Description
Verfahren zum Aufbewahren und Versand von durch Abkühlung kondensierten, insbesondere von festen Brenngasen Die Aufbewahrung und der Versand von durch Abkühlung kondensierten Brenngasen bringen gegenüber der in ähnlicher Weise verwendeten festen Kohlensäure insofern Schwierigkeiten, als das Brenngas, welches aus dem festen Zustand in den gasförmigen übertritt, feuergefährlich ist. Insbesondere kann durch die allmähliche Verdampfung, beispielsweise von Acetylen, ein explosives Gasluftgemisch entstehen. Ein gasdichter Verschluß der Aufbewahrungsgefäße ist nicht möglich, weil durch die allmähliche Wärmezufuhr der Druck im Aufbewahrungsgefäß steigt und insbesondere Acetylen bei höheren Drucken zum Zerfall unter Explosionserscheinung neigt. Es ist bereits vorgeschlagen worden, kondensierte Gase durch Anwendung eines Gases von niedrigerer Siedetemperatur als das kalt zu haltende Gas aufbewahrungs-und transportfähig zu machen. Zu diesem Zwecke sollten die abziehenden Dämpfe des verflüssigten Kühlgases an dem das aufzubewahrende Gas enthaltenden Behälter vorbeistreichen und auf diese Weise die eindringende Wärme abhalten. Diesem Verfahren haftet jedoch der Mangel an, daß zum Zwecke der Kühlhaltung eine außerordentlich große Menge verdampfendes Gas erforderlich ist, weil nur die spezifische Wärme dieses Gases für die Wärineaufnahrile ausgerrutzt werden kann.Procedure for storing and shipping refrigerated condensed, especially of solid fuel gases The storage and shipping of by refrigeration condensed fuel gases bring about the solid ones used in a similar way Carbonic acid insofar as the fuel gas, which comes from the solid state, is difficult in the gaseous form is flammable. In particular, can through the gradual Evaporation, for example of acetylene, creates an explosive gas-air mixture. A gas-tight closure of the storage vessels is not possible because of the Gradual heat supply increases the pressure in the storage vessel and in particular At higher pressures, acetylene tends to decompose and explode. It is has already been proposed to use a gas of condensed gases lower boiling temperature than the gas to be kept cold can be stored and transported close. For this purpose, the evacuating vapors of the liquefied cooling gas should be used Swipe past the container containing the gas to be stored and onto it Way to keep out the penetrating heat. However, the defect is liable to this procedure indicates that an extraordinarily large amount of evaporating for the purpose of refrigeration Gas is required because only the specific heat of this gas for the Wärinaufnahrile can be exploited.
Die vorliegende Erfindung sieht als Kälteträger, welcher die eindringende Wärme aufzunehmen hat, nicht Gas, sondern Flüssigkeit vor und erreicht dadurch gegenüber dem bisherigen Stande der Technik einerseits eine bessere Wärmeleitung zwischen Kühlmittel und Kühlgut und andererseits die Möglichkeit der Ausnutzung der latenten Ver dampfungs- bzw. Schmelzwärme der Flüssigkeit, welche gegenüber der spezifischen Wärme des Gases erheblich größer ist. Es gibt die verschiedensten Ausführungsmöglichkeiten des @"erfahrens. Eine der wichtigsten ist die Anwendung flüssigen Stickstoffs als Kältebad. Es läßt sich aber auch das Verfahren so ausführen, daß man das Gefäß., welches das feste bzw. flüssige Gas enthält, in einem Kältebad von flüssiger Luft, fester Kohlensäure o. dgl. aufbewahrt, oder aber das Kältebad kann aus einem festen Körper, der im Gleichgewicht mit seiner Schmelze steht, bestehen, sofern der Schmelzpunkt genügend lief liegt, was z. B. bei kondensiertem Acetylen für Methylalkohol und Pentan zutrifft. Es sei ausdrücklich bemerkt, daß die Temperatur des Käitebades über dem Sublimationspunkt und sogar Tripelpunkt liegen kann, vorausgesetzt, daß nur im Aufbewahrungsgefäß eine Drucksteigerung bis zur Explosionsgrenze vermieden wird.The present invention sees as a refrigerant, which the penetrating Has to absorb heat, not gas, but liquid in front and thereby achieved opposite the prior art on the one hand better heat conduction between Coolant and goods to be cooled and, on the other hand, the possibility of exploiting the latent Ver evaporation or heat of fusion of the liquid, which compared to the specific Heat of the gas is considerably greater. There are many different design options des @ ". One of the most important is the use of liquid nitrogen as a Cold bath. However, the method can also be carried out in such a way that the vessel., which contains the solid or liquid gas, in a cold bath of liquid air, solid carbonic acid or the like. Or the cold bath can consist of a solid Body that is in equilibrium with its melt exist provided the melting point enough ran is what z. B. with condensed acetylene for methyl alcohol and Pentane applies. It should be expressly noted that the temperature of the cold bath can be above the sublimation point and even triple point, provided that an increase in pressure up to the explosion limit is only avoided in the storage vessel will.
