18 Claims.
This invention relates to the storage of liquified gases and particularly to methods and apparatus adapted to minimize or prevent excessive evaporation due to heat leak from the environment.
The practice of storing liquefied gases of low boiling point, such as oxygen and nitrogen among others, involves the use of thermally insulated containers which substantially, but not completely, prevent the flow of heat from the surroundings to the liquefied gas. The small. but unavoidable, heat flow into the liquefied gas causes vaporization of the liquid. One way to avoid building up high gas pressures in the containers is to vent the vapor to the atmosphere. This practice results in a continuous loss of the valuable stored substance and consequently increases the final cost of that portion of the liquefied gas which is available for useful purposes.
It might seem, perhaps, that the losses by evaporation from storage containers are relatively inconsequential. However, the containers must be large compared to the daily consumption of the stored gas if the transportation of liquefied gases and the refilling of the containers are to be conducted in the most economical and reliable manner. If we assume a storage capacity of ten times the normal daily consumption, a daily loss by evaporation of 1% of the capacity of the container becomes of the daily consumption. This, of course, adds materially to the cost of the liquefied gas which is actually put to use.
It is the object of the present invention to provide an economical means for preventing excessive vaporization of liquefied gases while in storage and particularly to employ for that end the refrigerating capacity which is available when liquefied gas is withdrawn from a storage container for use or storage in the gaseous state. For most uses liquefied gases must be re-gasified. The latter operation involves a heat exchange process in which the available refrigeration generally has not been usefully employed.
The scope and advantages of the invention will become apparent by reference to the following illustrative descriptions of several of the particular methods by which the invention may be put into practice.
Figure 1 is a diagrammatic representation of apparatus adapted to accomplish the purposes of the invention;
Fig. 2 is a similar representation of a'modi fied form of the invention; and
container.
Fig. 3 represents another modification.
In carrying out the invention according to Fig. 1, liquid desired for utilization in the gasified state is withdrawn from the bottom of the container and pumped through a vaporizer and one or more heaters. The warmed, gaseous product is piped to the point of use. The vapor produced within the liquid storage container by the volatilizing effect of that heat which leaks from the atmosphere through the insulation of the container is withdrawn from the top part of the container, compressed to a suitable pressure and re-liquefied by heat exchange with the liquid withdrawn from the bottom of the The liquid produced by condensation of the vapor is returned to the storage container. This system eliminates the need for discharging vapor from the top of the storage container to the atmosphere with its irretrievable loss thereby.
Referring to Figure 1, l indicates a container for liquefied gas consisting of a metal tank of any suitable form and construction surrounded by media, 2, and supported by devices, which afford a high degree of thermal insulation of the liquefied gas from the atmosphere and adjacent bodies. For withdrawal of liquid from the container for useful employment, there is a pipe, 3, leading to pump l. The latter compresses the fluid to such pressures as may be desired for use or storage of the ultimate gaseous product. The efiiuent of the pump passes through pipe 5 to a vaporizer t where it is wholly or partly vaporized in compartment The vaporizer is supplied with heat by a stream of gas which is pumped through compartment [6 as hereinafter described. The effluent from compartment 1 is delivered through pipe 3 to a second vaporizer or heater 5, which raises the temperature of the fluid to the desired level.
In order to accomplish the particular purpose of the present invention, the vapor generated within the storage container I, as a consequence of heat leak through the insulation 2, and such. supporting devices as may be provided, is withdrawn through pipe 10 and conveyed to cornpressor II where the vapor is compressed to a pressure suitable for a re-condensation process. The compressed vapor leaves the compressor through pipe l2 and may be passed through an after-cooler [3 for removal of the heat of compression. The cooling medium in l3 may be either water or product gas which has passed through heater 9. Pipe 14 conveys the compressed gas to compartment It of vaporizer 5.
A surge tank i5 is connected to pipe M, or alternately it may be inserted in pipe I4. In compartment iii of vaporizer 6, the compressed vapor is cooled and liquefied by heat exchange with the cold fluid passing in counter current iiow through compartment i. The liquid condensed in compartment I6 is delivered through pipe 5'! and pressure regulating valve 18 to the liquefied gas container l.
Thus the invention effectuates a recovery, recondensation and return to storage of the valuable liquid which is vaporized by heat leaking through the insulation and supports of the container. The refrigeration required for the recondensation is obtained from the liquid which is withdrawn for use and which for most applications must be g-asified by absorption of heat whether the invention here described is practiced or not.
Actual operation of the system described requires various accessory and regulating devices of an obvious sort which, in order to simplify the description, have not been mentioned.
Figure 2 represents schematically a modification of the invention herein disclosed. apparatus provision is made for a situation in which liquefied gas may be withdrawn for use from the container only intermittently with relatively long periods between withdrawals.
For purposes of illustrative description, the liquified gas in storage is assumed to be liquid oxygen. Liquid oxygen vaporized within the storage container as a result of heat leakage is recondensed by allowing the vapor to enter a reflux condenser which is refrigerated by liquid air. The pressure in the container is maintained at a level which insures effective condensation of oxygen vapor by thermal contact with liquid air. The liquid oxygen condensed in the condenser drains back into the storage container. The liquid air supplied as refrigerant to the reflux condenser is produced from atmospheric air by heat exchange with liquid oxygen at those times when liquid is withdrawn from the storage container and gasified for useful employment. Compressed air is pumped through a Vaporizer counter current to the oxygen being withdrawn from the storage container. Since the rate at which liquid oxygen is vaporized in the vaporizer during a normal withdrawal is many times greater than the rate of vaporization within the container due to heat leak, a reserve supply of liquid air can be built up which is stored in an auxiliary, insulated container.
Referring to Figure 2, 2| is a container for liquid oxygen surrounded by suitable heat insulating media 22. Liquid oxygen which is to be gasified for use is withdrawn from the bottom of the container through pipe 23, compressed to a suitable pressure by pump 24 and delivered through pipe 25 to compartment 21 of a vaporizer 25. In compartment 2'! the liquid is vaporized by thermal exchange with a stream of compressed air flowing through compartment 28 In this 21. The liquid air produced in compartment 28 flows through pipe to expansion valves 36 and 31. Part of the liquid air is expanded through valve 36 into compartment 38 of a reflux condenser 38. The balance of the liquid air is expanded through valve 3'! and delivered into an insulated liquid air storage vessel 40.
Oxygen vaporized in container 2| by heat leakage through the insulation and supporting devices passes into coil M of the reflux condenser 39 where it is recondensed and drains back into the container. The liquid air boiled off in compartment 38 by the condensation of oxygen in coil 4| passes off through pipe 42. The cold evaporated air may be conducted through a coil 43 which is embedded in the insulatin material 22 surrounding container 2|. Heat flowing from the atmosphere through the insulating material may thus partially be absorbed by the coil air passing through the coil and prevented to some extent from reaching the liquid oxygen. When liquid oxygen is being withdrawn through vaporizer 25, compressor 30 is in operation and cold air reaching the point 44 from condenser 39 is drawn into the compressor through pipe 3|, together with additional air drawn from the atmosphere through pipe 45.
When vaporizer 25 and compressor 38 are not in operation, liquid air is Withdrawn from container 42'] through pipe 46 and forced by pump 41 through pipe 48 into compartment 38 oi condenser 39. Cold evaporated air reaching the point 4 from condenser 39 is discharged to the atmosphere through pipe 45.
Figure 3 represents an alternate arrangement for a part of the apparatus depicted by Figure 2.
This apparatus is adaptable to a liquid oxygen storage system from which liquid oxygen withdrawals are made at irregular intervals and at variable rates. Pum 51 is run continuously at a uniform speed and supplies liquid air to condenser coil 60 in an amount somewhat in excess of that required to condense the oxygen evaporated by the normal heat leakage into container 49. Liquid air is produced by compressor 52 and vaporizer 5| at the maximum rate possible whenever liquid oxygen is withdrawn from container 49-. The speed or compressor 52 may be coordinated with the speed of pump 50.
Various changes may be made in the details of construction as described and in the arrangement of the parts without departing from the invention or sacrificin the advantages thereof.
