Definitions
- the invention relates to a compressed gas container with one or more openings for connecting sensors.
- the manometric method is based on measuring the change in pressure after adding the individual gas components.
- the Gas components in succession up to a defined pressure in the Pressurized gas bottle filled the pressure increase during a filling step is at least several bars.
- Gas mixtures with one component in the Trace areas are produced using mother mixtures which are used in the Pressurized gas cylinder submitted in excess pressure and with the main component up be filled up for final pressure.
- the pressure measurement was previously carried out before Pressurized gas bottle in the gas pipeline. Due to pressure drops at Constrictions in the gas pipeline path, especially on the gas cylinder valve, can the measured pressure deviate significantly from the pressure in the gas bottle (when applying overpressure or underpressure). A precise one Pressure measurement during gas filling is therefore not with the desired reliability possible.
- the invention has for its object requirements for an accurate Pressure measurement when filling gases in compressed gas containers and at Creating gas mixtures in pressurized gas containers.
- the pressurized gas container is preferably a pressurized gas bottle, e.g. Legs Commercially available compressed gas bottle with 50, 40, 20, 10, 5, 2, 1 or 0.5 liters Bottle volume with one or more openings next to the opening for the cylinder valve is provided. The openings are used to hold z.
- Pressurized gas containers according to the invention in particular pressurized gas bottles and Pressure cans are referred to below as measuring containers.
- Pressurized gas cylinders are usually not added for safety reasons Provide openings (e.g. holes).
- the modification of pressurized gas containers according to the invention taking safety precautions or Safety requirements are justifiable for measurement purposes.
- High pressure area e.g. B. 10 to 350 bar, is the use of modified Compressed gas cylinders possible under appropriate safety precautions.
- the measuring container is advantageous in the application (e.g. for pressure measurement) connected in parallel to other compressed gas tanks. It is particularly advantageous if the measuring container is made from a pressurized gas container that parallel connected compressed gas tanks. If the containers are identical the same conditions then prevail in the measuring container as in the Pressurized gas containers for gas filling. The measuring container is easily in one Filling level can be integrated.
- the measuring container is suitable, for example, for measuring pressure and / or Temperature.
- Temperature sensors e.g. thermocouples
- the measuring container is suitable, for example, for measuring pressure and / or Temperature.
- Openings can also be used for guest removal for analysis purposes, e.g. B. in connection with high pressure metering valves or shut-off valves. Based several openings, e.g. B. along the longitudinal axis of the pressurized gas container, the local gas composition can be determined, especially for testing the Homogeneity of gas mixtures or to determine gas stratification in the Gas mixture production.
- the gas composition can be determined using gas samples taken or determined online. Analysis methods are e.g. B. Mass spectrometry or infrared spectroscopy, especially FT-IR spectroscopy.
- the openings can also be used to hold probes for examining the Serve the inner surface of pressurized gas containers (e.g. endoscope; spectroscopic Surface investigations; Gas analysis using mass spectrometry). For example, adsorption and desorption processes for quality control are recorded (e.g. change in gas composition using mass spectrometry).
- pressurized gas containers e.g. endoscope; spectroscopic Surface investigations; Gas analysis using mass spectrometry.
- adsorption and desorption processes for quality control are recorded (e.g. change in gas composition using mass spectrometry).
- the openings in the pressurized gas container wall are preferably threaded provided, e.g. B. Conical threads such as NPT 1/16 inch to NPT 1 ⁇ 4 inch. 1/16 and 1 ⁇ 4 Inch threads can e.g. B. at least 5 mm wall thickness. Threaded openings are particularly suitable for use in high pressure areas. Soldered or welded connections are generally used Low pressure range (e.g. for thin-walled containers such as pressure cells).
- the measuring container can be used particularly advantageously for precise pressure measurement in manometric processes for the production of gas mixtures.
- gas dosing with partial pressure measurement e.g. B. for pressures below 1000 mbar
- the measuring container with pressure measuring device ensures exact and transferable measured values for the compressed gas containers during gas filling.
- the partial pressure of the secondary component in the compressed gas containers can be precisely determined.
- the vacuum measuring tubes are usually located relatively close to the filling stations in the suction area of the vacuum pumps. (Pressure gauges are usually located in the filling pipe system). The pressure in the compressed gas bottle is not measured with sufficient accuracy. This problem is solved with the measuring container connected in parallel to the filling compressed gas cylinders ( Dummy bottle ”) solved, which is preferably equipped with one or more gas-independent absolute pressure measuring tubes and thus reflects the real pressure in each compressed gas bottle.
- the measuring container can either be shut off from the filling gas line or it can a shut-off valve between the measuring container and the measuring device which is closed as soon as the permissible measuring pressure range is exceeded It can be advantageous to use several measuring containers, eg a measuring container for measuring in the low pressure range and a measuring container in the medium and high pressure range.
- the commonly used vacuum measuring tubes e.g. B. Thermovac, Pirani or Due to the measuring principle, Penning measuring tubes are strongly dependent on the type of gas Pressure measurement.
- the pressure display in these measuring devices is not is linear.
- measuring systems are preferred which allow an absolute pressure measurement independent of the gas type.
- An absolute pressure measurement that is independent of the gas type can be used, for example Pressure measuring devices such as capacity gauges (e.g. device with the designation 600 Barocel® from Edwards, USA; Measuring ranges: 0-10, 0-100, 0-1000 mbar) respectively.
- capacity gauges e.g. device with the designation 600 Barocel® from Edwards, USA; Measuring ranges: 0-10, 0-100, 0-1000 mbar
- the inlet pressure directs a thin, membrane welded radially in the housing opposite a fixed electrode both electrodes form a capacitor. This leads to a Change in capacity after electronic signal processing via the control and Display electronics is directly proportional to the pressure.
- As an output signal a linear DC voltage is supplied.
- the reference electrode is in one Reference ultra-high vacuum space that is long-term stable thanks to chemical getters.
- Gas-independent measuring tubes for capacitive measurement are for pressures of for example 0.0001 mbar to 1000 mbar available.
- the measuring container advantageously contains an external connection Evacuation option for faster calibration of vacuum measuring tubes:
- the Connection is for example attached to the side of a compressed gas bottle.
- the use of the measuring container is advantageous for all manometric Process for the preparation of gas mixtures, in particular in the Pressure measurement in processes for the production of gas mixtures in Pressurized gas containers where, in at least one step, a pressure of a Gases is roughly specified (coarse pressure) and then a smaller more precise Pressure (fine pressure) in the compressed gas container with the help of a vacuum is set.
- the fine pressure is, for example, in the range from 0.0001 to 1000 mbar 15 ° C.
- the use of the measuring container is particularly advantageous during production a gas mixture with a main component and one Secondary component, which in a small concentration, for. B. in the trace area, is present.
- the filling and metering takes place advantageous first with the gas component to be produced in the
- the gas mixture is in the lowest concentration (secondary component) because the first dosing step in the process with the greatest accuracy can be executed.
- the flushed, conditioned and evacuated compressed gas container is with the filled the first gas component.
- the first gas component is filled initially up to a coarse print that is larger than the actual one Dosing pressure, through which the amount of the gas component is determined.
- Coarse pressure is generally in the range of 0.1 to 10 bar, preferably in the range from 0.1 to 5 bar and particularly preferably in Range from 0.8 to 1.5 bar, depending on the fine pressure to be set.
- Fine print and coarse print should be so far apart that one Dosing by means of vacuum can be carried out well. This is for example, if the fine pressure is about 10 percent below the Coarse pressure value. Especially if the fine impression is below 100 millibars, especially less than 10 millibars, the change is made Pressure when applying the vacuum slowly, so that the desired value of the fine impression can be set very precisely. At fine pressures above The setting of the fine pressure by throttling can be 10 millibars (Valve) in the vacuum line.
- the dosage of more Gas components are carried out additively as in conventional manometric processes by filling up to a specified dosing pressure. Filling with the proportionately largest gas component (main component) is advantageous as last step carried out, this gas component is up to the last dosing pressure, that is the filling pressure of the pressure container with the finished one Gas mixture, filled up.
- main component the proportionately largest gas component
- this gas component is up to the last dosing pressure, that is the filling pressure of the pressure container with the finished one Gas mixture, filled up.
- the measuring container allows small partial pressures due to the precise Pressure measurement also a direct gas metering (additive gas metering) in the Vacuum (i.e. at a pressure below one bar).
- Conditioning and filling the compressed gas tank with the Gas components can be operated simultaneously with several pressurized gas containers (e.g. 1 to 100 pressurized gas containers) at the filling station.
- pressurized gas containers e.g. 1 to 100 pressurized gas containers
- On the stockpiling of mother mixtures as well as complex gravimetric dosing can be dispensed with, so that gas mixtures with gas components are lower Concentration can be made directly.
- a compressed gas cylinder which has been thermally conditioned and filled with a preservation gas (e.g. nitrogen gas) at a pressure of up to 3 bar, is brought to an internal pressure of approximately atmospheric pressure by releasing gas.
- the compressed gas bottle is then evacuated to a pressure of approximately 10 millibars using a vacuum pump (e.g. oil-free membrane pump). This corresponds to a pressure reduction of approx. 2 powers of ten.
- the evacuated compressed gas bottle is flooded with the gas of the secondary component to be fed in to a pressure in the range from 800 to about 1000 millibars.
- the evacuation and flooding with the gas of the secondary component is carried out twice, three times or more, depending on the purity requirement and the composition of the gas mixture.
- the rinsing and the subsequent steps are preferably carried out at room temperature (20 to 25 ° C).
- the compressed gas bottle is now filled with the gas of the secondary component at approximately atmospheric pressure and the inner surface is brought into equilibrium with the gas of the secondary component.
- the compressed gas bottle is now conditioned.
- the actual metering of the secondary component is carried out by evacuation (removal of gas) to the desired fine pressure, which corresponds to the partial pressure of the secondary component in the finished, compressed gas mixture.
- the necessary pressure can be determined theoretically (e.g. using a gas equation such as the ideal gas law or using a calculation model) or empirically (e.g. using gas analyzes). If the fine pressure of the secondary component has been set, the metering of the secondary component is complete. In this way, secondary components such. B.
- the main component of the gas mixture is now pressed onto the final pressure (filling pressure) in the compressed gas bottle, for example 200 bar. This can be done by means of a compressor or by connecting a storage tank of a gas supply (gas of the main component) with higher pressure (e.g. 350 bar).
- the filling with the main component can also be checked gravimetrically.
- the figure shows schematically a measuring container 1 with examples of Measuring devices 2 (2a, 2b, 2c and 2d: temperature sensor) and 3 (3a, 3b: gas line with shut-off valve and pressure gauge, e.g. B. manometer), gas sampling device 4 and connecting piece 7.
- the measuring container is parallel to a second Pressurized gas container 5 (or further pressurized gas containers) arranged.
- the Temperature sensors 2a to 2d are arranged for example in a row Measurement of the temperature profile along the measuring points.
- the temperature measuring points can e.g. B. in the longitudinal direction (here vertically) of a gas cylinder or circular (horizontal here).
- the pressure measuring devices 3a and 3b are advantageously provided with a shut-off valve.
- the gas sampling point 4 is used for taking gas samples for analysis or for online connection of Analysis devices (e.g. mass spectrometer or IR spectrometer).
- Analysis devices e.g. mass spectrometer or IR spectrometer.
- Connection piece 7 is preferably used for separate evacuation of the measuring container for the calibration of vacuum measuring devices.
- Measuring container 1 and compressed gas container 5 are connected via a line to a vacuum pump 6 (arrows show the direction of the Gas flow when applying vacuum) and / or a gas source 6 (z. B. compressor with storage gas containers).
- Another object of the invention is a method for filling Pressurized gas containers with gas or the production of gas mixtures in Pressurized gas containers, whereby a physical or chemical examination by means of a measuring container.
- Physical examinations are e.g. B. pressure or temperature measurement. Chemical tests are e.g. B. Analyzes to determine the Gas composition, which can include physical methods. As Chemical investigations are also analyzes using infrared spectroscopy or mass spectrometry viewed.
