Definitions
- the invention relates to a method for recirculating exhaust gas from a gas turbine with subsequent waste heat boiler, wherein this exhaust gas is metered into the supply air flow of a gas turbine, so that the temperature and the composition of the exhaust gas can be controlled, and in this way highly concentrated Carbon dioxide (C0 2 ) is injected, which is injectable into a deposit, so that the balance for carbon dioxide for the entire process can be kept low or is negligible.
- the metered recirculation of the exhaust gas, the temperature in the gas turbine can be lowered and increase the proportion of carbon dioxide in the exhaust gas significantly, so that after combustion and heat exchange, a gas scrubbing is possible, and on the one hand the carbon dioxide can be recovered and on the other hand, the proportion of free oxygen in the exhaust gas can be lowered.
- an oxygen-enriched gas is fed with a fuel gas into a gas turbine for combustion, then diluted with exhaust gas so that the temperature can be kept low despite oxygen enrichment, and highly concentrated carbon dioxide is obtained after combustion and heat exchange.
- gases can be used, which are suitable for driving gas turbines, which are ultimately gases that can be introduced into the gas space of a turbine, and produce no corrosive residues or combustion products during combustion.
- gases for example, natural gas, refinery gases, biogas or synthesis gas.
- refinery gases are, in particular, those gases which are produced during the processing of liquid fossil fuels, such as butane, hydrogen-containing gases or liquefied petroleum gas, also referred to as LPG ("Liquefied Petroleum Gas").
- LPG Liquefied Petroleum Gas
- One method of producing synthesis gas is, for example, coal gasification, in which a finely ground carbonaceous fuel is gasified with an oxygen-containing gas in an entrainment gasification process.
- the synthesis gas thus obtained can be used in the drive of gas turbines by combustion.
- a gas scrubbing is usually carried out prior to combustion, so that the fuel gas produced during combustion no corrosive gases and economic life of the gas turbine can be achieved.
- the temperature at the combustion of fuel gases in gas turbines is usually up to 2200 ° C.
- the hot exhaust gas is passed after combustion in a waste heat boiler, so that the sensible heat of the exhaust gas can be used to obtain steam.
- the combustion produces carbon dioxide (C0 2 ) and water (H 2 0), so that the gas contains only nitrogen (N 2 ) in addition to these gases, if the fuel gas is subjected to gas purification before combustion. If pure oxygen is used for combustion, the exhaust gas contains practically only carbon dioxide and water.
- Carbon dioxide is a greenhouse gas, which contributes to the warming of the earth's atmosphere. For this reason, many countries are anxious to keep the emission of carbon dioxide in the earth's atmosphere low. It is therefore technically possible to design processes in such a way that they generate less or no carbon dioxide from the outset. Since the use of pure hydrogen as a fuel gas is usually not economical, it is endeavored to provide processes with little or negligible emissions of carbon dioxide, which is usually done by a gas scrubber. The carbon dioxide is washed out by absorbing the carbon dioxide from the combustion gases with an absorbing solvent. The carbon dioxide is then obtained in the regeneration of the absorbing solvent.
- a starting point for this is to keep the composition of the exhaust gas from a gas turbine so that a gas scrubbing causes as little effort.
- the oxygen content of the exhaust gas to be cleaned should be as low as possible, since oxygen impairs the functionality of most absorbing solvents.
- Many absorbing solvents used to scrub carbon dioxide contain amine groups that react with oxygen. For this reason, the composition of the exhaust gas of a gas turbine is of importance for the economy of the entire process.
- the present invention solves this object by a method which exists in two embodiments, which are to a certain extent edge regions of a main process step, this main process step being a partial flow of the cooled exhaust gas exiting the waste heat boiler after the heat exchange in to meter in the combustion air to the gas turbine so that an increased amount of carbon dioxide is obtained, and after combustion a heat exchange for recovery the heat energy and a gas scrubbing is performed, in which carbon dioxide (C0 2 ) is obtained.
- This procedure so to speak, constitutes an edge region, the other edge region being to avoid gas scrubbing in which pure oxygen is used as the oxidant in the gas turbine.
- pure oxygen is used as the oxidant in the gas turbine.
- the metered addition of the exhaust gas into the combustion air of the gas turbine is carried out so that as much exhaust gas is returned, but combustion is still possible without problems.
- This is preferably controlled by means of measuring parameters, wherein a measuring parameter consists in the measurement of the combustion temperature in the gas turbine.
- a measuring parameter consists in the measurement of the combustion temperature in the gas turbine.
- the carbon dioxide is preferably obtained in highly concentrated form. This can be pure or technically pure, but can ultimately be obtained in any concentration.
- Claimed is in particular a method for the metered return of cooled exhaust gas from the waste heat boiler of a gas turbine by burning a combustion gas suitable for combustion with an oxygen-containing gas in a gas turbine, so that mechanical energy is obtained, and the exhaust gas in a waste heat boiler indirect heat exchange water evaporates, so that hot steam is generated, and which is characterized in that a partial flow of the cooled exhaust gas is discharged after exiting the waste heat boiler in the combustion air to the gas turbine, which is passed into the gas turbine for combustion, and another partial flow the cooled exhaust gas is discharged after exiting the waste heat boiler in a gas scrubbing for the absorption of acidic gases, from which carbon dioxide (C0 2 ) is recovered.
- Also claimed is a method for metered recirculation of cooled exhaust gas from the waste heat boiler of a gas turbine by burning a combustion gas suitable for combustion with an oxygen-containing gas in a gas turbine with an oxygen-enriched gas, so that mechanical energy is recovered, and the exhaust gas evaporates in a waste heat boiler by indirect heat exchange water, so that hot steam is generated, which is characterized in that a partial flow of the cooled exhaust gas is metered after exiting the waste heat boiler in the combustion air to the gas turbine, and the other partial flow is cooled, the water condenses out and carbon dioxide (C0 2 ) is recovered ,
- Methods for using gas turbines with a return of partial exhaust gas streams are known in principle from EP0453059B1 or JP4116232A. However, these do not contain carbon dioxide recovery and do not meter the recirculated exhaust gas.
- the oxygen-enriched gas is preferably taken from an air separation plant. This can also be provided by a pressure swing absorption. Ultimately, the oxygen-enriched gas can be generated arbitrarily.
- an oxygen-enriched gas as the oxidant in the gas turbine, the proportion of carbon dioxide after combustion increases and the content of nitrogen in the exhaust gas decreases. Gas scrubbing is simplified because the gas balance of the nitrogen during gas scrubbing is low. However, this is still necessary if the nitrogen content in the carbon dioxide of the exhaust gas is technically available.
- a partial stream of the cooled exhaust gas after exiting the waste heat boiler, is passed into a gas scrubber to absorb acid gases, from which carbon dioxide (CO 2 ) is recovered.
- CO 2 carbon dioxide
- the oxygen-enriched gas is pure oxygen, wherein the other partial stream obtained is cooled, so that the water condenses out and carbon dioxide (C0 2 ) is recovered.
- the carbon dioxide can then, as in the other embodiments, be compressed and injected into the deposit.
- pure oxygen then the nitrogen content in the exhaust gas falls away completely. Gas washing is then no longer necessary.
- the fuel gas for the gas turbine may be of any kind, as long as it is suitable for combustion in a gas turbine. It is important, above all, that this does not produce any corrosive components during combustion, affected by the turbine could be drawn.
- the fuel gas is synthesis gas.
- the synthesis gas is a synthesis gas derived from a coal gasification reaction in which a finely ground carbonaceous fuel is gasified with an oxygen-containing gas in an air flow reaction.
- Coal gasification reactions to produce synthesis gas are well known in the art, an exemplary embodiment of a coal gasification reaction for the recovery of synthesis gas is EP0616022B1.
- the fuel gas may also be natural gas. This can be purified prior to combustion in a gas turbine so that corrosive components and in particular sulfur compounds are removed. An example of gas purification of natural gas is the ⁇ 92090 ⁇ 1. The purified natural gas is then used to fire the gas turbine.
- the fuel gas is a refinery gas.
- LPG Liquified Petroleum Gas
- propanes and butanes and hydrogen which in an exemplary embodiment can be admixed with the combustion gas of a gas turbine if the process according to the invention is to be used.
- the fuel gas is biogas.
- This is a fuel gas, which is formed from biological raw materials, including for example wood, cattle manure, straw, or grasses. These can be obtained by way of example by fermentation, but also by way of example by gasification.
- the resulting carbon dioxide can then be compressed and injected into a carbon dioxide deposit. Although this is the preferred embodiment within the scope of the invention, it is always conceivable to use the carbon dioxide for further purposes or to use a partial flow for reinjection into a reservoir.
- the metering of the cooled and recirculated exhaust gas from a gas turbine with waste heat boiler is preferably carried out on the basis of measured values. This is typically the temperature of the exhaust gas from the gas turbine immediately behind the gas turbine and before entering the waste heat boiler. In one embodiment of the invention, therefore, the proportion of the recirculated gas stream from the waste heat boiler and the amount of the substream metered into the gas turbine are controlled by measured values of the temperature of the exhaust gas from the gas turbine.
- gas turbine mechanical energy is generated, which can be used arbitrarily. This can be used as an example for generating electricity.
- the heat energy from the waste heat boiler can be used arbitrarily. This is preferably used to generate steam and via a turbine to generate electricity.
- the invention has the advantage of providing purified carbon dioxide (CO 2 ) from a gas turbine for compression and re-injection into a deposit, the economics of the process being improved by having a partial flow of the exhaust gas from the gas turbine in the gas flow direction behind the waste heat boiler is returned to the gas turbine and metered into the combustion air, so that the proportion of carbon dioxide in the exhaust gas is increased so that either a gas scrubbing to remove the carbon dioxide from the exhaust gas can be carried out in an economical manner or ideally completely eliminated when using an oxygen-enriched oxidizing agent ,
- FIG.1 shows the inventive method in which a first partial flow of the exhaust gas is returned behind the waste heat boiler and is metered into the gas turbine, and the second partial flow of the exhaust gas behind the waste heat boiler of a gas scrubber is supplied for carbon dioxide.
- 2 shows the inventive method in which a first partial flow of the exhaust gas is returned behind the waste heat boiler and is metered into the gas turbine, which is heated with pure oxygen as the oxidant, and condensed the second partial flow of the exhaust gas behind the waste heat boiler and as a ner carbon dioxide stream is used.
- the exhaust gas (5) from the gas turbine (1) is supplied to a heat boiler (6), in which the exhaust gas (5) its sensible heat via indirect heat exchange to supplied water (6a) and thereby steam (6b) is obtained.
- a partial flow of the exhaust gas (5a) is returned and metered via the mixing valve (4) in the combustion air (3). This increases the proportion of carbon dioxide in the exhaust gas (5).
- the temperature of the combustion gas and exhaust gas (5) is lowered, which is gentle on the gas turbine (1).
- the other partial stream of the exhaust gas (5b) is added to a gas scrubber (7) with an absorbing solvent in which the carbon dioxide (C0 2 , 8) is washed out to obtain a carbon dioxide-free residual gas (7a).
- This is recovered in the regeneration (9) of the solvent and can be compressed and injected into a reservoir.
- the metering of the return (5a) takes place via the control of the mixing valve (4) on the basis of the measurement of the temperature of the exhaust gas (5) with a measuring sensor (10) and is controlled by a computer (10a).
- gas turbine (1) which with a hydrocarbon-containing fuel gas (2) and pure oxygen (11) from an air separation plant (11a), which outlet air (3a) in oxygen (11) and the remaining components ( 11b), (11a) is heated, via a mixing valve (4) pure oxygen (11) is added as the oxidant, and by the combustion in the gas turbine (1) mechanical energy is obtained.
- the exhaust gas (5) from the gas turbine (1) is supplied to a waste heat boiler, in which the exhaust gas (5) its sensible heat via indirect heat exchange to supplied water (6a) and thereby steam (6b) is obtained.
- a partial flow of the exhaust gas (5a) is returned and metered via the mixing valve (4) in the oxygen (11).
- the exhaust gas (5) contains only water (H 2 0) and carbon dioxide (C0 2 ).
- the second part stream (5b) of the cooled exhaust gas is further cooled (5c) for condensation, so that after separation of the condensed water (5d) practically pure carbon dioxide (8) is obtained.
- the temperature of the combustion gas and exhaust gas (5) is lowered by the return, which is gentle on the gas turbine (1).
- the carbon dioxide (8) can be compressed and injected into a reservoir.
- the metering of the return takes place via the control of the mixing valve (4) on the basis of the measurement of the temperature of the exhaust gas (5) via a measuring sensor (10) and is controlled by a computer (10a).
