Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Gewährleistung einer konstanten Gemischzusammensetzung bei der Lagerung von Flüssigkeiten und von verflüssigten Gasen.The invention relates to a method and a device to ensure a constant mixture composition when storing liquids and liquefied ones Gases.

Flüssigkeiten bzw. verflüssigte Gase werden in geschlossenen Behältern gelagert, aus denen sie in andere Behälter umgefüllt werden, die wiederum als Vorratsbehälter zur Umfüllung in noch kleinere Behälter dienen können.Liquids or liquefied gases are closed Containers stored from which they can be moved to other containers be transferred, which in turn are used as storage containers for transferring can serve in even smaller containers.

Bei unter Druck verflüssigten Gasen erfolgt die Entnahme mittels Eigendruck. Bei druckverflüssigten Gasen, die aus mehr als einer Komponenten bestehen, besteht die Gefahr, daß in Abhängigkeit vom Füllstand und Temperatur im jeweiligen Behälter eine mehr oder weniger große Gasphase entsteht, die sich in ihrer anteiligen Zusammensetzung von der Flüssigphase unterscheidet.The extraction takes place with gases liquefied under pressure by means of self-printing. In the case of pressure-liquefied gases that come from more than one component, there is a risk that depending on the level and temperature in each Container creates a more or less large gas phase that in their proportionate composition from the liquid phase different.

Bei verflüssigten Gasgemischen kann somit die Zusammensetzung der gasförmigen bzw. flüssigen Phase in Abhängigkeit von der Temperatur des Gemisches und dem Verhältnis zwischen Gas- und Flüssigkeitsvolumen variieren. Bei fallendem Behälterstand verändert sich somit die Zusammensetzung des Gemisches in der Gasphase und auch in der Flüssigphase. Diese Veränderung in der Zusammensetzung kann dazu führen, daß die Gemischzusammensetzung nicht mehr der eingefüllten Zusammensetzung des Gemisches entspricht. In the case of liquefied gas mixtures, the composition can therefore the gaseous or liquid phase depending on the temperature of the mixture and the ratio between Gas and liquid volumes vary. When the container level falls the composition of the mixture thus changes in the gas phase and also in the liquid phase. This Changes in the composition can lead to the Mixture composition no longer the filled composition of the mixture.

Diese Problematik tritt beispielsweise bei der Lagerung von verflüssigten Gasen für die Kältetechnik auf. In der Kältetechnik werden sowohl azeotrope Gemische als auch zeotrope Gemische verwendet. In zeotropen Gemischen sind die Zusammensetzungen der Gasphase und der damit im Gleichgewicht stehenden Flüssigphase nicht gleich.This problem occurs, for example, during storage of liquefied gases for refrigeration. In the Refrigeration technology is becoming both azeotropic and zeotropic Mixtures used. In zeotropic mixtures they are Compositions of the gas phase and the equilibrium with it standing liquid phase is not the same.

Das Kältemittel R407C enthält HFC32, HFC125 und HFC134a im Gewichtsverhältnis von 23:25:52 mit einer Toleranz von ± 2 Gew.-% je Komponente nach ARI 700/ASHRAE 34/DIN 8960. Wird dieses zeotrope Gemisch in einem üblichen Behälter gelagert und diesem Behälter die Flüssigphase entnommen, stellt man fest, daß es in der Flüssigphase zu einer Anreicherung von HFC134a und einer Abreicherung der beiden anderen Komponenten kommt. Entsprechend kommt es in der Gasphase zu einer Abreicherung von HFC134a und einer Anreicherung der beiden anderen Komponenten. Diese Verschiebung in der Zusammensetzung ist unerwünscht, da es zu damit verbundenen Störungen in der Kälteanlage kommen kann, die auf eine bestimmte Gemischzusammensetzung eingestellt ist. Die geplante Kälteleistung kann beispielsweise nicht erreicht werden.The refrigerant R407C contains HFC32, HFC125 and HFC134a in a weight ratio of 23:25:52 with a tolerance of ± 2% by weight per component according to ARI 700 / ASHRAE 34 / DIN 8960. This zeotropic mixture is stored in a conventional container and removed the liquid phase from this container it is found that there is an enrichment in the liquid phase of HFC134a and a depletion of the other two components comes. Accordingly, there is a gas phase Depletion of HFC134a and enrichment of the two other components. This shift in composition is undesirable because it causes interference in it the refrigeration system can come down to a certain mixture composition is set. The planned cooling capacity cannot be reached, for example.

JP 8-4997 beschreibt ein Verfahren mit dem die Konzentrationsveränderungen bei der Lagerung von verflüssigten Gasen und deren Entnahme aus den Lagerbehältern vermieden werden können. Gemäß diesem Verfahren wird gleichzeitig mit der Gasentnahme entweder ein Inertgas oder die Gaskomponente des verflüssigten Gasgemisches, welche den niedrigeren Siedepunkt besitzt und deshalb in der Gasphase angereichert wird, in den Lagerbehälter gedrückt.JP 8-4997 describes a method with which the concentration changes in the storage of liquefied Avoid gases and their removal from the storage containers can be. According to this procedure, the the gas extraction either an inert gas or the gas component of the liquefied gas mixture, which has the lower boiling point owns and is therefore enriched in the gas phase, pressed into the storage container.

EP 100 87 99 beschreibt ein Verfahren zur Bestimmung und Regulierung der Gemisch zusammensetzung gemäß des Oberbegriffs des Anspruchs 1.EP 100 87 99 describes a method for determining and Regulation of the mixture composition according to the Preamble of claim 1.

Die Aufgabe der Erfindung ist es, ein Verfahren und eine Vorrichtung anzugeben, bei denen die genannten Probleme nicht mehr auftreten. Die Aufgabe wird durch das erfindungsgemäße Verfahren sowie der dazugehörigen Vorrichtung gelöst. The object of the invention is a method and Specify device in which the problems mentioned are not occur more. The object is achieved by the invention Method and the associated device solved.

Das erfindungsgemäße Verfahren ist geeignet zur Bestimmung und Regulierung der Zusammensetzung von Flüssigkeiten und von verflüssigten Gasen, z. B. von druckverflüssigten zeotropen Gasgemischen, insbesondere zeotropen Kältemitteln.The method according to the invention is suitable for determining and regulating the composition of liquids and liquefied gases, z. B. from pressure-liquefied zeotropic gas mixtures, in particular zeotropic refrigerants.

Das erfindungsgemäße Verfahren ist dadurch gekennzeichnet, daß die Veränderung der Gasphasenzusammensetzung mittels eines Differenzdruckaufnehmers, der mit einem Behälter, in dem sich ein Eichgemisch befindet, und dem Lagerbehälter verbunden ist, ermittelt wird.The method according to the invention is characterized in that that the change in gas phase composition by means of a differential pressure sensor with a container in which is a calibration mixture, and connected to the storage container is determined.

Wenn die angezeigte Druckdifferenz einen bestimmten Wertkorridor verläßt, wird durch Nachdosierung der Gaskomponenten, die den höheren Partialdruck haben, die ursprüngliche Gemischzusammensetzung, insbesondere der Flüssigphase, wieder hergestellt.If the displayed pressure difference is a certain one Value corridor leaves, is by metering the gas components, that have the higher partial pressure, the original one Mixture composition, especially the liquid phase, again manufactured.

Das Nachdosieren geschieht so lange, bis der Druckdifferenzwert den vorher festgelegten Druckdifferenzbereich in die andere Richtung überschreitet.The dosing continues until the pressure difference value the previously defined pressure difference range in the other direction.

Mittels des verwendeten Differenzdruckaufnehmers wird die Druckdifferenz zwischen dem Eichgemisch und der Gasphase im Lagerbehälter ermittelt.By means of the differential pressure transducer used the pressure difference between the calibration mixture and the gas phase determined in the storage container.

Als Differenzdruckaufnehmer kann z. B. ein mechanisches Anzeigegerät, ein elektronischer Sensor oder auch ein U-Rohr verwendet werden.As a differential pressure transducer, for. B. a mechanical Display device, an electronic sensor or a U-tube be used.

Als Eichgemisch werden die Komponenten des zu lagernden Gemisches verwendet. Die Zusammensetzung des Eichgemisches richtet sich nach der tolerierbaren Zusammensetzung der Flüssigphase des Gemisches im Lagertank.The components of the to be stored are used as calibration mixture Mixture used. The composition of the calibration mixture depends on the tolerable composition of the liquid phase of the mixture in the storage tank.

In einer Ausführungsform wird HFC407c in einem geschlossenen Großbehälter gelagert. Dem Behälter wird die Flüssigphase entnommen. Zur Sicherstellung der Fluidzusammensetzung wird ein Gemisch aus HFC32 und HFC125 in den Lagertank nachdosiert. Dies geschieht solange, bis der Druck in dem Lagertank einen oberen Grenzwert erreicht hat, der über den Differenzdruckaufnehmer ablesbar ist.In one embodiment, HFC407c is closed Large containers stored. The container becomes the liquid phase taken. To ensure the fluid composition a mixture of HFC32 and HFC125 is replenished in the storage tank. This continues until the pressure in the storage tank has reached an upper limit that is above the differential pressure sensor is readable.

Da der Differenzdruckaufnehmer sehr genau arbeitet und als elektronisches Bauteil verfügbar ist, ist eine Verknüpfung der Meßstellen mit einer online Prozeßsteuerung möglich.Because the differential pressure transducer works very precisely and is available as an electronic component is a link of the measuring points possible with an online process control.

Der Differenzdruckaufnehmer und der Behälter für das Eichgemisch können neben, an oder in dem Lagerbehälter angebracht werden.The differential pressure sensor and the container for that Calibration mixtures can be attached next to, on or in the storage container become.

Es wurde gefunden, daß mit relativ einfachem Aufwand ein Nachdosieren der Gaskomponenten überwacht und das verflüssigte Gas in seiner Zusammensetzung sowohl in der Gasals auch in der Flüssigphase in einer bestimmten Zusammensetzung mit einer äußerst geringen Schwankungstoleranz gehalten werden kann. Die bisher übliche aufwendige Überprüfung der Zusammensetzung mittels GC-Analyse kann somit entfallen.It has been found that with relatively simple effort replenishment of the gas components is monitored and the liquefied Gas in its composition in both the gas and also in the liquid phase in a certain composition kept with an extremely low fluctuation tolerance can be. The usual time-consuming review of the Composition by means of GC analysis can thus be omitted.
