Definitions

  • the "most expedient means for the relief of built-up pressure isto employ a pressure relief valve for each tank which will operate to vent off the vapors into the atmosphere when a predetermined pressure level is reached within the tank. If, on the other hand, the vapors are of economical importance, or have a commercial value which exceeds their cost of recovery or otherwise cannot safely be released to the atmosphere, it is desirable to recover the vapor as a liquefied material for return to the storage tank. Hence it is desirable to have a relatively simple and inexpensive system for recovering and recondensing the vapor-so that it can be returned to the liquid storage tank.
  • a recovery system consisting of a bath of a liquid refrigerant in which is submerged a condensing coil for each tank bringing, in a closed system, vaporized gases from the storage tank and returning the condensed and liquefied gases to the same tank.
  • a system as disclosed by this'invention permits one recovery system to serve on or more tanks using a relatively simple thermo-dynamic cycle.
  • the operation of the process of this invention may be more fully explained with reference to Figure l in which i a cycle is shown wherein gas is recovered and reconwith a filling line 33 having a valve 32. for the introduc of liquefied gas from the tank. While line 351 ⁇ is shown tion of the liquefied gas and which is.
  • the tank is partially filled with a liquid 21 selected to be at a temperature sufficiently low enough to recondense the gases entering through line 14 into the condensing coils 17 which are immersed in the liquid 21.
  • the temperature of the liquid should not be so low as to cause solidification of the liquid condensed in the coils 17.
  • the liquid 21 should be characterized by a temperature below the condensation temperature for the gas but above its solidification temperature. 'The liquid 21 does not fill the tank 19 so as to' leave an area 22,.much like the area 13 in the storage tank, to contain vapor formed by the vaporization of the liquid 21 upon the absorption of heat from the condensing vapors in the condensing coils 17.
  • the liquefied gases 12 (in the storage tank) and 21 (in the condensing tank) may be the same.
  • sufiicient differential in temperatures to efiect condensation of the gas from the storage tank may be achieved by maintaining a predetermined pressure in area 13 of the storage tank and a somewhat lower pressure in the area 22 of the recondensing tank.
  • the pressure difference in these two areas can be so adjusted as to fix the boiling points of the liquefied gases and thereby control the temperatures within the relatively small limits required.
  • the area 13 could be maintained under a pressure of about 16 p.s.i.a. while the pressure in the tank 19 could be maintained at about p.s.i.a.
  • the liquid 21 in which the condensing coil 17 is immersed may be a liquid different from the liquid 12 which is stored or shipped.
  • cooling liquid 21 is conveniently a liquefied gas, such as liquid nitrog n, liquid air, liquid helium or the like.
  • the choice of the liquid to be used will of course depend upon the liquefied gas 12 which is being stored. Normally, if the liquid 21 is not thesame as liquid 12, then liquid 21 should have a boiling point a little below the boilingpoint of the liquid 12, unless, as in the case where the liquids are identical, a sufiicient temperature differential can be achieved by proper control of pressures in the areas 13 and 22.
  • Alternate methods for returning the liquefied gas from the recondensing system to the tanks 10 may be employed instead of the blower 16 used to force the gas through the coil 17 and into the return line 18.
  • a gravity feed system may be provided if the recondensing system is elevated safely above the tank 10 and. the coils 17 and so oriented as to permit the liquid to drain out as it is a formed. it is also possible to make use of a liquid pump in thereturn line 18 to direct the liquefied gas to the tank 19.
  • the recondensing system may serve to recondense the gases from a single storage tank or from a plurality of storage tanks.
  • the recondensing system of this invention will also serve a plurality of tanks containing dilferent liquefied gases; but if the gases to be stored or shipped are different, their boiling points at the pressures at which they aremaintained should not vary so widely that the liquid 21 in the tank 19 would solidify any one or fail to liquefy another.
  • the cooling ele ment 24 as a recondensing system for gases which have considerably higher boiling points than those stored in tank 10 and which are to be shipped or stored over a" period of time.
  • a system embodying condensing coils and valves similar to that shown leading from tank 10 may be used to circulate the gas though the cooling element 24.
  • the system of this inventiorn'a's illustrated in Figure 1, may be varied in many ways which will occur to those skilled in the art without departing from the scope of the invention.
  • the number of storage tanks served by one recondensing system may be any convenient number and the storage tanks may be arranged in various ways in relation to the recondensing system.
  • the storage and recondensing tanks along with their insulations may be-of any suitable metal, suchas stainless steel, aluminum, or of other material, for storing liquefied gas atlow temperatures, -white' such additional equipment as compressors, expansion valves,- auxiliary cooling systems, etc. will be chosen with regard tothe gases'to be handled and the temperatures involved.
  • the lines leading from the various parts of the system may desirably be insulated. in any proper manner to minimize thermallosses and heat leaks.
  • the systemembodying affords 'a' means for minimizing losses of liquefiedgases which are normally encountered in storage-or in the shipment of such liquefied gases over'an extended. period of time or under conditions where heat. leaks into the receptacles are relatively large. These losses are minimized by the used a fairly simple but. efiicient system for recondensingthe gases released by vaporization of the liquefiedigas during such shipment or'storage. system which can serve a numbcr of storage .or shipping receptacles and which, at the.
  • Method of recovering gas boiled ofi? from a plurality of tanks containing liquefied gas at about atmospheric pressure and for return of the liquid to each of said tanks in about the amount boiled off to maintain balance which comprises conducting said gas from each of said tanks through closed circuits passing through a liquid bath in a recondensing system at a temperature below the boiling point and above the solidifying point of said liquefied gas, thereby causing said gas to liquefy, returning the resulting liquefied gas to said tanks, compressign, cooling, and expanding the vapor boiled off from said liquid bath, and returning the resulting liquefied vapor to said liquid bath.
  • liquid bath consists of a quantity of said liquefied gas and said liquid bath is maintained at the required temperature by maintaining its pressure below the pressure of said liquefied gas.
  • Apparatus for recovering boil-01f gas comprising a plurality of tanks containing a liquefied gas which boils at a temperature far below ambient temperature, a heat exchanger separate and apart from the tanks, means for circulating a liquid refrigerant through said heat exchanger wherein the liquid refrigerant is maintained at a temperature below the boiling point temperature of the liquefied gas but above the solidification temperature of said gas, separate closed circuit means including means separate for each of the tanks for drawing off gas that has been vaporized, means for passing said draw-off gas through said common heat exchanger in heat exchange relationship with the refrigerant, and means for returning the condensed gas from the heat exchanger to the tank from which the gas was removed.
