Definitions
- the invention relates to a method for cyclic pistonless compression of the gas phase cryogenic liquefied gases.
- 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 are to be filled with such a system with a pressure of, for example, 200 bar or 300 bar, it is usually necessary to use approximately 40 KWh of power for the compression for 1000 NmVh. 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 substantially reduce the power to be used in such known methods for the evaporation and filling under pressure, and has the aim to dispense with the use of pumps and compressors, which in addition to an improvement in the current account also to a reduced maintenance costs leads.
- the inventive method of the type mentioned is essentially that deep-liquefied 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 Dosier disposer is again filled with liquid gas and the pressure in the last used evaporator used to squeeze the liquid gas from the dosing into another evaporator, each cyclically different from each other vaporizers are fed from the dosing and the pressure in the dosing and, if necessary, in each case filling evaporator is reduced 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 quantity and, if the volume is known, a definite nierter of the supplied heat associated pressure is built up.
- a pressure equalization to the evaporator occurs here and when the system is started up, after a further loading of the metering container, it is sufficient to transfer the remaining vapor pressure in the currently used evaporator for expressing the metered quantity of liquefied gas into another one allow atmospheric and lower pressure than the pressure in the evaporator currently in use evaporator. It is thus charged with the remaining pressure of the currently used evaporator another evaporator and in the evaporation carried out there again, the vapor pressure built up, which is provided in the sequence for filling the tank of the bottles or the feed into the pipeline network.
- the procedure is such that the pressure reduction from the metering vessel or the evaporator is reduced via a throttle into the gas space of the tank, a consumer or the atmosphere.
- throttle here refers to any device which • the pressure reduction is used.
- 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 Throttling is carried out by spraying liquefied gas and subsequent mixing condensation.
- the gas can be pressed from below through the liquid or condensed by blowing liquid into the gas.
- a suitably 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 filled before the start of the first mixing - Steaming cold.
- 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 there is a second evaporator E, wherein alternately from the respectively active evaporator a schematically with F recorded consumer device, such as a bottle is filled.
- G schematically indicates a balance for the quantity filled into the dosing container B. Likewise, there is a scale indicated by H for the measurement of the filled into the bottle F amount.
- 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 cryogenic tank A, the remaining equipment, and in particular the metering and the evaporators D and E in this initial phase are 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, taking into account the measured values of the balance G. ,
- 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.
