Definitions
- the present invention relates to a method of adding a malodorant to a consumer gas which is distributed to a consumer station, so that persons present in the surroundings of the distribution system will be warned that the surroun ⁇ ding atmosphere contains more than the lowest permitted concentration of gas, therewith constituting the risk of explosion, suffocation, toxicity or some other risk.
- gases which can be odorized in this way is oxygen, which can cause extremely comprehensive fire and explosion damage if it leaks into the surroundings ambient of the distribution system and/or the consumer station and therewith enriches the ambient air or atmosphere.
- Another example includes combustible gases, such as natural gas, propane gas, town gas, etc., which when admixed with atmospheric oxygen can give rise to fires and explosions.
- Another example includes odorless, toxic gases or more or less inert gases. If these latter gases escape into the ambient surrounds, they are able to displace the oxygen in the air, thereby creating suffocation conditions.
- the Finnish Patent Application No. 870146 describes an improved method of adding a malodorant to oxygen gas so that if the air becomes enriched with oxygen, individuals in the near vicinity are warned that there is an imminent risk of explosion.
- This improved method eliminates the need of han ⁇ dling toxic malodorants by the consumer, thereby avoiding the risk of explosion created by the addition of such malodor ⁇ ants.
- a gaseous mixture of malodorant and a carrier gas in this case oxygen, a so-called master gas, by adding to the oxygen gas a malodorant in a concentration of 1,000- 10,000 ppm.
- the master gas is admixed with oxygen gas distributed to the consumer in an amount such that the malodorant has a concentration of 5-50 ppm in the consumer gas.
- the master gas contains solely oxygen and malodorant, for example dimethyl sulphide, DMS
- DMS dimethyl sulphide
- this application teaches a method of producing a master gas consisting of 0 oxygen and a malodorant, in this case dimethyl sulphide.
- the master gas container is first filled with a mixture of dimethyl sulphide and nitrogen or helium gas.
- the dimethyl sulphide is present in a concentration of 0.5-2.5 mole per cent.
- Oxygen gas is then 5 introduced until a desired working pressure, e.g. 200 bars, is obtained in the container.
- the object of the present invention is to provide a 0 method for producing master gas for admixture with a consumer gas, preferably natural gas and other combustible gases, such as town gas and propane gas, and oxygen, and which avoids the aforesaid drawbacks.
- a consumer gas preferably natural gas and other combustible gases, such as town gas and propane gas, and oxygen
- the method is characterized by dissolving a malodorant 5 in the form of an organic sulphur compound or a mixture of two or more organic sulphur compounds, said compounds comprising tetrahydrothiophene, methyl mercaptan, ethyl mercaptan, propyl mercaptan, butyl mercaptan, dimethyl sulphide, diethyl sulphide and methylethyl sulphide, in condensed carbon dioxide, sulphur hexafluoride or dinitrogen oxide in a pressure vessel, thereby obtaining in the pressure vessel a liquid phase, consisting of a solution of the malodorant in the condensed gas, and a gas phase; and by removing the liquid phase from the vessel, vaporizing said liquid phase and adding the vapor phase to the consumer gas distributed to the consumer.
- a malodorant 5 in the form of an organic sulphur compound or a mixture of two or more organic sulphur compounds, said
- the malodorant has a concentration of 0.5-10 mole per cent in the master gas. It is also preferred to add the master gas to the consumer gas in a quantity such that the malodorant concentration in said consumer gas is 1-20 ppm.
- the invention also relates to a gaseous mixture con ⁇ sisting of liquid carbon dioxide, sulphur hexafluoride or dinitrogen oxide containing a dissolved malodorant of the aforesaid kind.
- the malodorant which is an ill-smelling organic com- pound or a mixture of two or more such compounds, is intro ⁇ pokerd into the carrier gas, i.e. the condensed gas, as nitrous gas (laughing gas) , sulphur hexafluoride or prefera ⁇ bly carbon dioxide, in an amount of 0.5-10 mole per cent, calculated on the total quantity of gas.
- the carrier gas i.e. the condensed gas, as nitrous gas (laughing gas) , sulphur hexafluoride or prefera ⁇ bly carbon dioxide
- the aforesaid ill- smelling substances are soluble in the condensed gases in quantities suf ⁇ ficient to enable the method to be applied in practice.
- the pressure in the resultant gas phase will vary when the gas mixture is stored at differing temperatures.
- the malodorant content of the condensed gas is only affected to a negligible extent at temperatures within the range of -40°C to +50°C.
- Admixture of the master gas i.e.
- the carrier gas diluted with the malodorant, with the consumer gas is effected by first removing the liquid mixture of carrier gas and malodorant from the pressure vessel in which the mixture is stored, and vaporizing the liquid phase and then introduc- ing the gaseous mixture into the consumer gas in quantities such that the concentration of malodorant in the consumer gas will lie within the range of 1-50 ppm (1.0001-0.0050 mole per cent) , preferably within the range of 1-20 ppm.
- the master gas i.e.
- the gas mixture consisting of malodorant and carrier gas is to be admixed with a consumer gas which is distributed to various consumer stations through a pipe network or a through a central gas system, a gas mixer of more or less conventional kind is connected to the system upstream of the inlet to the pipe network.
- the consumer gas and the master gas are mixed in desired proportions in this mixer.
- the gas mixer includes a control system by means of which the ratio between the flow of master gas and the flow of consumer gas can be constantly maintained at a constant level. For example, if the master gas contains 2 mole per -cent malodorant and the consumer gas shall contain 4 ppm malodorant, the aforesaid ratio shall be 1:5000.
- the vaporized mixture When the consumer gas is distributed to the consumer in a high pressure container, the vaporized mixture, the master gas, is first introduced into the container in a quantity such that the desired proportion of malodorant is obtained when subsequently introducing the consumer gas into the container to the desired container pressure.
- the consumer gas containing the malodorant added thereto in accordance with the invention will therefore contain a given amount of carrier gas in addition to the malodorant.
- the carrier-gas content of the master gas is, for instance, 95 mole per cent, i.e. the master gas contains 5 mole per cent malodorant, an admixture has been effected with one part of master gas to 5000 parts of consumer gas, the malodorant content will be 10 ppm and the carrier gas content, e.g. carbon dioxide, will be 0.02 mole per cent.
- This proportion of non-combustible carrier gas is insig ⁇ nificant with regard to combustible gases.
Abstract
Cette invention concerne un procédé d'adjonction d'une substance malodorante dans un gaz utilisé par des consommateurs, tel que de l'oxygène, du gaz naturel, du gaz propane, du gaz de ville ou tout autre gaz combustible, qui n'a pas d'odeur et qui est toxique, ou bien à un gaz plus ou moins inerte alimentant un point de consommation. L'adjonction de cette substance malodorante permet d'avertir les personnes se trouvant à proximité du point de consommation qu'il existe un risque d'incendie, d'explosion, d'asphyxie, de toxicité ou un autre risque lié à la présence d'un gaz de consommation dans l'atmosphère environnante, et ce, en raison d'une fuite, d'une négligence ou pour toute autre raison. Ce procédé comprend le mélange d'un gaz principal, par exemple, un gaz porteur dilué avec la substance malodorante, avec le gaz de consommation. Le trait caractéristique de ce procédé réside dans la dissolution de la substance molodorante qui se présente sous forme d'un composé de soufre organique ou d'un mélange de deux ou plusieurs composés de soufre organique, ces composés comprenant du tétrahydrothiophène, du mercaptan de méthyle, du mercaptan d'éthyle, du mercaptan de propyle et du mercaptan de butyle, du sulfure de diméthyle, du sulfure de diéthyle et du sulfure de méthyléthyle, dans du dioxyde de carbone condensé, de l'hexafluorure de soufre ou de l'oxyde nitreux dans un récipient de pression, qui produisent dans ce dernier une phase liquide, constituée d'une solution de substance malodorante dans le gaz condensé, et une phase gazeuse; on élimine ensuite la phase liquide du récipient, par vaporisation, et on ajoute la phase vapeur résultante dans le gaz de consommation, qui est alors distribué aux consommateurs. Cette invention concerne également un mélange gazeux comprenant la substance malodorante sous forme de dioxyde de carbone, d'hexafluorure de soufre ou d'oxyde nitreux condensés.This invention relates to a method of adding a smelly substance to a gas used by consumers, such as oxygen, natural gas, propane gas, town gas or any other combustible gas, which has no no smell and which is toxic, or to a more or less inert gas supplying a point of consumption. The addition of this smelly substance warns people near the point of consumption that there is a risk of fire, explosion, asphyxiation, toxicity or another risk related to the presence of 'a consumer gas in the surrounding atmosphere due to leakage, neglect or for any other reason. This process involves mixing a main gas, for example, a carrier gas diluted with the smelly substance, with the consumer gas. The characteristic feature of this process lies in the dissolution of the odoriferous substance which is in the form of an organic sulfur compound or of a mixture of two or more organic sulfur compounds, these compounds comprising tetrahydrothiophene, methyl mercaptan , ethyl mercaptan, propyl mercaptan and butyl mercaptan, dimethyl sulfide, diethyl sulfide and methylethyl sulfide, in condensed carbon dioxide, sulfur hexafluoride or oxide nitrous in a pressure vessel, which produce in the latter a liquid phase, consisting of a solution of smelly substance in the condensed gas, and a gas phase; the liquid phase is then removed from the container, by vaporization, and the resulting vapor phase is added to the consumption gas, which is then distributed to consumers. The invention also relates to a gas mixture comprising the smelly substance in the form of carbon dioxide, sulfur hexafluoride or condensed nitrous oxide.
