Definitions

  • This invention relates generally to a method of transferring liquefied gases and especially to a method of transferring such gases which are used for operating floating signal systems In such cases it is necessary to effect the transfer of the gas from the usual transportation drums with exclusion of air.
  • the present invention solves the problem in question by drawing the liquefied gas out of the transportation drum into the storage vessel whereby only that portion of the gas, which is converted into a gaseous state during the transfer, is forced by pressure and cooling into an empty transportation vessel and is again liquefied. According to this method, the greater portion of the liquefied gas is transferred without change of state which constitutes a much quicker and more economical operation.
  • the transferring method comprises the following steps:
  • the figure shows diagrammatically the transfer of the liquefied gas to a vessel having only one opening.
  • the figure shows how a storage vessel with one filling opening can be filled according to the invention.
  • a indicates the transportation drum to be transferred.
  • s is the vessel to be filled.
  • Vessel 10 e plays the role of an intermediate container. There is provided between a and s a pipe 0 having cocks b and r and also a branch pipe which latter leads through a valve (1 into the intermediate container e. In this branch pipe, the valve d is provided. That part of the intermediate container e, which is free from liquefied gas under all working conditions, communicates through the pipe g with valve. 1 and another adjoining pipe having the cocks h, i, l, m with the pump it and thence through pipe 12 with the cooling coil t and second transportation drum 0 through a valved pipe p.
  • the pipe with the cocks h, i, 1, m renders it possible to connect the intermediate container e selectively. to the suction or pressure side of the pump k. .
  • the second transportation drum 0 may be connected in a similar manner to opposite sides of the pump k.
  • the apparatus operates in the following manner:
  • the cocks 1', i and Z are closed, the cocks d, I, h, m and p are opened, the pump is and the cooling device t are set in operation and the apparatus evacuated.
  • the cock I) is then opened whereupon the liquefied gas is sucked in a liquid state into the intermediate container e.
  • the partially vaporized gas is drawn away in front of the pump it and forced through the cooling device it into the empty transportation drum 0 and the gas is again liquefied.
  • the cooks b, h' and m will be closed and r, l and iopened, the cooling'device t will be disconnected and then the pump will force the 5 to another liquefied gases with exclusion of atmospheric air, such gases being intended for burning or illuminating purposes and having a comparatively high boiling point or a slight over-pressure at room temperature, the gas being stored in a liquefied state;
  • said plant comprising, in combination with supply drum and storage vessel, a valved conduit between said supply drum and storage vessel, a second drum and a second valved conduit between said storage vessel and said second drum, a cooling device and a gas compressing pump in the second conduit, adapted to vaporize the gas and evacuate it from said storage vessel and conveying the vaporized gas to the second drum through said cooling device wherein the gas becomes reliquefied, an intermediary container inserted in the conduit between said storage vessel and the gas pump, and having connection with said first conduit.
