Definitions
- the present invention relates to a process for refining crude oils with high organic acidity.
- Crude oils or fractions thereof having high acid contents are mainly those containing naphthenic acids. It is known that these crude oils present risks of corrosion both during their extraction from the oil field, during their transportation and during their refining. Oil tankers and refiners must find ways to recover these crude oils without being forced to develop new technologies to protect devices and equipment for transporting these crude oils or their fractions or for processing them. whether in the field, in shipping or rail, in pipes or in the refinery. This acidity of crude oils is conventionally measured by the number or index of TAN (Total Acid Number), which is measured in accordance with standard ASTM D664 by potentiometry and standard D974 by colorimetry. So, we apply a.
- TAN Total Acid Number
- US-P-2769768 describes the use of a linear or branched primary alcohol having from 4 to 7 carbon atoms with a mixture formed of methanol and ammonia to neutralize and remove heavy naphthenic acids from a hydrocarbon oil dewaxed.
- Patent US-3176041 proposes to trap the naphthenic acids of a crude oil by contact with a clay impregnated with a volatile amine having a boiling point below 100 ° C., in particular ammonia. This process is not applicable on the crude oil production field, nor even in a refinery because it requires a contact temperature above 200 ° C for 20 to 75 minutes and the extremely complex daily regeneration of several hundred tonnes of clay .
- US-P-2911360 describes a process applying to crude oil.
- the crude oil is deacidified in the liquid phase by contacting with a base in the presence of an alcohol, then distilled.
- the base can be ammonia, while the next phase is an aqueous solution containing 30 to 50% by weight of alcohol.
- the naphthenic acids recovered by distillation are regenerated after acidification with sulfuric acid of the extraction solvent. This process is cumbersome because it involves two treatments, one in the liquid phase and the other in the vapor phase. Furthermore, it is only applicable in a refinery, since it includes atmospheric distillation and vacuum distillation of the treated crude oil.
- US-P-4634519 describes a process for deacidifying petroleum fractions using a specific solvent mixture, comprising water, methanol and ammonia. It is a question here of extracting naphthenic acids. This process applies to petroleum fractions only, since the application of this treatment to crude oil has led to a stable emulsion making recovery of the extraction solvent almost impossible.
- the object of the present invention is to convert into amides, the organic acids contained in a crude oil with high acidity, mainly the acids naphthenic, during a conventional refining of this crude oil in a refinery.
- the distilled fractions thus neutralized are no longer the cause of major corrosion phenomena in the equipment crossed.
- these cuts can even be valued, this treatment having the effect of promoting the appearance of amide functions improving the quality of the products sold. It is thus possible to limit the addition of lubricating additives in gasolines and middle distillates, kerosene and diesel, this lubricating function being in fact already present within the distilled cut.
- the present invention therefore relates to a process for refining by neutralization of the organic acidity of crude oils with high acidity consisting in adding a nitrogenous compound to said crude oil, said process being characterized in that one introduces in at least one point of the petroleum pretreatment unit upstream of, or in the atmospheric distillation unit, a nitrogenous compound comprising at least three carbon atoms, a secondary amino group and a hydroxyl group.
- a nitrogenous compound comprising at least three carbon atoms, a secondary amino group and a hydroxyl group.
- the amine salts resulting from the naphthenic acids remain in the crude oil both during the crude oil preheating operations and during the desalting operations, gradually transforming into amides. Thus, they are always present but in the amide form in the crude oil when it enters the atmospheric distillation furnace.
- the amidified naphthenic acids and the other amides possibly formed from other acidic compounds present are distilled like the other hydrocarbons and are found in the various cuts usually distilled. It is advantageously found that these amides give the distilled cuts unexpected properties of lubricity and anticorrosion. Thus, it was thus found that at the head of the tower it was possible to limit or even eliminate the addition of neutralizing amines.
- cuts of middle distillates for the production of diesel have very low acidity and improved lubricity.
- the nitrogen compounds used are chosen from the compounds of formula (I) below: Y - OH
- IZ in which Y is a linear or branched alkyl group comprising from 1 to 10 carbon atoms, optionally hydroxylated, and Z is chosen from alkyl, hydroxyalkyl and polyhydroxyalkyl groups (containing up to 6, preferably up to 4 hydroxy), primary and secondary amines or tertiary and their hydroxylated and polyhydroxylated derivatives, the alkyl functions of these groups comprising from 1 to 10 carbon atoms.
- a compound of formula (I) in which Z is a group chosen from hydroxyalkyl and polyhydroxyalkyl groups are chosen from the dialkanolamines from the group consisting of diethanolamine, dipropanolamine, dibutanolamine, N-propanol-2-ethanolamine, N-butanol-2-ethanolamine, N - butanol-3-ethanolamine, N-butanol-2-propanolamine, N-butanol-3-propanolamine, N-propanol-2-butanolamine, di- (methyl1-hydroxy2) - propylamine, diisopropanolamine and di - (méthyl2hydroxy2) -butylamine.
- the preferred compounds are chosen from diethanolamine and diisopropanolamine.
- the compounds of formula (I) are chosen from N-methyl-ethanolamine, N-propyl-ethanoiamine, N-butylethanolamine, N-isobutylethanolamine, N-pentylethanolamine, N-methyl-propanolamine, N-isopentylethanolamine, N-propyl-propanolamine, N-butylpropanolamine, N-isobutylpropanolamine, N-pentylpropanolamine, N-isopentylpropanolamine, N-methyl-butanolamine, N-propyl-butanolamine, N-butylbutanolamine, N-isobutyl -butanolamine, N-pentylbutanolamine, N-isopentylbutanolamine, N-methyl-pentanolamine, N-propyl-pentanolamine, N-butylpentanolamine, N-isopentylbut
- the preferred compounds of this third mode are chosen from the group consisting of N-Hydroxy-2-ethylhydrazine, N-hydroxy-2-ethylethylenediamine, N-hydroxy-2-ethyl- (1-3) propylenediamine, N , N'-bis (2,3-dihydroxy-propyl) amine and hydroxy-2- (1, 3) propylenediamine.
- N-hydroxy-2-ethylethylenediamine will be chosen.
- the compound of formula (I) can be introduced before the crude oil desalination unit, in the preheating train of desalted crude oil, preferably before the exchangers or else in the distillation tower.
- Another object of the invention is the application of the process for the neutralization of organic acids contained in crude oils with an acidity greater than 0.5 mg KOH / g.
- a third object of the invention corresponds to the petroleum fractions obtained by application of said method according to the first object of the invention.
- a second type of cut corresponds to the so-called light cuts of cut temperature between the initial point and 150 ° C. and of acidity less than 0.5 mg of KOH / g.
- the present example describes the process for transforming organic acids in crude petroleum with the nitrogen compounds according to the invention.
- the purpose of the present example is to describe the advantages linked to the process with regard to the improvement of the lubricity of middle distillate cuts and the anticorrosion effect of the amides formed in light distillation cuts.
- Example I The 230-350 ° C sections of Example I are therefore taken up again with and without amidation before distillation and the lubricity is measured on each of them by the method known as HFRR (High Frequency Reciprocating Ring), according to standard EC12156-1. It is expressed in wear diameter (WSR: Wear Scare Diameter) in ⁇ m. Correct lubrication leads to wear diameter values of less than 460 ⁇ m. The lower this value, the better the lubricity.
- WSR Wear Scare Diameter
- the present example aims to show the progressive nature of the reaction of the alkanolamines in particular of diethanolamine (DEA) on crude oil B with an acidity corresponding to a TAN of 4.47 or 68 mmol / l of acidity measured.
- DEA diethanolamine
- reaction is followed within the crude oil during the addition of DEA by IRFT spectrometry using a measuring rod immersed in crude oil B forming part of the REACT IR spectrometer sold by the company METTLER.
- Figures 1 and 2 give a representation of the evolution of the infrared spectra during the addition of DEA and during heating as a function of time.
- Figure 1 shows, in three dimensions, the disappearance of the acid derivatives (band centered on the wavelength 1710 cm “1 ), the appearance of amine salts (band centered on 1560 cm “ 1 ) and the appearance amides (strip centered on 1650 cm “1 ).
- FIG. 2 represents, in two dimensions, as a function of time, the formation of amide (band centered on 650 cm ⁇ 1 ) after addition of DEA and the maintenance of crude oil B for one hour at 140 ° C.
- the formation of esters in small quantities linked to the presence of water supplied by the addition of DEA (band centered on 1740 cm ⁇ 1 ).
