Definitions

  • the invention relates to a process for the regasification of cryogenic liquefied.
  • Gas in which a part of the located in an isolated tank cryogenic liquefied gas is spent by the tank in an insulated Dosier Boulevard, the Dosier1:00 is separated from the tank and a metered amount of cryogenic liquefied gas is then fed by activation of an evaporator circuit an evaporator, whereupon at the same time or subsequently the vaporized gas is filled into a high-pressure gas storage or fed into a mains network, whereupon the evaporator is separated from the metering, the pressure degraded in Dosier Boulevard and the dispenser is filled again with liquefied gas from the tank.
  • the invention further relates to a device for regasification of cryogenic liquefied gas comprising an insulated tank, an insulated dosing tank connected to the tank via at least one connecting line, an evaporator connected to the dosing tank via at least one connecting line and a return line and one connected to the evaporator High-pressure accumulator or connected to the evaporator line of a pipeline network, wherein the at least one connecting line between the tank and the Dosier immediately having at least one connecting line and the return line between the Dosier acids and the evaporator each have a shut-off valve.
  • WO 2011/009149 AI A method and a device of the type mentioned above, with which a piston-free compression of gases is possible, are known from WO 2011/009149 AI.
  • WO 2011/009149 AI are two or more Strands connected in parallel, being pressed with the pressure of one strand of the dosing memory for the filling of the other strand, especially the evaporator, empty.
  • the liquid enters the dosing tank downstream air evaporator, ie the liquid must be pressed against the pressure located in the evaporator in this.
  • the pressure in the dosing tank must be reduced before refilling the dosing tank with liquefied gas by releasing it through a throttle into the gas space of the tank.
  • the present invention aims to avoid the disadvantages of the prior art.
