Definitions

  • the invention relates to a method for cyclic pistonless compression of the gas phase cryogenic liquefied gases.
  • a method for cyclic pistonless compression of the gas phase cryogenic liquefied gases is for example from the document US-17-2,035,396 known.
  • Substantial energy is used to liquefy gases, with the energy of overheating and evaporation removed from the product.
  • Refrigerated liquefied gases are stored in so-called cryo-tanks.
  • Cryo-tanks which may be stationary, are used as latches for the use of gases in the gaseous state.
  • the gases are removed from such a cryo-tank and converted into the gaseous state, with high-performance high-pressure pumps generally being used for this purpose.
  • the liquid is forced by means of such high pressure pumps in the evaporator, wherein the ambient heat or external energy is used for evaporation in the evaporator.
  • the liquid gases are immediately evaporated and subsequently compressed by gas compressors to the desired pressure. If gas cylinders with a pressure of, for example, 200 bar or 300 bar are to be filled with such systems, it is usually necessary to use about 40 KWh of power for 1000 Nm 3 / h for the compression. If not the liquid but that already vaporized gas is to be compressed in the sequence, the same amount requires a power of about 400 KWh.
  • the invention now aims to significantly reduce the costs incurred in such known methods for the evaporation and filling under pressure power, and has the aim to dispense with the use of pumps and compressors, which in addition to an improvement in the power balance and reduced maintenance leads.
  • the inventive method of the type mentioned is essentially that cryogenic liquefied gas is placed in a dosing and a metered amount is fed to an evaporator, whereupon the vaporized gas is filled or fed into a pipeline network, whereupon the dosing again is filled with liquid gas and the pressure in the last used evaporator is used to squeeze the liquid gas from the dosing into another evaporator, each cyclically different from each other evaporators are fed from the dosing and the pressure in the dosing and, if necessary, in each case to be filled evaporator is degraded before a renewed introduction of a metered amount of the liquefied gas.
  • cryogenic liquefied gases are spent in a dosing, can be used without the aid of the pump directly with the initially in a cryogenic tank usually initially existing vapor pressure of about 5 bar or the geodetic pressure to this transport of the cryogenic liquefied gas in the Dosing to accomplish.
  • the fact that the amount is metered in the sequence which, as it corresponds to a preferred development of the method according to the invention can be done in a simple manner, for example by weighing the metered dose spent in the dosing, it is ensured that in the episode during evaporation a whole certain amount and with known volume a defined the pressure applied to the heat supplied is built up.
  • the required pressure reduction can be made in principle in various ways. According to a preferred embodiment of the method according to the invention is in this case proceeded so that the pressure reduction from the metering vessel or the evaporator is reduced via a throttle in the gas space of the tank, a consumer or the atmosphere.
  • throttle means any device which serves to reduce the pressure.
  • Conventional pressure reducing valves are here due to the temperature conditions, as they occur when working with liquefied gases and the respective expansions, suitable only conditionally, the pressure reduction could of course also be done by forwarding in another consumer and / or against the atmosphere, if as in 2 In case of gas losses can be accepted.
  • the procedure is that the pressure reduction in a condenser is made as a throttle.
  • a condenser serves to substantially reduce the volume, since liquid gas is again eliminated from the gas phase and in this way the pressure is drastically reduced.
  • Such a condenser thus meets the criteria of the invention required throttle to return the gas and the liquid in the sequence in the cryo-tank, which indeed has a much lower vapor pressure.
  • this procedure can be such that the liquefaction and the pressure reduction in the Throttle by spraying liquefied gas and subsequent mixing condensation is made.
  • the gas can be pressed from below through the liquid or condensed by blowing liquid into the gas.
  • a correspondingly defined initial state must be set at the beginning, for which the procedure according to the invention is advantageously such that the containers, condenser and pipelines are cold-rolled before the start of the first evaporation ,
  • A designates a cryo-tank.
  • B denotes a metering container, wherein in the line leading to the cryo-tank, a condenser designated C is switched on as a throttle.
  • D denotes a first evaporator. Parallel to this first evaporator D exists a second evaporator E, wherein alternately from the respective active evaporator a schematically denoted by F.
  • Consumer device such as a bottle is filled.
  • valves connected in the respectively marked lines are designated consecutively with 1 to 19 and connected as follows in the individual process steps:
  • the product is liquid in the cryo-tank A, wherein the remaining facilities, and in particular the dosing B and the evaporators D and E are in this initial phase at atmospheric pressure.
  • Cryo-Tank A there is a slight overpressure of mostly about 5 bar.
  • liquid product flows under the pressure in the cryo-tank in the condenser C until the gas phase is in equilibrium with the liquid phase.
  • An opening of the valves 10 and 11 leads to the venting of gas initially located in the condenser in the atmosphere or in the gas space of the cryo-tank A.
  • valves 1, 3 and 8 are opened.
  • liquid product flows from the cryo-tank into the dosing tank, the valves being closed when the predetermined dosing weight determined by the balance G is reached.
  • Through the valve 8 is vented in the open position of the dosing against the cryo-tank A.
  • valves 1, 3 and 8 are again opened, whereupon cryogenic liquefied gas in turn flows from the cryo-tank A into the dosing tank B and, as described above, a dosage is carried out, the measured values of the balance G being taken into account.
  • the metered amount of cryogenic liquefied gas is pressed with the prevailing pressure in the evaporator D from the dosing into the further evaporator E, whereupon the valves are closed again , Subsequently, the cryogenic liquefied gas evaporates in the evaporator E, after which the valves 15 and 19 are opened after complete evaporation and again a container or the bottle F can be filled. After a check by means of the balance H, the valves are closed again so that now the evaporator and the dosing tank are under a correspondingly higher pressure than at the beginning of the process.
  • the pressure remaining in the evaporator E can again be used by opening the valves 4 and 6 and 16 to press the metered quantity of liquefied gas into the evaporator D, whereupon, as already described above, continues to proceed.
