Definitions

  • the invention relates to a method and a device for reducing the pressure of gas from pressure vessels with a filling pressure of over 200 bar using a conventional pressure reducer for pressures up to 200 bar.
  • the gas withdrawal from pressure tanks with a filling pressure of up to 200 bar is made possible by means of pressure reducers, which reduce the tank pressure to a working pressure of usually less than 10 bar.
  • Filling pressure is understood to mean the pressure when the pressure container is filled to the maximum, while the container pressure means the current pressure of the pressure container during gas extraction.
  • the pressure reducers work in one or more stages. For example, you lower the pre-pressure on the tank side from 200 bar to a controllable back pressure of 2 to 20 bar on the side of the consumer or in two stages a pre-pressure of 200 bar first to 20 bar and then from 20 bar to 0.5 bar back pressure.
  • Such pressure reducers are used, for example, for gas extraction from bottles, cylinder battery or bundle battery systems which contain compressed gases, such as oxygen, nitrogen, argon etc., with a filling pressure of usually 200 bar.
  • a first pressure reducer for generating dry gas is used for gas sampling during gas analysis, with which the second pressure reducer and the rest of the system are dried. This first pressure reducer is then bypassed and the gas is passed through the second pressure reducer to the analysis unit.
  • liquid ammonia is brought from 250 bar to 9 to 12 bar and then to 1 to 2 bar by means of two pressure reducing valves before it is passed liquid and cryogenic into a container.
  • the consumer must equip himself with a system for pressure vessels with over 200 bar (e.g. 300 bar) and a second system for pressure vessels up to 200 bar (e.g. 200 or 150 bar) if they remain flexible and are not completely wants to commit to a certain filling pressure.
  • a system for pressure vessels with over 200 bar (e.g. 300 bar) and a second system for pressure vessels up to 200 bar (e.g. 200 or 150 bar) if they remain flexible and are not completely wants to commit to a certain filling pressure.
  • the consumer essentially only needs a pressure reducer which is connected upstream of his previous gas supply system.
  • This first pressure reducer reduces the pressure to or below 200 bar when using pressure vessels with a filling pressure above 200 bar during gas extraction, so that after this first reduction the pressure can be reduced to working pressure by means of a second pressure reducer.
  • the first pressure reducer is fully open and the second pressure reducer alone reduces the pressure to working pressure.
  • This second pressure reducer is usually already available in all gas supply systems. The method according to the invention therefore allows the use of gas containers with filling pressures above and below 200 bar by a single retrofitting.
  • the first pressure reducer has no effect since it is fully open and the system operates as usual.
  • the method according to the invention ensures compatibility of the system for, for example, 300 bar and 200 bar gas bottles, this compatibility being achieved with little technical and financial outlay. This also increases consumer acceptance for pressure vessels with filling pressures above 200 bar.
  • An advantageous variant of the method according to the invention consists in opening a bypass line which bypasses the first pressure reducer at a container pressure of equal to or less than 200 bar.
  • a bypass line which bypasses the first pressure reducer at a container pressure of equal to or less than 200 bar.
  • pressure vessels with a vessel pressure equal to or less than 200 bar can be emptied by bypassing the first pressure reducer.
  • the bypass line can be opened manually or automatically at tank pressures of 200 bar or below.
  • an oxygen gas bottle 1 with a filling pressure of 300 bar and a system for extracting gas from this pressure vessel according to the invention are schematically shown as pressure vessels.
  • the line leading from the gas bottle 1 to the consumer contains several pressure gauges 2, 3, 4 as well as a first pressure reducer 5, a bypass line 7, which can be opened and closed automatically with a control valve 6, and finally a second pressure reducer 8.
  • the second pressure reducer 8 corresponds to the previous system for gas extraction from pressure vessels with filling pressures up to a maximum of 200 bar.
  • this system is suitable for adding gas from an oxygen gas bottle 1 with a filling pressure of 300 bar by adding the first pressure reducer 5 with pressure gauge 2 and the bypass line 7 together with valve 6.
  • the first pressure reducer 5 lowers the pressure of the oxygen gas bottle to 200 bar when gas is withdrawn, as long as the pressure gauge 2 indicates container pressures of over 200 bar.
  • the gas then flows into the second pressure reducer, which lowers the gas pressure in two stages from 200 bar to 2 bar working pressure.
  • the oxygen can now be used, for example in laser cutting.
  • the valve 6 is automatically opened so that the gas flow can bypass the first pressure reducer 5 through the bypass line 7 and the gas pressure is reduced to working pressure only by means of the second pressure reducer 8.
  • the system according to the invention is of course also suitable for taking gas from oxygen gas bottles with a filling pressure equal to or below 200 bar.
  • the exemplary embodiment clearly shows the technical and financial advantages of the method according to the invention, by means of which the gas removal from pressure containers with filling pressures above and below 200 bar is possible with one system.
