Abstract:
A system and method enable intelligent refuelling of a pressurised vessel. The method includes receiving a gas at a refuelling port, wherein the refuelling port is coupled to the pressure vessel; determining a temperature 5 of the pressure vessel; determining a pressure of the pressure vessel; directing the gas through a nozzle, wherein the pressure vessel and nozzle are thermally coupled such that Joule-Thomson expansion of a gas flowing through the nozzle cools an interior cavity of the pressure vessel; and controlling a shut-off valve according to an amount of gas in the pressure 10 vessel determined according to the temperature and pressure, wherein the shut-off valve is located between the refuelling port and the pressure vessel, for controlling a flow of gas between the refuelling port and the pressure vessel.
Abstract:
Die Erfindung betrifft ein Verfahren zum Regeln des Drucks in einem ersten Behälter (1), aufweisend ein in flüssiger und gasförmiger Phase vorliegendes Stoffgemisch, aufweisend eine erste Komponente und eine zweite Komponente, wobei bei dem Verfahren die Temperatur des Stoffgemischs so eingestellt wird, dass der Druck im ersten Behälter (1) unterhalb eines vordefinierbaren Wertes liegt und das Stoffgemisch bei der eingestellten Temperatur und dem Druck im ersten Behälter (1) nur in der flüssigen und gasförmigen Phase (F, G) vorliegt.
Abstract:
measurement device for monitoring the level of liquefied gas in a canister is described. The device comprises an array of at least three temperature sensors, configured to be mounted externally of the canister to extend from a first position on the canister to a second position on the canister. The device also comprises detection circuitry for detecting, when gas is released from the canister causing a temperature drop at the liquid-gas interface within the canister, a subset of the temperature sensors measuring a lower temperature than the remainder of the temperature sensors, and for identifying a current level of the liquefied gas in the canister based on the position within the array of the subset of the temperature sensors detected as measuring a lower temperature. This arrangement can be retrofitted to any canister, without the need to modify the canister or change the valve arrangement.

Die Erfindung sieht ein Verfahren zur Ermittlung einer Füllmasse in einem wärmeisolierten Behälter für ein kryogen gespeichertes Gas vor, wobei die Füllmasse über ein bekanntes Behältervolumen und eine errechnete Dichte des Gasinhalts des Behälters bestimmt wird, deren Wert aus einer Behälterdruckrmessung und einer Temperaturmessung errechnet wird. Das Verfahren ist dadurch gekennzeichnet, dass ein Temperatursensor eingesetzt wird zur Messung einer Mischtemperatur einer flüssigen und einer gasförmigen Phase des Gases, die flüssige Phase entnommen über eine erste Entnahmezuleitung an der geodätisch niedrigsten und die gasförmige Phase entnommen über eine zweite Entnahmezuleitung an der geodätisch höchsten Steile des Behälterhohlraums, wobei der Temperatursensor stromabwärts der Entnahmesteilen, nach einer Zusammenführung der ersten und der zweiten Entnahmezuleitung, zu einer einzigen, aus dem Behälter herausführenden Entnahmeleitung, in oder außen an dieser, dort platziert ist, wo eine vollständige Durchmischung der flüssigen und der gasförmigen Phase des Gases aus der ersten und zweiten Entnahmezuleitung bereits erfolgt ist.
