Definitions
- the present invention relates to the field of odorants for gaseous fuels, in particular odorless, and more particularly to a composition comprising at least one alkyl sulfide and at least two alkyl acrylates for gas leak detection and prevention. the risks of explosion that result.
- gaseous fuels used today whether natural gas, propane, butane, liquefied petroleum gas (or LPG), or even oxygen (for example for welds), are essentially odorless, either because of their origin or because of the purification treatment they received.
- LPG liquefied petroleum gas
- oxygen for example for welds
- Natural gas is generally sent odorless to the consuming countries from the production sites, after an appropriate purification treatment, either by gas pipeline or (in a liquid state) in specialized vessels (LNG carriers).
- LNG carriers specialized vessels
- natural gas is thus received in a limited number of injection stations where the odorant is injected so that natural gas as well as that which circulates in the French network of gas pipeline, than that which is stored in underground tanks is odorised, which allows easy detection in case of leakage, regardless of the portion of the network where it occurs.
- natural gas can be distributed on the territory by a network of gas pipelines in which it circulates without odorant, which is then odorized at the entrance of the cities where it is consumed, which requires a number even higher injection stations.
- the storage bins are most often maintained under nitrogen or natural gas in order to limit, at this stage, the risk of explosion.
- Alkyl sulfides are known as odorants, alone or in admixture. There may be mentioned, for example, diethylsulfide, dimethylsulfide, methylethylsulfide or tetrahydrothiophene which are widely used for their excellent properties, in particular, capable of triggering an alarming sensation in persons in the event of accidental leakage of the natural gas thus smelled, and initiate the necessary backup operations.
- these products generate a quantity of sulfur dioxide which, however small, becomes significant when an overall assessment is carried out at the level of a country or a region, especially at a rate of industrialization or high urbanization.
- the combustion of a natural gas odorised with tetrahydrothiophene at a concentration of 10 mg / Nm 3 (or number of m 3 of the gas, measured under normal conditions of temperature and pressure) generates 7 3 mg / Nm 3 of sulfur dioxide.
- alkyl acrylates as components of odorizing mixtures of gases is furthermore described in the literature.
- the application DE 19837066 mentions a process for odorizing natural gas by adding a mixture comprising an alkyl acrylate, a nitrogen compound of the pyrazine type, and an antioxidant.
- this mixture has the disadvantage of not having a characteristic odor of gas and is therefore likely to be confusing in the event of gas leakage. The risk is of course the non-detection of this leak and explosion, if the concentration of gas in the air reaches its lower explosive limit.
- Patent JP55-137190 also discloses an odorant mixture associating with ethyl acrylate a specific sulfur compound, in this case tert-butyl mercaptan (or TBM).
- TBM tert-butyl mercaptan
- the major drawback of this mixture is, however, that due to the chemical reactivity of the TBM with ethyl acrylate, the 2 components of the odorant mixture must, in the different injection stations, be stored in separate tanks and require also pumps and separate injection heads, for introduction into the pipeline.
- TBM tert-butyl mercaptan
- an odorant consisting of four components including an alkyl acrylate, an alkyl sulfide and an antioxidant stabilizing agent such as tert-butylhydroxytoluene, hydroquinone, etc.
- the object of the present invention is to propose a new odorant mixture, in particular overcoming the disadvantages of the odorizing mixtures of the prior art described above.
- composition that can be used especially as odorant of a gaseous fuel, more particularly natural gas, comprising:
- alkyl radical comprising from 1 to 4 carbon atoms
- R 1 and R 2 taken together with the sulfur atom to which they are attached represent a saturated or unsaturated ring comprising from 3 to 5 carbon atoms, optionally substituted by an alkyl radical Ci-C4 or Ci-C 4 alkenyl;
- alkyl (II) acrylates from 50 to 99.8 parts by weight of at least two alkyl (II) acrylates, the alkyl radical of which comprises from 1 to 12 carbon atoms, preferably from 1 to 8;
- - - RR 33 eett R 4 identical or different, each represent a tertiary or secondary hydrocarbon radical comprising from 2 to 30 carbon atoms, preferably from 4 to 15, and optionally one or more heteroatoms selected from sulfur, phosphorus, nitrogen or oxygen; or
- R 3 and R 4 taken with the nitrogen atom to which they are attached represent a cyclic hydrocarbon radical comprising from 4 to 10 carbon atoms, preferably from 4 to 6, said radical being optionally substituted.
- the composition according to the invention gives the gaseous fuels, in particular natural gas after it has been injected into it, a high odor power, comparable to that obtained with the alkyl sulfide odorants of the prior art, allowing any person in the vicinity of a leak to recognize it, and to take appropriate safety measures.
- This strong odor power is obtained at the same time as a significant decrease in the amounts of SO 2 released into the ecosphere after combustion of the gas thus odorized.
- this composition because of the lack of reactivity between the compounds (I) and (II) can be implemented in the injection stations by means of a single storage tank, a single pump and 'a single injection head, which leads to greatly simplified logistics.
- composition according to the invention comprises from 5 to 14.95 parts by weight of compound (s) (I), from 85 to 94.95 parts by weight of compounds (II) and from 0.005 to 0.05 parts by weight of compound (s) (III).
- alkyl sulfide (s) (I) tetrahydrothiophene (THT), methyl ethyl sulfide (MES), dimethyl sulfide (DMS) and / or diethyl sulfide (DES).
- TTT tetrahydrothiophene
- MES methyl ethyl sulfide
- DMS dimethyl sulfide
- DES diethyl sulfide
- the acrylic acid esters (II) are chosen in particular from methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl and pentyl acrylates. hexyl, heptyl, octyl and dodecyl.
- a combination of alkyl acrylates containing in particular ethyl acrylate and advantageously a combination of alkyl acrylates containing in particular acrylate is used.
- methyl and ethyl acrylate Preferred combinations of alkyl acrylates containing especially methyl acrylate and ethyl acrylate generally comprise 20 to 40 parts by weight of methyl acrylate per 100 parts by weight of total methyl acrylate + acrylate ethyl.
- a composition comprising tetrahydrothiophene, methyl acrylate and ethyl acrylate is used.
- composition according to the invention of compound (s) (III) has the effect of inhibiting the polymerization of acrylates which are very reactive monomers that can polymerize spontaneously.
- uncontrolled polymerization is likely to put people in the vicinity of injection stations, such as residents or workers in charge of maintenance in danger, because of a risk of explosion.
- This polymerization occurring during storage, including for example in the bins or storage tanks of the injection stations, can also lead to fouling or even a quick clogging of the pipes between the storage tank and the injection point.
- Such a phenomenon can lead to an uncontrolled decline in the concentration of odorant in natural gas, which increases the risk of undetected gas leakage.
- the inhibitors of formula (IV) have the advantage, unlike other inhibitors such as free radical inhibitors belonging to the family of hydroquinones, not requiring storage of the odorant mixture in air. Storage under air is indeed necessary for hydroquinone free radical inhibitors, because the active form of the inhibitor is a molecule comprising a radical which is formed as a result of a reaction with oxygen.
- the active form of the inhibitor is a molecule comprising a radical which is formed as a result of a reaction with oxygen.
- the inhibitors of formula (IV) also offer the advantage, for the same reason, of being able to be used in nitrogen storage tanks that are encountered in certain natural gas injection stations.
- the compound used as an inhibitor of formula (IV) is a compound derived from tetramethylpiperidine oxide (also known as TEMPO) of formula (IVa):
- R 5 is hydroxy, amino, R 6 COO-, R 6 CONH-, wherein R 6 is a C 1 -C 4 alkyl radical.
- the present invention also relates to a process for odorizing an odorless gaseous fuel comprising the addition of an effective amount of the composition comprising at least one alkyl sulphide, at least two alkyl acrylates, and at least one a stable alkyl acrylate polymerization inhibitor compound (III) in the presence and absence of oxygen, preferably of formula (IV).
- the amount of said composition can be determined by those skilled in the art through systematic tests, taking into account the particular characteristics of the gaseous fuel, and distribution networks. As a guide only, this effective amount may be between 1 and 500 mg / Nm 3 , preferably between 2 and 50 mg / Nm 3 .
- composition according to the invention described above can be used as it is or be diluted in a solvent or a mixture of solvents inert with respect to the acrylates.
- solvents mention may be made of cyclohexane and n-hexane.
- the dilution of the composition can reach 85%, ie 15 parts by weight of the composition according to the invention are diluted in 85 parts by weight of solvent.
- the gaseous fuels to which the process according to the invention applies include: natural gas propane, butane, liquefied petroleum gas (or LPG), or even oxygen or hydrogen, such as that generated by fuel cells.
- Natural gas is a preferred gaseous fuel according to the present invention because of its very wide distribution and the importance of distribution networks, making it particularly desirable to reduce any danger resulting for example from a leak.
- composition that can be used as odorant is added by injection to the specialized stations according to the usual techniques used in this field.
- the subject of the invention is a gaseous fuel, preferably a natural gas, comprising an amount of between 1 and 500 mg / Nm 3 , preferably between 2 and 50 mg / Nm 3 of the composition comprising at least one sulphide of alkyl, at least two alkyl acrylates, and at least one compound (III), preferably of formula (IV),
- Example 1 Odorization of natural gas with tetrahydrothiophene 10 mg per Nm 3 of tetrahydrothiophene are injected into natural gas by means of a suitable laboratory device.
- EXAMPLE 2 The following composition is obtained by simply mixing the weight of the components indicated in the liquid state, with the exception of the Hydroxy TEMPO which is a solid:
- Example 1 is then repeated, replacing the tetrahydrothiophene with the composition according to the invention thus prepared.
- the gas thus odorized is subjected to an olfactory test, from which it emerges that the gas thus odorized has a good alerting power (strong odorous power similar to that of the composition of Example 1)
- the sulfur dioxide content formed, after combustion of the gas thus odorized, is equal to 0.87 mg / Nm 3 .
- composition is obtained by simply mixing the weight of the components indicated in the liquid state:
