle on sépare en queue un produit (Q1) contenant la majorité des composés polyaromatiques et un produit de tête (T1),
- une étape b) d'extraction liquide/liquide dans laquelle on met en contact, à une température d'au plus 140°C, de préférence de 0 à 80°C, dans des conditions d'extraction des composés polyaromatiques, le produit de queue (Q1) obtenu à l'étape a) avec un solvant ou un mélange de solvants (S1) permettant d'extraire au moins en partie les composés polyaromatiques qu'il contient, ledit solvant ayant un point initial d'ébullition inférieur d'au moins 20 °C et de préférence inférieur d'au moins 50 °C au point initial d'ébullition du produit de queue (Q1) obtenu à l'étape a), et au cours de laquelle on récupère un extrait (E1) enrichi en composés polyaromatiques et un raffinat (R1),
- une étape c) de séparation, par exemple de distillation, de préférence à la pression atmosphérique, du raffinat (R1) obtenu à l'étape b) dans laquelle on sépare un produit enrichi en solvant (S1) d'un produit (Q2) appauvri en solvant (S1),
- une étape d) d'hydrotraitement dans laquelle on introduit dans un réacteur d'hydrotraitement une partie au moins du produit de tête (T1) obtenu à l'étape a) et une partie au moins du produit (Q2) obtenu à l'étape c), puis on effectue l'hydrodésulfuration du mélange obtenu, sous une pression partielle d'hydrogène généralement inférieure à 10 mégapascals (MPa), avantageusement inférieure à 5 MPa et de préférence de 1,5 à 3,5 MPa, et on récupère un produit (P) ayant des qualités améliorées et contenant moins de 500 ppm en poids de soufre, par exemple 100 à 480 ppm.
Le catalyseur est l'un de ceux par exemple, commercialisés par la société PROCATALYSE.
Il présente, par ailleurs, les principaux avantages suivants : on obtient dans le raffinat (tableau) une teneur en n- et iso-alcanes plus élevée que selon les procédés d'hydrocraquage ou d'hydrodésaromatisation, un indice de cétane plus élevé, en dépit d'une teneur en hydrocarbures aromatiques supérieure à 10%. Par ailleurs, la consommation en hydrogène dans l'hydrotraitement est moindre. Elle peut être réduite par exemple à 0,15% poids par rapport à la charge, lorsque l'hydrogénation est limitée au maximum.
