Application filed November 15, 1920. Serial No. 424,209.
T 0 all whom it may concern:
Be it known that I, PIERRE ANDRE PAUL VIoroR MAUCLERE, citizen of the Republic of France, residing in Paris, France, and whose post-office address is 14 Rue de Evurnon, have invented certain new and useful Improvements in Safety Apparatus for the Storage and Distribution of Inflammable and Other Liquids l/Vithin Tanks and Piping Out of Contact with the Air; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
This invention relates to apparatus for the safe storage and distribution of inflammable and other liquids within tanks and piping out of contact with the air, the liquid in the storage tanks is in all cases maintained exactly at atmospheric pressure under the protection of a suitable gas which is employed.
in a closed cycle. I
The invention according to this present application for improvements in the same is characterized by various modifications of the disposition of the apparatus and piping and by the use of a battery'of combined gaugingdevices disposed-at a lower level than the said storage tanks and employed to carry out the operations of withdrawal and distribution of the liquid, which operations may in factbe efl'fected at the same time that liquid at atmospheric pressure is admitted into said storage tanks, either by direct gravity feed or through the medium of a special battery of combined gauging devices.
This invention also relates to a simplified method of carrying out the installation wherein a special expansion receptacle for the gas constituting a barometricregulator is provided, thus obviating all direct action of the compressor upon said storage tanks, and in this case the movements of the inner volume of gas are effected directly by the displacements of the liquid, the compressor being solely employed to ensure the compensation between said expansion receptacle and a-pre'ssure receptacle used for feeding the gauging devices. This latter disposition also afl'ords the advantage of obviating all loss of vapors of the liquid in the atmos phere during the operations of storage, withdrawal and distribution of the liquid.
In the accompanying drawings,
Fig. 1 is a diagrammatic view showing the arrangement of an entire plant wherein two gas tanks are employed, one of said tanks being disposed on the intake side of the compressor and the second on the delivery side thereof, and the withdrawal and distribu tion of liquid are here effected by a battery of gauging devices. Fig. 2 is a similar view of a modified form of this disposition, wherein the separate sets of gauging devices are employed, one set for the storage and the second for the withdrawal and distribution.
In the construction shown in Fig. 1, the installation comprises one or more storage tanks 1 1*, two combined gauging devices 2 2 the piping 8 for the gravity filling of said gauging devices by the liquid from the storage tanks, a compressor 4, the piping 8 for emptying the portable supply casks 9, the connecting piping 13, and the oiftake piping 27 provided with the cook 87. The taps 7 30, 21 for the storage tanks and the taps 11, 15, 16, 17 for the gauging devices are used to effect the desired connections between the various parts of the plant.
On either side of the compressor 4 are disposed the expansion tank 46 and a pressure tank 5 which are connected to said compressor by the piping 18. The expansion tank 46 containing gas at atmospheric pressure is connected by the piping 47 with the taps-30 whereby it is connected through the piping 19 with either one of the storage tanks 1 1 The piping 47 is also provided with a valve 48 for making connection through piping 49 between thestorage tanks and the upper part of the supply casks 9. The valves 34 and 50 are disposed respectively upon the piping 8 and 49 at the connecting points of the flexible hose leading to the casks 9.v The expansion tank 46 is also connected by the piping 12 with the tap 15 and by means of this latter with either one of the gauging devices 2 2 The expansion tank 46 is provided wit-h an offtake piping 51 having disposed thereon an expansion device 32 and adapted for connection where required with a source of gas under pressure.
The pressure tank 5 is connected by the expansion device 35 to the tap 17 and'by this latter to the gauging devices.
The operation of the apparatus is as follows Stm'age.The cask 9 to be emptied is connected to the taps 3 1 and 50. These two taps are opened and the taps 7, 30 and 18 are disposed in the position shown. The liquid contained in the receptacle 9 flows freely by gravity into the tank 1" while the inert gas in said tank which is thereby displaced is caused to pass into the upper part of the cask 9. The connection afiorded through 18 with the tank 16 acts to maintain the upper portions of the receptacles at the atmospheric pressure.
The same conditions prevail for the operation of filling the storage tank i the taps 7 and 30 being in this case disposed in the opposite direction.
W z'thdrawctl 0f Z'i9'ui(Z.lVith the tap 21 in the position indicated, the liquid in the storagetank 1 flows freely by gravity into the gauging device 2 the tap 11 being turned in the position shown in Fig. 7.
Delivery and suppZy.-VVith the gauging device 2 in process of filling as above indicated and the taps 11, 16, 17, 15 in the posi tions represented, the pressure of the gas from the reservoir 5, which is expanded to the delivery pressure by the expansion de vice 35, is exerted through the piping 14.- upon the liquid in the gauging device 2 The said liquid is thus delivered through the piping 13 and 27 to the offtake cock 37.
At the same time, the gas which previously served to deliver the liquid from the gauging device 2 escapes through the piping 12 into the tank 46 in which it expands at the same time that th action of the compressor 4 brings it to atmospheric pressure.
IVhen the gauging device 2 is entirely emptied, the gauging device 2 being now filled, the operation commences in the contrary sense by the simple inversion of the taps 15,17, 16 and 11.
It should be observed that the storage tanks can be filled. and emptied in a simultaneous manner.
It will be understood that the present disposition provides tor the recovery of the vapors of the liquid which may be carried away by the gas, and especially as concerns the receptacles to be emptied. In "fact, inasmuch as the atmosphere of gas which is substituted for the liquid in. the receptacles to be emptied is previously saturated with vapors of the liquid at atmospheric pressure, there will occur no additional evaporation of the volume of liquid in the receptacle during the operation of emptying the latter. This arrangement therefore afi'ords the minimum loss of the vapors of the liquid as well as the maximum safety.
In the modified form of construction shown in Fig. 2, the general disposition of the apparatus is the same except that in this case the storage reservoirs are disposed at a higher level and are supplied by a series of additional gauging devices 2 and 2 These gauging devices are supplied by the piping 8 from the casks 9 and serve to dellver the liquid into the storage tanks 1, 1 through the valve 16 and the piping 8. In all other respects the operation of the gauging devices and the general installation is similar to what has been described with reference to the precedingembodiment of the invention.
