- the gas mixtures are preferably produced according to manometric process in which the individual gas components according to the proportion in the finished gas mixture via your Partial pressures can be filled in the compressed gas tank.
- the production the gas mixtures are made by manual or automatic filling the trailer's compressed gas tank.
- the direct production of the Gas mixtures are primarily suitable for gases without additional Tools or measures lead to homogeneous gas mixtures.
- suitable gases are e.g. B. nitrogen, oxygen, argon.
- gases with non-ideal behavior e.g. B. carbon dioxide or hydrocarbons, in which the manufacture homogeneous gas mixtures is problematic, recommended by special measures or facilities for the formation more homogeneous To worry about gas mixtures.
- the dynamic mixing takes place, for example, with a mixing system, in which the gas components z. B. by pinhole or Mass flow meters are metered into a mixing section.
- a Mixing section can also be implemented, for example, by internals, fillers, Sieve plates in a gas pipe (e.g. with a pipe length of 2 to 5 meters) will be realized.
- the mixing of the gases can, for example, in the Low pressure area or medium pressure area take place, whereby then compresses the gas mixture and into the Compressed gas tank of the trailer is introduced.
- the homogenization the gas mixture can also be made in the pressurized gas containers be when z. B. for a turbulent flow during gas filling is taken care of.
- the manometric method works particularly advantageously with a temperature-compensated pressure detection on the trailer, at least one, preferably all pressurized gas containers with at least one Temperature sensor (e.g. Pt-100) and at least one pressure sensor (e.g. B. Piezo pressure transducer).
- the pressure sensor should at the furthest from the outflow point (gas sampling point) remote location in the compressed gas container (e.g. tube) to avoid measurement errors caused, for example, by a dynamic pressure when filling or a discharge pressure when emptying can be caused.
- a temperature sensor should be near the Pressure sensor may be arranged.
- the following variables and constants are included in the calculation of the current gas filling quantity of the trailer, which are fed to an electronic computing unit (e.g. entered manually or in a program): the total volume V TL (volume; m 3 ) of the compressed gas container of the trailer, the absolute pressure P T in the compressed gas tank of the trailer, the temperature T T in the compressed gas tank of the trailer, the calculated gas volume V TG of the gas or gas mixture in the compressed gas tank of the trailer, the calculated removal volume V AB of the gas or gas mixture in the compressed gas tank of the trailer, calculated total filling volume V IN a gas component or a gas mixture, the molar mass M of a gas component, the density ⁇ of the gas mixture, the general gas constant R and a real gas factor f (p, T) with pressure p and temperature T.
- the electronic computing unit is preferably part of a Control unit for gas metering (filling) and gas delivery.
- the Control unit enables automation of gas dosing and the gas delivery on the trailer.
- A is preferably used as the control unit MSR unit, especially a single-chip board with EPROM. For example, the desired (to be recorded gas quantity to be dispensed).
- a processor determines the Pressure in the compressed gas tank and compares the value (actual value) with the preset (entered) gas volume (setpoint). At a The sampling valve (e.g. pneumatic valve) is used for gas sampling on Trailer closed when the setpoint is reached. After completing the Gas extraction process, the user (operator) can both amount of gas delivered as well as the amount of residual gas on a display read from the trailer.
- the trailer is z. B. with a nitrogen tube and an empty or evacuated tube equipped.
- the nitrogen tube is a pressurized gas container filled with nitrogen. This can be used for flushing damaged pipes or as Back pressure medium can be used. In addition, at Use the residual pressure valve as nitrogen Pneumatic control air from the MCR technology can be used. Furthermore, the nitrogen is used to purge the plant components used can be used after fumigation.
- the empty or evacuated tube can be half of the damage Absorb the amount of gas from a defective tube and thus help to repair the damage limit.
- the trailer is usually equipped with individually lockable tubes.
- the valve position of the shut-off valve on the trailer is preferred clearly recognizable by an opening indicator at a distance.
- valve 21 After valve 21 is closed, the gas is released via valves 22 and 23 drained, that is, it is flushed with gas from gas source 1.
- the pressure gas containers (tubes) 9 are relieved and evacuated, 10 and 11 by opening valves 13, 14, 15, 17, 16, 18, 22 and 23 (Relief to atmospheric pressure), closing of valve 23, opening of the valve 24 and evacuation of the tubes with the help of the vacuum pump 28 and closing the valves 22 and 24.
- the desired gas dosing pressure With the help of the valve 25, 33 or 50 the desired gas dosing pressure is set.
- the pressure can be read from 38 to 10 bar on the manometer. With a print ⁇ of more than 10 bar, the valve 4 closes automatically, so that the Pressure transducer 38 can not be destroyed.
