Abstract

Odorization of fuel medium particularly cryogenic medium has a fuel medium (7), which is stored in liquid, gaseous and/or in hydride form. The storage of the odorization medium requires at least one accumulator (1) and/or at least one fuel medium leading line (2,3), which is connected or connectable.

Description

Die Erfindung betrifft eine Anordnung zur Odorierung eines Kraftstoffmediums, vorzugsweise eines kryogenen Mediums, in einem Fahrzeug, wobei das Kraftstoffmedium in flüssiger und/oder gasförmiger Form und/oder in einem Hydridspeicher gespeichert ist.The Invention relates to an arrangement for odorizing a fuel medium, Preferably, a cryogenic medium, in a vehicle, wherein the Fuel medium in liquid and / or gaseous Form and / or stored in a hydride storage.

Im Folgenden werden bei den Bezeichnungen spezieller kryogener Medien entsprechend ihrem Aggregatzustand die Buchstaben "G" für "gasförmig" und "L" für "flüssig" bzw. "liquid" vorangestellt; also z. B. GH2 bzw. LH2 für gasförmigen bzw. flüssigen Wasserstoff.In the following, the designations of special cryogenic media are preceded by the letters "G" for "gaseous" and "L" for "liquid" or "liquid" according to their state of aggregation; So z. B. GH 2 or LH 2 for gaseous or liquid hydrogen.

Insbesondere Wasserstoff gewinnt gegenwärtig durch den steigenden Energiebedarf und das gestiegene Umweltbewusstsein als Energieträger bzw. Kraftstoffmedium zunehmend an Bedeutung. So werden bereits Lastkraftwagen, Busse, Personenkraftwagen sowie Schiffe mittels mit Wasserstoff-betriebenen Motoren bzw. Brennstoffzellen angetrieben.Especially Hydrogen is currently gaining due to the increasing energy demand and the increased environmental awareness as an energy source or Fuel medium increasingly important. So already trucks, Buses, passenger cars and ships by means of hydrogen-powered Motors or fuel cells driven.

Unter dem vorgenannten sowie nachfolgend verwendeten Begriff "Fahrzeug" seien alle Arten von Land-, Wasser- sowie Luftfahrzeugen zu verstehen, die einen Verbrennungsmotor und/oder eine Brennstoffzelle aufweisen.Under the aforementioned and subsequently used term "vehicle" are all types of land, water and air vehicles to understand one Combustion engine and / or have a fuel cell.

Die Speicherung von alternativen Kraftstoffen, wie beispielsweise Wasserstoff, in Fahrzeugen kann hierbei prinzipiell auf unterschiedliche Arten erfolgen; beispielhaft genannt seien:

  • – Speicherung in gasförmiger Form, wobei bisher Speicherdrücke von bis zu 1000 bar realisiert werden
  • – Speicherung in flüssiger Form in doppelwandigen, superisolierten Speicherbehältern
  • – Speicherung in gasförmiger Form unter niedrigem Druck in Metallhydriden mit niedriger Desorptionstemperatur
  • – Speicherung in sonstigen Speichersystemen die durch zuvor zugesetzte Odorierungsmedien bzw. Odoriermittel geschädigt bzw. vergiftet würden
The storage of alternative fuels, such as hydrogen, in vehicles can be done in principle in different ways; may be mentioned by way of example:
  • - Storage in gaseous form, which previously been realized storage pressures of up to 1000 bar
  • - Storage in liquid form in double-walled, super-insulated storage tanks
  • - Storage in gaseous form under low pressure in metal hydrides with low desorption temperature
  • - Storage in other storage systems that would be damaged or poisoned by previously added Odorierungsmedien or odorants

Aus Sicherheitsgründen ist es oftmals erwünscht, wenn bestimmten Medien, die unter gewissen Umständen zu einer Gefährdung von Menschen führen können, odoriert werden. Dadurch wird erreicht, dass diese Medien bei einem Entweichen bzw. Austreten aus Speichern und/oder Leitungen aufgrund des Geruches des zugesetzten Odorierungsmittels durch den Menschen erkannt und entsprechende (Gegen)Maßnahmen in die Wege geleitet werden können.Out security it is often desirable if certain media, which under certain circumstances endanger Lead people can, to be odorized. This ensures that these media at a Escape or escape from storage and / or lines due to the odor of the added odorant by humans detected and appropriate (counter) measures are initiated can.

Insbesondere Wasserstoff wird nach wie vor von einer Vielzahl von Menschen – insbesondere in Kombination mit Sauerstoff – als bedrohend empfunden. Da Wasserstoff geruchlos ist, ist eine Detektion über seinen Geruch für den Menschen nicht möglich. Um die Akzeptanz von Wasserstoff zu erhöhen ist es daher erstrebenswert, wenn sichergestellt werden könnte, dass Wasserstoff – gleiches gilt selbstverständlich auch für andere Medien – für den Menschen über den Geruch erkennbar ist.Especially Hydrogen is still used by a variety of people - especially in combination with oxygen - as felt threatening. Since hydrogen is odorless, detection is about it Smell for not possible for humans. Around It is therefore desirable to increase the acceptance of hydrogen if it could be ensured that hydrogen is the same of course also for other media - for the people about the Odor is recognizable.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Anordnung anzugeben, die dies auf einfache Art und Weise ermöglicht.task The present invention is a generic arrangement which makes this possible in a simple way.

Die erfindungsgemäße Anordnung zur Odorierung eines Kraftstoffmediums ist dadurch gekennzeichnet, dass wenigstens ein Speicherbehälter für das Odorierungsmedium vorgesehen und dieser mit dem Speicher des Kraftstoffmediums und/oder wenigstens einer das Kraftstoffmedium führenden Leitung verbunden oder verbindbar ist.The inventive arrangement for odorizing a fuel medium is characterized that at least one storage container for the Odorierungsmedium provided and this with the memory of the fuel medium and / or at least one line leading to the fuel medium or is connectable.

Erfindungsgemäß wird dem Kraftstoffmedium nunmehr ein Odorierungsmedium zugesetzt, so dass bei einem Austritt des Kraftstoffmediums dieses über den Geruch des zugesetzten Odorierungsmediums für den Menschen erkennbar bzw. detektierbar ist.According to the invention is the Fuel medium now added an odorization medium, so that at a leakage of the fuel medium this on the smell of the added Odorierungsmediums for recognizable or detectable to humans.

In Abgängigkeit von dem gewählten Odorierungsmedium sind oftmals bereits kleine Mengen ausreichend, dass eine sichere Detektion für den Menschen möglich ist.In Abgängigkeit from the chosen one Odorierungsmedium are often already small quantities sufficient that safe detection for possible for humans is.

Die erfindungsgemäße Anordnung weiterbildend wird daher vorgeschlagen, dass eine Dosiervorrichtung für das Odorierungsmedium vorgesehen ist.The inventive arrangement Further education is therefore proposed that a metering device for the Odorierungsmedium is provided.

Als Odorierungsmedium kommen vorzugsweise Geruchsstoffe bzw. Medien in Frage, die schon bei geringen Konzentrationen durch den Menschen wahrgenommen werden können.When Odorierungsmedium come preferably odors or media in question, even at low concentrations perceived by humans can be.

Hierbei ist jedoch darauf zu achten, dass das bzw. die gewählten Odorierungsmedien den Verbrennungsmotor bzw. die Brennstoffzelle nicht schädigen.in this connection however, make sure that the selected odorization media (s) Do not damage the combustion engine or the fuel cell.

Vorzugsweise wird das Odorierungsmedium dem Kraftstoffmedium in einer Konzentration zwischen 1 ppb und 200 ppm pro m3 Kraftstoffmedium beigemischt.Preferably, the odorization medium is added to the fuel medium in a concentration of between 1 ppb and 200 ppm per m 3 of fuel medium.

Die erfindungsgemäße Anordnung zur Odorierung eines Kraftstoffmediums sowie weitere Ausgestaltungen derselben seien nachfolgend anhand des in der Figur dargestellten Ausführungsbeispieles näher erläutert.The inventive arrangement for the odorization of a fuel medium and further embodiments the same will be described below with reference to FIG Embodiment explained in more detail.
