Definitions
- the invention relates to a method for using a target gas flow consisting of pressurized target gas, which is provided by a continuously operated gas separation device, wherein the target gas flow is supplied to a target consumer, who discontinuously decreases the target gas flow, so that at times one of the target consumer not removed
- the invention relates to a system for supplying a
- Target consumer with a pressurized target gas stream and another consumer with another compressed gas comprises a gas separation device, which has a target gas flow for this one
- Target gas stream discontinuously decreasing target consumer provides, so that in the gas separation device results in an excess target gas flow. Furthermore, such a system comprises a compressed gas operated
- Compressor for compressing and feeding the compressed compressed gas in a leading to the other consumer compressed gas line.
- a gas mixture is decomposed into a target gas and an exhaust gas.
- An example of such a gas separation device are systems for air separation, in the English language called "Air Separation Unit” (ASU).
- ASU Air Separation Unit
- cryogenic distillation or low-temperature distillation Used on an industrial scale are air separation plants which operate on the basis of so-called cryogenic distillation or low-temperature distillation ("Linde process"). This process delivers as a target gas
- the "waste gas" of the oxygen extraction process is a gas stream that does not contain the atmospheric nitrogen and other airborne substances in the respective decomposition process
- Systems of this type are used, for example, in the environment of the production of iron or steel melts, but also in many other processes in which pure oxygen is required in larger quantities.
- pure oxygen is required in larger quantities.
- fresh oxygen is blown onto or into the respective melt to eliminate the carbon content of the melt or unwanted iron companion by oxidation.
- the continuous provision of the target gas stream is usually more discontinuous, i. temporally fluctuating demand on the part of
- Target consumer opposite.
- the temporarily not or not completely surplus target gas stream can be cached in buffers in order to be kept ready for demand peaks.
- the cost of such caching and the associated energy losses are considerable.
- Air separation plant ready for blowing oxygen into a blast furnace.
- the blast furnace temporarily or only partially removed excess oxygen flow is passed into a steam generator in order to improve the efficiency of there carried out to generate the required heat combustion of the resulting in the production of pig iron process gases.
- the pressurized nitrogen arising as a waste gas in the air separation process is supplied on the one hand to a coal injection device and, on the other hand, used to support the drive of a gas turbine which drives a generator for generating electrical energy.
- the object has arisen to propose a simplified and suitable for a wider use method and a similarly designed plant, which can be used to save resources in a gas separation plant excess target gases and optionally additionally generated waste gases.
- the invention has to solve this problem, the method specified in claim 1 and proposed in claim 9 system proposed.
- the excess target gas stream is now supplied as a propellant gas to a compressor which compresses another gas and feeds it as compressed gas into a compressed gas line, via which it is supplied to another consumer.
- the drive side of a compressor which compresses a "different gas” different from the target gas flow and feeds it into a general compressed gas line, is supplied with the excess target gas flow.
- "Excess” here includes both the case that the
- Target consumer no target gas from the gas separation device decreases, so the excess target gas flow is equal to the target gas flow provided by the gas separation device, even the case that only a reduced amount of the target gas flow is removed from the target consumer, so only one
- Partial flow of the provided by the gas separation device target gas flow is obtained as an excess target gas flow.
- Gas separation device which provides a target gas flow for a target consumer this discontinuous decreasing target consumer, so that in the gas separation device results in an excess target gas flow, and a compressed gas compressor for compressing and feeding the
- the compressor on the drive side by means of a propellant gas line with an outlet of the
- Gas decomposition device connected via which the excess target gas stream flows as a propellant gas to a propellant gas connection of the compressor.
- excess target gas flow stored energy is used for the compressor and at the same time the excess target gas flow through the compressor is relaxed. In this way, the excess target gas flow, depending on the type of gas it consists of, directly one
- excess target gas is not only used to drive the compressor, but also introduced into the pressure line fed by the compressor.
- the excess target gas stream can be mixed with the other gas to be compressed from the compressor or the compressed gas compressed by the compressor after or during passage through the compressor.
- Target gas flow usually not directly due to the large pressure difference can feed into the compressed gas line, since this would make the proportion of the target gas or the pressure increase caused thereby in the compressed air line too large and there would be a risk of overloading the pressure line system.
- the target gas after it has been vented through the compressor, to the suction side of the compressor so that it mixes with the other gas to be compressed and the gas mixture thus obtained is compressed by the compressor and fed into the compressed gas line.
- a system according to the invention for this purpose may comprise a mixing device which is intended to mix the gas to be introduced into the pressure line target gas or waste gas flow another gas.
- Another way to use the excess target gas stream for compressing a gas and simultaneously feed into the compressed gas line is the choice of a compressor in which a drive gas flow, ie the excess target gas flow, is fed into the respective compressor so that it as a propellant gas the pending on the suction side of the compressor, to entrain gas to be compressed and this compressed as a result of the pressure difference between the propellant and gas to be compressed.
- a drive gas flow ie the excess target gas flow
- the compressor has a suction side, a drive side and an exit side.
- the suction side is the side of the compressor to which the gas to be compressed is supplied.
- the exit side is accordingly, the side of the compressor at which the compressed gas in the compressor flows.
- the side of the compressor is designated, via which the propellant gas is supplied.
- the compressor therefore has two
- Input volume flows to: the supply side as well as the suction side supplied volume flow.
- the compressor compresses the gas supplied on the intake side via the present pressure difference between compressed propellant gas and expanded gas which is in contact with the intake side.
- Air decomposition device is that extracts oxygen from the ambient air as the target gas.
- each of the gas streams obtained by the decomposition (each) is supplied to a target consumer or one or more of these gas streams in the cutting process as
- waste gas stream drops in the cutting process
- the waste gas can be used as a buffer for the time in which due to a large demand at the target consumer is not sufficient for the operation of the compressor excess target gas flow available.
- the generally also with high pressure resulting waste gas stream is thus passed in this embodiment in an accumulator, the waste gas stored there and then used as needed to drive the compressor.
- Another advantage of this embodiment is that can be separated from the air separation process by the memory of the compressor.
- a reservoir may be provided which is connected to an outlet of the gas separation device for a waste gas arising during the gas separation process.
- waste gas should also be usable for the compression of the other gas, this can be accomplished by additionally connecting the reservoir to the drive side of the compressor via a supply line and providing a valve which releases the supply line as needed to supply the compressor by means of the compressor stored in the memory
- the memory can the outlet side with the suction side of the compressor or with the
- Compressed gas line to be connected, if necessary, to mix waste gas in the compressed gas stream to be compressed by the compressor or in the pressurized gas stream compressed by the compressor.
- the interference of target or waste gas into the other gas proves to be particularly resource-saving. This applies in particular if the admixture of the target gas and waste gas takes place simultaneously.
- the gas mixture fed as compressed gas into the compressed gas line, from target gas, waste gas and the other gas may have optimized properties for the respective uses or at least be composed, that despite the admixture of the target gas or waste gas at least no negative impact on the one or the other with the then in the
- the system comprises a mixing device, which is intended to add another gas to the target gas or waste gas stream to be introduced into the pressure line.
- the one gas so for example, only the waste gas or only the excess target gas to mix before or in the compressor, while the other gas is added after the compressor to the compressed gas.
- Fig. 1 shows a system for supplying a target consumer with a
- Fig. 2 is a diagram showing the components of the invention
- the system 1 shown in FIG. 1 for the supply of a target consumer and at least one further consumer is constructed as follows:
- a target gas flow Z consisting of oxygen and high pressure is generated from the ambient air U.
- the decomposition process falls in the gas separation plant 2 in addition from the remaining gas components of the ambient air U, mainly nitrogen, existing waste gas stream A from.
- the generated by the gas separation plant 2 target gas flow Z is via a
- the excess target gas flow Zue is guided via a propellant gas line 5 to the propellant gas inlet 6 of a compressor 7 designed as a gas jet compressor. Trained in a conventional manner, commercially available
- Compressor 7 comprises a mixing chamber 8 with a suction connection 9 and a nozzle device 10, via which the excess target gas flow Zue is introduced into the mixing chamber 8.
- the nozzle device 10 is designed so that the discharged excess target gas flow Zue with high
- Velocity enters the mixing chamber 8, entraining a pending at the suction port 9 other gas G and then in a funnel-shaped tapered, in the flow direction of the entering into the mixing chamber 8 excess target gas flow Zue conical tapered
- Compressor chamber 10a enters, in which the gas mixture formed from the target gas flow Zue and the other gas G is compressed so that it as
- Compressed gas DG is fed into a compressed gas line 11.
- the power of the compressor 7 is not sufficient, it can be arranged in series with a conventional compressor, which makes the possibly still required final compaction of the compressed gas DG to the respective prescribed pressure.
- the compressed gas line 11 supplies various other consumers 12,13,14 with compressed gas DG.
- compressed gas DG is fed into the compressed gas line 11 via a conventional compressor 15.
- gas G is from waste gas AG and ambient air U mixed.
- a mixing device 16 connected to the suction connection 9 is provided, which mixes ambient air U with a waste gas stream A 'in a specific mixing ratio.
- the mixing ratio is adjusted depending on the guided in the compressor 7 excess target gas flow Zue so that on the one hand a sufficiently large compressed gas flow D enters the compressed gas line 11 and on the other hand, as the compressed gas flow D fed into the compressed gas line 11 compressed gas DG has an oxygen content, for example between the Oxygen content of normal air and 30 vol .-%. If a sufficiently large waste gas stream A 'is available, the amount of admixed
- Oxygen content of the compressed gas DG can be set much higher, if the corrosion resistance of the compressed gas line system 11, through which the pressurized gas DG flows, and the supplied with the compressed gas DG consumer 13 allow this.
- the waste gas stream A passes to the mixing device 16 via a line 19 which is connected to an output of a memory 17.
- the storage 17 is fed by the Gaszerlegeeinrtchtung 2 via a supply line 18 with the waste gas stream A. About one to another output of the
- Memory 17 connected supply line 20 may be another or several more consumers 21 are supplied with the waste gas AG. Through the memory 17, the gas separation device 2 is decoupled from the drive side of the compressor 7.
- FIG. 2 illustrates the sequence of the method according to the invention, for example carried out on a system of the type shown in FIG. 1, in a general form.
- a gas mixture U (ambient air) is decomposed in the gas separation device 2 into compressed target gas ZG and waste gas AG.
- the waste gas AG is not blown off unused in the environment, but cached in the memory 17.
- a further consumer 21 can be supplied with waste gas AG.
- waste gas AG is supplied from the memory 17 of the mixing device 16.
