Definitions
- the invention relates to a method for producing gas mixtures.
- gas mixtures have been in individual compressed gas cylinders (e.g. 50 Liter compressed gas cylinders) or bundles of compressed gas cylinders.
- the invention has for its object a method for manufacturing to provide gas mixtures in large quantities, especially one Process for the provision of gas mixtures on site at the Consumer.
- the task was solved by a process for the production of Gas mixtures, characterized in that the gas mixture in the Pressurized gas containers of a pressurized gas cylinder truck manufactured directly or the gas mixture in one of the pressurized gas containers Compressed gas cylinder wagon upstream mixing device continuously manufactured and in the compressed gas tank of the Pressurized gas cylinder wagon are directed.
- the invention thus relates to a method with the features of claim 1.
- Advantageous refinements are the subject of Claims 2 to 5.
- the invention enables the provision of homogeneous, stable, in Specialized companies producing gas mixtures in large quantities every place.
- Pressurized gas cylinder wagons also called battery vehicles or trailers, are vehicles (for road or rail transport) with a larger number (e.g. 18 or 49) of interconnected pressurized gas containers.
- Pressurized gas containers are e.g. B. tubes or large bottles.
- the compressed gas tanks have z. B. gas capacity of 1000 to 4000 m 3 at 200 bar.
- the pressurized gas containers of the pressurized gas cylinder trolley are preferably individually lockable.
- the pressurized gas cylinder truck consists, for. B. from a truck chassis, on which a suitable number of compressed gas cylinders as a compressed gas container is installed.
- the compressed gas cylinders whose geometric volume in usually amounts to 50 to 1500 liters, can be both permanently installed, as well also by battery with quick couplings to the chassis be connected.
- the number of compressed gas cylinders depends on the Material of the container and the density of the gas mixture; the permissible total weight limits the number of compressed gas cylinders.
- pressurized gas cylinder wagons with several pressurized gas containers are the Pressurized gas tanks usually with one another via pipes connected and lockable individually or in groups.
- the design of the piping meets the special requirements of Gas mixture production bill. From the filling and dispensing valve the pipelines branch out towards the compressed gas tanks such that the pressure loss on the way between the main valve and compressed gas tank is almost identical for all compressed gas tanks.
- gas sources provided.
- gas sources such. B. compressed gas cylinders, Compressed gas cylinder bundles, gas storage tanks, containers or tanks with refrigerated gases or gas supply systems (with tank, Evaporator and compressor).
- Gas sources can also be devices for gas generation like electrolysis cells for the generation of Chlorine gas or chemical reactors. With gas components with Low vapor pressure is recommended when using compressed gases in compressed gas cylinders a bottle heater.
- the gas mixtures are produced, for example, according to static manometric process in which the individual Gas components with the partial pressure corresponding to the proportion in finished gas mixture can be filled in the pressure gas container.
- the gas mixtures are advantageously produced after dynamic volumetric process.
- different volume or mass flows of the gas components in merged into a mixing device.
- a Pressure reducer and one flow meter required for each gas type.
- Manometric, gravimetric and volumetric gas metering can advantageously be combined to produce the gas mixture become.
- two secondary gas components can follow the volumetric process and the main component of the Gas mixture can be dosed according to the manometric method.
- the dynamic-volumetric method is characterized in that all gas components continuously in a mixing device, e.g. B. Mixing chamber or mixing section, flow. Contains a mixing section for example, packing or internals, which are used for swirling the Gases. The ratio of continuously measured and regulated material flows correspond to the desired gas mixture composition.
- the static volumetric method is advantageous if one faster filling of the compressed gas cylinder wagon should take place or for gas components that require complicated handling.
- the static-volumetric method is characterized in that a premix is first produced in a mixing container as a mixing device. Such a procedure enables all time-consuming production steps to be carried out without a compressed gas cylinder wagon being connected to the filling device, which drastically reduces the downtimes. This advantage is particularly useful when dosing secondary gas components that are liquefied under pressure and can only be dosed slowly due to icing (eg PH 3 ).
- the static-volumetric method in particular in the production of gas mixtures with more than two secondary gas components or gas components with a small proportion in the gas mixture, it is advantageous first of all to pre-mix the secondary gas components in a mixing container, e.g. B. generates a mixing container with a geometric volume of up to 10 m 3 .
- the premix is homogenized, for example, by pumping through an injector, generating a convection flow by heating or a stirring device.
- the premix reaches the compressed gas cylinder wagon by overflow or with the aid of a compressor.
- the main gas component is dosed manometrically.
- Fig. 1 the production of a gas mixture with three is an example Gas components according to the dynamic volumetric process shown.
- the gas components are in compressed gas containers, the Pressurized gas sources 1, 2 and 3 provided.
- the compressed gases are removed via the pressure reducers 4, 5 and 6, respectively.
- the Gas quantity of the gas components is controlled individually via the Valves 11, 12 and 13 metered into the mixing chamber 14.
- the Mixing ratio of the gas components is controlled by the Valves 11, 12 and 13 by means of a control unit 7 during the Process kept constant.
- the composition of the Gas mixture is analyzed with the analysis unit 15 (e.g. Mass spectrometer) checked.
- the continuously formed Gas mixture is continuously fed into a buffer container 16 and compressed by a compressor 17.
- the compressed gas mixture is the hose 18 into the compressed gas container (tubes) of the Pressurized gas cylinder car 20 filled.
- Fig. 2 shows an example of the production of a binary gas mixture according to the static-volumetric method.
- the secondary gas components are metered into the mixing container 27 one after the other.
- Pressurized gas bottles and pressurized gas bottle bundles serve at Auxiliary gas components with a small proportion as compressed gas source 2.
- the Quantity dosing is done with the weighing device 21.
- Second gas components with a large proportion are manometric by the Hand valve 28 metered from another gas source. After completion of the Dosing of all secondary gas components homogenizes one of the already described devices (mixing device) the premix.
- the premix flows, possibly supported by a compressor, via the connecting hose 18 into the compressed gas container (Tubes) of the gas cylinder truck.
- the Main component manometrically from a correspondingly powerful Gas source metered in.
