Definitions

  • This invention relates to a system for the displacement of fluids from within an enclosure and it relates more particularly to a means for the displacement of extremely cold liquids, and especially a liquefied gas such as liquefied natural gas.
  • Freezing of the shaft appears to result, in part, from foreign material in or about the shaft, which material becomes Stiffened at the low temperature to which the shaft and parts thereof are exposed when the tank is filled with the liquefied gas. Once the shaft becomes frozen, it is thereafter incapable of operation to effect liquid removal until the liquid is otherwise removed or hot gases are passed downwardly through the shaft to enable the shaft and parts associated therewith to become heated up to unfreezing temperature.
  • One of the means that has been devised to overcome the problem of freezing is continuously to rotate the shaft While the tank is being cooled down and loaded with the liquefied gas so that the shaft will remain free to rotate when reduced to the cold temperature of the liquid. Thereafter, the shaft can be occasionally rotated but it is preferred to continue rotation of the shaft to insure its freedom until placed into operation for removal of liquefied gas from the storage tank.
  • Another object is to provide a means for fluid displacement which does not make use of an elongate drive shaft extending through the liquid and which would thus be subject to distortion or binding due either to load or ternperature change or both.
  • a further object is to provide a means for the displacement of a cold liquid, such as liquefied natural gas, wherein use is made of relatively few simple parts which are readily available and easily installed into position of use; which are not subject to wide temperature changes between stages of operation or in operation and therefore free of becoming frozen or otherwise rendered inoperative due either to load or temperature change; which ernbodies an auxiliary means for effecting liquid removal in the event of failure of the pump; which is efficient and economical in operation; which generates sufficient vapor for displacement of the volume of liquid removed, otherwise it would be necessary to make use of a vapor return line from land storage to supply vapor for the liquid being displaced to avoid the development of subatmospheric conditions Within the container, and which can make use of the vapors of the liquids displaced as a driving force thereby to avoid the necessity for maintaining a sealing relationship between the elements and thereby also to make available an endless supply of the driving medium.
  • a cold liquid such as liquefied natural gas
  • FIG. l is a flow diagram schematically setting forth the arrangement of elements and flow of materials in accordance with the practice of this invention
  • FIG. 2 is a flow diagram similar to that of FIG. 1 showing a modification in the means and method for fluid displacement;
  • FIG. 3 is another flow diagram showing a still further modification
  • FIG. 4 is a flow diagram showing still another modification
  • FIG. 5 is a flow diagram showing still another modification.
  • FIG. 6 is a schematic illustration in section of a still further modification in the liquid flow diagram.
  • fluid displacement for the removal of the liquid from the container is effected by a submerged pump lll located adjacent the bottom side 12 of the container le and in which the means 16 for actuating the pump is similarly located so that all of the moving parts are maintained essentially at about the same temperature with very little distance separating the pump and its interconnected actuating means.
  • An imporant concept of this invention resides in the means for operation of said actuating means whereby moving parts subject to temperature differentials are substantially completely avoided and whereby the arrangement is substantially free of elements which might be subject to distortion or binding in a manner to cause failure of the displacement means.
  • Another important concept of this invention resides in the transmission of power for operation of the pump through liquids or vapors which can be selected to remain free of interferences from the cold liquid adapted to be displaced or else which can be intermixed with said liquid thereby not only to avoid the necessity for seals and problems of handling in use but also to make available new and novel concepts in liquid displacement and replacement of the volume of liquid displaced from the container as well as making available substantially limitless supplies of fluid for use in such power transmission.
  • the pump 10 which is adapted removably to be secured to the bottom side 12 of the tank 14 is of the conventional rotary type having an inlet in communication with the liquid 18 within the tank and an outlet 20 in communication with a delivery pipe 22 which extends upwardly to the top of the tank for connection to other facilities for storage or use of the liquid 18 displaced from the tank.
  • the turbine drive 16 is also removably secured to the bottom side 12 of the tank 14 with the drive shaft 24 of the turbine operatively connected to the rotor of the pump for actuation thereof.
  • it is provided with an inlet 26 at one end in cornmunication with a feed line 2S through which high pressured iiuid, liquid or gas can be introduced and an outlet 30 at the other end for exhaust of the spent gases, vapors, or liquid into the exhaust line 32.
  • novel combinations stem from the possibilities of operating the expansion turbine either by means of a vapor or gas or by means of a liquid or by means of a combination of liquid and gas.
  • novel ramifications also stern from the possibility of use of a liquid or a gas which is the same as the liquid or gas with which the container is lled or a liquid or gas other than that which is adapted to be displaced from the container.
  • FIG. l of the drawings illustrates a system which would be employed in the use of a driving liquid other than the liquid adapted to be displaced from the container, hereinafter referred to as liquefied natural gas, as representative.
  • Suitable driving liquids may be represented by liquid ethane, liquid propane, and liquefied triiiuorochloromethane and other liquids having a boiling point obove and a freezing point below the temperature of the liquefied natural gas.
  • the driving liquid 34 would be made available in a reservoir 36 located outside of the container. From the reservoir, the driving liquid would be fed to a pump 38 where it would be raised in pressure to the level desired for introduction into line 28 communieating the pump 3S with the expansion turbine 16. The spent driving liquid exhausted from the expansion turbine at lower pressure would be returned through line 32 to the accumulator or reservoir 36.
  • the driving liquid would rapidly approach the temperature of the liquefied natural gas since the driving liquid would be operating within a closed cycle during a large part of which it would be submerged below the liquid level.
  • the heat given up to the liquefied natural gas would stem primarily from ineiiiciencies of the turbine and pump units, including the heat of compression from the compression pump which in a way would be nullified by the cold of expansion during passage through the expansion turbine 16.
  • FiG. 2 of the drawings represents a system operating on the principles of a heat engine wherein the driving medium is a combination of liquid and gas.
  • the driving medium is a combination of liquid and gas.
  • Representative are such media as a higher boiling gas such as ethane, propane, butane, isobutane and the like, or other working medium which has a condensation point at a temperature above the temperature of the liquid in the tank but a freezing point at a temperature below the temperature of the liquid in the tank.
  • the medium in the form of a vapor is advanced through a condenser 40 in heat exchange relationship with the cold liquefied natural gas in the container to condense the driving medium to a liquid.
  • the body of cold liquid 18 will be able to condense the vapors exhausted from the expansion turbine l6 so that the exhaust line 42 may itself serve as the condenser.
  • the condenser 40 should operate to produce a sub-cooled liquid.
  • the absolute pressure in the condenser should be greater than Hd/ 1444-1 Where H is the height of the line 44, d is the density of the liquid in line 44 and P is the absolute pressure of the inlet side of the pump 46.
  • the condensed driving liquid is passed through line 44 to a pump 46 located outside of the container where the condensate is pressurized to a high level with very little expenditure of power.
  • the pressurized working liquid is passed through line 48 to a heat exchanger 50 for passage in heat exchange relationship with an elevated temperature medium such as air, water or steam tov heat the compressed working liquid to vaporize the compressed liquid to produce a large amount of gas at high pressure for passage through line 52 to the inlet of the expansion turbine 16.
  • the portionof the line 28 submerged in the iiquid is adapted to be insulated.
  • the principle of operation is to transfer heat from a high temperature driving medium to the always present low pressure liquid in storage whereby enough work can be made available to pump the liquefied gas for removal from the container.
  • the cycle described is one that embodies high eliiciency, especially from the standpoint of power requirements. Again the amount of heat transferred is suiiicient to boil off an amount of liquid in storage to replace the volume of liquid displaced by the pump.
  • the system shown in FIG. 3 is a modification of the system of FIG. l with the exception that the motive fluid is a gas preferably having a liquefaetion temperature and a freezing point temperature below the temperature of the liquid I8 within the container 14.
  • the driving gas can be selected of such media as nitrogen, helium or the like.
  • the driving gas is fed from a reservoir 5S through line 59 to a compressor pump 60 wherein the gas is raised t0 a high pressure for advancement through line 6l to a pressure regulator in the form of a surge pot 62. From the surge pot, the pressurized gas is fed through line 28 to the inlet of the expansion turbine 16. The expanded gas is exhausted from the turbine into line 32 for return to the accumulator 5S.
  • FIG. 4 there is illustrated a system operating on a gaseous phase similar to that of the flow diagram of FIG. 3 but in which the gaseous driving fluid is the same as the gas from the liquid being displaced from the container.
  • the gaseous driving fluid is the same as the gas from the liquid being displaced from the container.
  • the working medium would comprise natural gas.
  • natural gas as the driving fluid
  • the various novel ramilications are possible including utilization of the exhaust as a gas lift for discharge of the liquelied natural gas from the container either alone, in the event of failure of the pump, or in combination therewith.
  • the driving fluid can be exhausted into the container thereby to avoid the closed circuit necessary when strange materials are employed and thereby also to make driving lluid available from the vapor always present in the portion of the container above the liquid level.
  • vapor within the container above the liquid level can be withdrawn for use as a driving lluid through line dltiittted with a two-way check valve 65.
  • the vapor withdrawn is passed through line 66 to a compressor 63 wherein the vapor is raised to a high pressure for passage through line '70 to the inlet of the expansion turbine lo which operates to drive the centrifugal pump lll for the displacement of liquid 13 through the line 22.
  • the expanded vapors exhausted from the turbine lr6 are passed through line '72 into the line 22 whereby the exhausted gas rises through the line 22. to function as a gas litt which is eiective to raise the liquefied gas in line 22 to function as a removal means.
  • the material removed through the delivery line 22 will contain both the vapor and liquid, it communicates with a separator 74 wherein the vapor phase is separated from the liquid phase.
  • the liquid product drains from the separator into the line 76 for delivery while the vapor may be utilized to supply the working medium in line 66 or else returned to the vapor space within the tank in the event that an amount of vapor beyond that required for operation of the expansion turbine is available. It is for this reason that a two-way valve 65 is en ployed in line 6ft, in one position to admit vapor from the separator into the tank and in another position to permit withdrawal of vapor from the tank in the event that more is needed as a working medium.
  • line 76 has one end which communicates with line 7d between the compressor SS and a shut-oil valve 7S.
  • the other end ot line 7d communicates with the line 22 for the passage of compressed vapors from the compressor to the line 22 whereby the gas litt principle can be adapted for liquid removal.
  • Line 7e is provided with a shut-off valve titl for blocking the passage of compressed vapors therethrough until such time as the gas lift is desired to be placed into operation.
  • the driving iluid is again the vapor of the liquid that is being pumped.
  • the system in FIG. 5 is similar to that of FIG. 4 with the exception that means are embodied therein for the more efficient accumulation of vapors and liquids existing within the system.
  • the exhaust vapors from the expansion turbine are returned directly through line il@ to an accumulator 81 which also functions as a separator.
  • line '7h leading from the compressor 68 is provided with a by-pass 82 having a valve 84 for direct connection to the delivery line 22.
  • the delivery line 22 is further fitted with a branch line 86 having a valve 88 through which the delivery line 22 communicates with the accumulator 81.
  • valve 78 in the line 70 can be closed and valves 84 and 88 opened whereby vapor at high pressure is transmitted from the compressor pump 68 through lines 70 and 82 to the delivery line 22 for making use of the gas lift principle in removing the liquid from the tank.
  • the material from line 22 is introduced into the accumulator separator 81 wherein the liquid product is separated from the vapor.
  • the liquid is drained through line 90 into line 92 for delivery while the vapor is passed through line 94 either to the compressor or through line 96 back into the tank for filling the space previously occupied by the liquid.
  • the accumulator is provided with a relief valve 98 for release of pressure in the event that excess pressure should be developed in the vapor system during operation.
  • the material in line 22 is passed through line llltl to a separator 102 wherein the liquid is separated from the vapor.
  • the liquid product is drained through line 104 into line 106 for use while the vapor is removed through line 108 for return into line 94 which feeds either into the compressor or back into the tank or both, as previously described.
  • the expansion turbine is shown as being formed of turbine buckets dimensioned to operate within a truncated cone which, when fed by the vapor at high presssure, seeks its own true center and thus performs as a gas bearing.
  • booster pump in the delivery line 22 outside of the tank.
  • Such additional booster pump can be used to generate suflicient pressure for delivery 0f the liquid to storage and to divert part of the high pressure liquid back through line 2.2 and control valve 124 to the driving turbine on the submerged pump.
  • the submerged pump would only be called upon to develop enough pressure to raise the liquid to the top of the tank where the more eicient booster pump would take over for delivery to storage. This enables use of a submerged turbine and pump of considerably lesser power requirement.
  • the described arrangement also embodies flexibility for conversion into a gas lift for the removal of liquid from the container in the event of breakdown or failure of the turbine-pump unit.
  • the energy supplied to the driving fluid during compression provides heat suflicient to create vapors when transmitted to the liquid to make up the liquid withdrawn thereby to obviate the need to introduce other gases.
  • the pumping capacity can be balanced with the required amount of vapor for replacing the liquid removed.
  • the turbine-pump combination completely submerged in the liquid and adjacent the bottom side thereof for more complete delivery obviates the need for the use of long shafts in deep well pumps of the type heretofore subject to failure due to distortion or freezing. Further, the arrangement of the pump in the bottom of the container permits discharge of the liquid to levels as low as a few inches, the remainder of which can be stripped out from the tank with a gas lift pump.
