The scope of the invention

The present invention relates to the oxygen separator and method of separating oxygen, which uses a ceramic membrane ionic conductivity for selection Kislichenko membrane to filter oxygen is placed within the channel, which is either directly connected with the production of the gas turbine, or connected with the combustion chamber of a gas turbine to receive air heated by burning fuel.

The background to the invention

Separation of oxygen from the heated flow of high pressure air produced by the gas turbines, can be easily made with ceramic membranes ionic conductivity for the selection of oxygen, because the gas turbine produces more air with high temperature than is required to maintain combustion in the turbine. In fact, there is sufficient excess air at high temperature to give the ability to extract sufficient oxygen as a byproduct.

There are a number of references in the prior art, which are described combining gas turbines with oxygen separators, which use ceramic membrane ionic conductivity for the selection of oxygen (hereinafter referred to in the description and claims as “ceramic membranes for selection of oxygen”). For example, J. D. Wright and others in the “Advanced membrane for separating oxygen”, pp. 33-61 (1990), describe the Association, in which compressed air is indirectly heating passes through the delay side of the separator, where part of contained oxygen passes to the transmitting side under the action of the pressure generated by ceramic membrane ionic conductivity. The remaining part of the oxygen-depleted, is heated in heater with fire heating to a temperature of turbine inlet and is then expanded in the turbine to produce energy. Heater fire saloon contains a coil for heat exchange to heat the feed to the separator. This Association is shown in U.S. patent No. 5516359. In this patent, the air is compressed to high pressure and heated to the operating temperature of the membrane through the combustion chamber or through indirect heat exchange. The heated compressed air is then applied to the retarding side of the membrane separator, which removes oxygen from air. The remainder of depleted oxygen, optionally heated to a temperature of turbine inlet through direct combustion before it expands in the turbine to produce energy. In U.S. patent No. 5562754 describes the introduction of steam remaining in the stream depleted in oxygen, as a replacement for the separated oxygen, and also the use of steam as the washing gas permeable side of the membrane, talkatora particularly suitable for upgrading existing installations. In one embodiment, only a portion of the compressed air stream is processed in a membrane separator. The resulting remaining portion of the oxygen-depleted connected with the flow that bypasses the separator prior to expansion in the turbine. Another option provides for a separate air compressor for submission to the membrane separator. The remaining part of the oxygen-depleted, is heated in two-stage combustion chamber and is then expanded in the turbine.

U.S. patent 5865878 introduces various concepts of Association of ceramic membranes to filter oxygen from the gas turbine, in which the reagents as steam and natural gas, are introduced into the permeable side of the membrane separator, to respond to the last oxygen for the formation of desired products, such as syngas.

In U.S. patent 5820654 describes a method and apparatus in which oxygen is extracted from the heated oxygen-containing stream through a ceramic membrane for selection of oxygen in which the oxygen is cooled by indirect heat exchange with a part of the entering air flow. The Department and the cooling gas are combined in one device, in order to maximize the use of conventional hardened require the use of auxiliary equipment, such as heat exchangers and systems of long lines, for extracting air and re-introduction of air depleted in oxygen. As you can appreciate, such equipment and pipelines increase the complexity and cost of the business combination of the membrane separator and the gas turbine. In addition, the pipelines of large length to cause the differential pressure and difficulties in providing uniform flow distribution in the separator.

As will be described, the present invention provides traps oxygen and the ways in which ceramic membranes for selection of oxygen, which is designed for Association with a gas turbine without the use of long lines. As a result, the pressure drop associated with handling a large flow of air between the components of the installation are minimized, and the problem of flow distribution is reduced.

Summary of the invention

In one aspect of the present invention proposed an oxygen separator for separating oxygen from the heated gas containing oxygen is discharged from the expander of the hot gas generator of a gas turbine is used to drive the power turbine. It should be noted that the generator hot is R. The release of the extender has both high pressure and temperature, and can be used to drive the power turbine, which is located on the shaft that is separate from the shaft of the compressor-expander. Usually the combination of the hot gas generator power turbine is a structure converted aircraft engine.

Many ceramic membranes for selection of oxygen provided to extract oxygen from the heated gas. Such membranes are mounted within the channel so that the oxygen is separated from the heated gas containing oxygen. The separated oxygen is assembled inside the ceramic membranes for selection of oxygen, and the outer gas stream depleted in oxygen, is formed inside the channel. Means are provided for extracting oxygen from the ceramic membranes for screening kit release from the expander power turbine, the Association is carried out simply and without significant pressure drop when removing the heated gas containing oxygen from the expander, and the re-introduction of gas depleted in oxygen, in the power turbine. Further, if the oxygen separators are not United as stated above, such a high differential pressure between about 3.45 bar and approximately 5.52 bar, often required at the point of re-injection to achieve a uniform distribution. This is inefficient, because it requires a much greater degree of compression than the first case.

Another Association is the Association with combustion chambers of gas turbines industrial type. The extender of these units operates as an air compressor, and combine other consumers, such as generators or compressors process. The release of the extender is usually under a pressure close to atmospheric. This aspect of the present invention provides an oxygen separator for separating oxygen from compressed air passing into the combustion chamber of the gas turbine. An elongated channel open from opposite ends, is configured such that it is connected to the combustion chamber of a gas turbine to generate egret, and to release the gas depleted in oxygen.

Another suitable alternative hallmark of the oxygen separator of the present invention with the use of ceramic membranes in tubular form is to create a screen surrounding ceramic membranes for selection of oxygen. Inlet pipe for additional cold air passes through the channel and is connected to the screen for introducing cooling air to cool the oxygen produced inside the ceramic membranes for selection of oxygen, and the design on which they are supported ceramic membranes for selection of oxygen. Alternatively, many tubular fittings can be mounted inside the ceramic membranes for selection of oxygen to create a narrow annular flow, and thus to improve the heat-transfer coefficients film on the side where the oxygen goes inside the ceramic membranes for selection of oxygen.

In any type of Association, considered in the present invention, a ceramic membrane to filter oxygen from the tube-like configuration can be mounted inside the channel through the connection tube plate which is connected to the channel. Means for extracting oxygen can be formed by a plate collector, which is connected with the tube sheet and having at least one opening to allow passage of oxygen from otkryivay with the specified plate collector, which covers at least one opening, and outlet piping connected to the cover and passes through the channel.

According to another additional aspect of the present invention, the channel may be formed of at least two sections and plate collector, which is connected at least with one or two sections, and tube sheet connected to the other of the two sections.

With this purpose, at least one hole of said plate collector can contain coaxial radial rows of holes. Pipe rack, plate collector and the cap may have an annular configuration to form them in coaxial concentric Central inner hole. The fitting can be connected to the tube plate, and b the location, to ceramic membranes for selection of oxygen in tubular form below to stream after the input socket for additional cold air of the specified channel.

According to another aspect of the present invention provides a method of separating oxygen from the heated gas containing oxygen is produced from the output of the hot gas generator of a gas turbine is used to drive the power turbine. In accordance with this method, the heated gas containing oxygen, is taken at one end of the channel mounted directly between the expander of the hot gas generator of the gas turbine and the power turbine, which is operatively linked. Oxygen is extracted from the heated gas containing oxygen, through the penetration of oxygen ions through many ceramic membranes for selection of oxygen. Ceramic membranes for selection of oxygen are mounted within the channel so that the oxygen is separated from the heated gas containing oxygen, by means of penetration. Past oxygen going inside ceramic membranes for selection of oxygen, and the outer gas stream depleted in oxygen, is formed inside the channel. Gas depleted in oxygen, is produced with the opposite of the other aspect of the present invention provides a method for separating oxygen from compressed air, coming into the combustion chamber of the gas turbine. In accordance with this method, compressed air is heated by burning fuel to form a hot gas containing oxygen. The heated gas containing oxygen, is received inside the elongated channel that is open on opposite ends and connected to the combustion chamber of the gas turbine. Oxygen is extracted from the heated gas containing oxygen, through the penetration of oxygen ions through many ceramic membranes for selection of oxygen, having a closed end and opposing open ends. Ceramic membranes for selection of oxygen are mounted within the channel so that the oxygen is separated from the heated gas containing oxygen. The separated oxygen is assembled inside the ceramic membranes for selection of oxygen, and the outer gas stream depleted in oxygen, is formed inside the channel.

Detailed description

In Fig.1 depicts the Association of the generator 1 hot gas of the gas turbine and the separator 2 of oxygen in accordance with the present invention. In this combination, the heated gas containing oxygen is obtained from the generator 1 hot gas of the gas turbine is fed into the separator 2 oxygen, which contains ceramic membranes for selection of oxygen to separate the oxygen from the heated gas containing oxygen to obtain a gas depleted in oxygen, which is used to drive the power turbine 3. Power turbine 3, as shown, may be used to drive an electric generator 4.

Generator 1 hot gas of a gas turbine equipped with a compressor 10, to compress the air. The compressor 10 generally has no intermediate cooling, although it may be a multi-stage machine with intermediate cooling. Fuel is burnt in the combustion chamber or the combustion chamber 11 to heat the compressed air and thus to form the compressed and heated air, which expands to split timing is agrey gas “A”, containing oxygen stream is produced from the generator 1 hot gas of a gas turbine has a pressure in the range between about a 4.83 bar and about 6.9 bar, and the oxygen content in the range between 12% and about 17%. The temperature of the heated gas “A”, containing oxygen, is in the range between approximately 800With and about 900With and therefore very suitable for further processing in ceramic membranes for selection of oxygen to separate the oxygen to produce a gas, depleted in oxygen. The separated oxygen can be retrieved as a stream 14 of the obtained oxygen. Membranes are a type of membranes with ion migration, which may contain material from a mixed ionic and electronic conductivity, or a multiphase mixture of materials with ionic and electronic conductivity.

In certain cases, the advantage is the use of materials that have only ionic conductivity, and therefore require an external electrical energy to create a driving force for the migration of oxygen ions. As will be described, although the present invention is illustrated with reference to such membranes, which have a tubular shape and in Kotor. zvezdnye membrane in the form of flat plates are also possible, and there is a tendency that, with the exception of those cases where some form of membrane is agreed, declared or illustrated, the present invention is not limited to any particular configuration of the membrane.

The fuel introduced into the combustion chamber 11, can be any stream of hydrocarbon or carbon-containing gas or liquid. Usually it is a natural gas or syngas, if it is available. In the case of synthetic gas, the ratio of hydrogen to carbon monoxide may be in the range between about 0.5 and about 2.0 to. Syngas is the best fuel, as it gives the possibility to generate about 25% more heat per 1 mol of oxygen reacting in the combustion chamber. This leads to somewhat higher oxygen concentration or partial pressure of oxygen at the entrance to the ceramic membrane ionic conductivity for the selection of oxygen, which allows higher pressure of the extracted oxygen, a smaller area of the membrane or greater extraction of oxygen.

Additionally in Fig.2 shows an additional modification of the process in the main, as shown in Fig.1. Stream tiblets heat for example, to couple received in the stream 15 from the waste heat boiler waste heat, and/or to the stream 16 additional supplied compressed air received through the secondary compressor 17 to increase the flow produced from the generator 1 hot gas of the gas turbine. In this respect, the use of such a stream of 16 additional compressed feed air is especially advisable in the case of modification. Such a flow of 16 additional compressed feed air is usually at least equal to the volume of the number of extracted oxygen at a pressure above the pressure in the main flow. This ensures efficient heat dissipation for cooling stream 14 received oxygen. It also allows the use of an effective multi-stage industrial air compressor with intermediate cooling, which results in less power to compress air in comparison with the case when all the air is squeezed by a single-stage compressor of the gas generator without intermediate cooling. In addition, it reduces the mismatch between the expander and the compressor of the gas generator in the modified constructions or installations.

As shown, the thread 16 of the DOP is to be added to the air flow between the compressor 10 and the combustion chamber 11. Alternatively, as will be described, such a stream may be introduced into the separator 2 oxygen for additional cooling.

Usually when the value of partial pressure of oxygen on the delay side of the membrane ionic conductivity for the selection of oxygen required to produce the extraction of oxygen at a pressure substantially below atmospheric to maintain a positive driving force. Such a low pressure extraction can be avoided by using a membrane with an electric drive, in which the electrodes are inserted into the electrolyte only ionic conductivity, and the electric potential generated by an external energy source in a known manner to result in the movement of oxygen ions from the cathode, or detaining hand, to the anode, or transmitting party.

Another way to avoid a vacuum is generating steam, which is used to purge transmissive side of the ceramic membrane ionic conductivity for the selection of oxygen. In the typical conditions of the hot gas produced from the generator 1 hot gas of the gas turbine (pressure equal to approximately 6,21 bar, the oxygen content of approximately 15%, and the extraction of oxygen to 33% of its content in the air), required content is use atmospheric partial pressure of oxygen, low enough to avoid reduction relations in the partial pressure of a driving force. Through disposable heat oxygen can produce about half of the required steam, the residue may be produced in the HRSG waste heat using disposable heat producing power turbine. This is shown in Fig.2 as stream 15 from the waste heat boiler waste heat. Alternatively, if it is inconvenient or uneconomical to produce additional steam, the amount of steam generated by extracting heat from the stream of received oxygen, will allow you to work with an average vacuum of about 0,827 bar, which is comparable with the size of about 0,24 bar for the case without blowing.

The amount of steam contained in the stream 14 of the obtained oxygen can be separated by condensation in the condenser 18 and the separation of the condensate in separator 19 water, leaving a stream of pure oxygen, saturated with moisture. If required, the remainder containing water vapor can be removed in operations downstream through devices such as membrane or adsorption dryers. Thread 14 of the obtained oxygen can be compressed to the pressure supply to the compressor 20 oxygen.

Although not shown in% the ü oxygen 2, can be converted to synthetic gas generators. In this case, the fuel and possibly gas recycling must be added to a couple of stream 15 from the waste heat boiler waste heat to form the combined stream. The combined stream then is fed to the anode ceramic membranes for selection of oxygen, which must be filled by the respective reforming catalyst, for example Nickel. Past oxygen to react with the fuel, steam and gas recycling, for example carbon dioxide in the combined partial oxidation reformer to produce the synthetic gas. These reactions must provide a high driving force for oxygen transport.

The outer walls 136 of type disk or toroid may be provided to increase the heat-transfer coefficients film on the side of the cooling air within the heat transfer section, and a Central partition wall 138 of the type of disc and doughnut can be provided to improve the mass transfer between the hot air and ceramic membranes 36 for selection of oxygen in the section for the Department.

In Fig.7 shows the Association of the separator 5 of the oxygen combined with shows in an enlarged scale industrial gas turbine 6 of the type used in the IGCC process. The gas turbine 6 is supplied by a compressor 146, which is driven by the expander 148. Fuel is burnt in the combustion chambers or furnaces 150 to heat the compressed air received from the compressor 146 to form the compressed and heated air to drive extender 148. The extender 148 typically produces more work on the shaft, which is used to generate electricity through a generator or compressed gas through a separate compressor.

The separators 5 oxygen connected with the combustion chamber 150. Pre-combustion chamber 7 connected to the separator 5 oxygen, have the injectors 151 fuel DL is oroda in the separators 5 oxygen. The air supplied to the pre-combustion chamber 7, is a compressed air passing from the compressor 146 along the circular passages 152 in the combustion chamber 150 and the circular passages 153 in the separator 5 oxygen, or a combination of air generated from the release of the compressor 146, and the air treated in a separate compressor. Air from a separate compressor can be added directly into the annular passages 152 through the nozzle 154. Although not shown, such separately compressed air can be added directly into the pre-combustion chamber 7.

From 5 to 20% of the air compressed in the compressor 146, goes straight to the extender 148 for cooling, and from 10 to about 95% of the air compressed in the compressor 146, takes place in pre-combustion chamber 7. The rest of the air is supplied directly into the combustion chamber 150. In the separation of oxygen in the separator 5 of the oxygen it turns out the gas, depleted in oxygen, which is introduced into the combustion chamber 150. Although not shown, the separators 5 oxygen can be connected between the combustion chambers 150 and the gas turbine 6 in order to receive the heated gas “And” oxygen-containing, directly from the combustion chamber 150. In this case, the gas In oxygen-depleted, will be directly vyey is a converted design of the separator 2’’ in Fig.6. The internal node of the separator 5 is virtually identical to the node separator 2’’ with modifications for gas turbine 6. The separator 5 oxygen differs from separator 2’’ add annular passage 153 formed between the channel walls 83 and outer channel 156, and replacement of section 84 of the channel 83 preliminary combustion chamber 7. Additionally, the speaker output pipeline 128’ and protruding inlet pipe 134’ for cold air to pass into the pre-combustion chamber 7 and the outer channel 156. It should be noted that the possible design of the present invention, in which the pre-combustion chamber 7 is formed by a separate device, which, being connected to the oxygen separator, is not one with him, as shown in the design of the separator 5 of the oxygen.

The outer channel 156 is attached to the transition portion 157 of the channel leading from the gas turbine 6 through the flanges 158 and 159. Increased plate 118’ collection and increased tubular grille 116’ are provided for attaching the pre-combustion chamber 7 to the separator 5 oxygen. Plate 118’ of the collection and tubular grille 116’, in turn, attached to play tubular lattice 116’ for the passage of compressed gas “D”, containing oxygen, from the site of the turbine. Pre-combustion chamber 7 provided with a shaped head 162 dome-shaped configuration attached to the outer flange 120’ plate 118’ of the collection, for the education space 163 for the branched return line. The nozzle 151 for fuel injection passes through the shaped cylinder 162 for the injection of fuel to react with part of the oxygen in the compressed gas “D” containing oxygen, thereby raising the temperature of the compressed gas “D” containing oxygen to form a heated gas “And” containing oxygen with adequate temperature for efficient ion transport of oxygen. Curved rounded annular wall 164 is provided in order to help to reverse the flow of compressed gas “D” oxygen-containing, within a shaped head 162. The gas stream, depleted in oxygen is returned to the turbine through a concentric inner channel 166. Concentric inner channel 166 is connected to the flange 167 which in turn is connected to the flange 32 of the channel 83.

In Fig.9 shows a flow chart of the process for grouping separators of oxygen in the gas turbine 6 for installation of the type shown in Fig.7. To the ode, it is shown in Fig.4, with the addition of the outer channel (for example, the outdoor channel 156 separator 5 oxygen) and pre-combustion chamber connected to the outside channel in the same manner as the connection of the preliminary combustion chamber 7 with an outer channel 156 separator 5 oxygen. Although shown only two oxygen separator, you must understand that the Association includes many separators oxygen connected with multiple combustion chambers 150, distributed around the periphery of the connecting channel between the compressor 146 and extender 148.

The air is extracted from the release of the compressor of the gas turbine as a stream 170 air. Thread 172 additional compressed feed air is provided by a separate air compressor 173 and mixed with stream 170 of the produced compressed air. Although not shown, this can be done in the pre-combustion chamber, for example in the pre-combustion chamber 7, by adding additional input pipe for the air inside the shaped head 162. As you can appreciate, one compressor can supply all the separators 5 oxygen. The remaining threads of the separators 5 oxygen consisting of air, before entering the combustion chamber (not shown).

Threads 174 of the obtained oxygen formed from a previous oxygen, can be cooled via indirect heat exchange with a stream 175 used to increase the steam pressure. After that, the threads 174 of the obtained oxygen can be cooled further in the capacitor 176 to condense water, which is then separated in separator 178. Threads 174 of the obtained oxygen can then be compressed to a pressure supply to the compressor 180 oxygen.

To achieve high extraction of oxygen in the separators 5 oxygen past the oxygen must be removed on the vacuum level. To avoid this and provide oxygen to the compressor 180 oxygen under a slightly elevated pressure, steam, supplied via stream 165 is used as the washing gas separators 5 oxygen.

It should be noted that the water to produce steam 175 consists of water, separated from the stream 174 is received oxygen, and water recharge, which is supplied by pump 182 in the separators 5 oxygen.

For a typical modern gas turbine which compresses the air from about 13.8 to 31,05 bar, the amount of steam for purging, thus obtained, is sufficient to achieve the levels extracted is, and for the oxygen compressor 182 oxygen at about 1,72 bar, at the same time maintaining adequate driving potentials to move oxygen in the separators 5 oxygen.

To support energy production, additional air from the stream 172 additional supplied compressed air which is fed in the separators 5 oxygen must be at least equal to the volume of the extracted oxygen. Ideally, one module of the separator must be connected to each combustion chamber of the gas turbine. If you want to get the maximum power from this setup can be used multistage compression with intermediate cooling, because the power required to compress the stream 172 additional supplied compressed air (if its volume is the last volume of oxygen) is the power that you want to take away from the installation. However, in most cases, the overall efficiency of the cycle with intermediate cooling will be less than without it.

In Fig.10 shows the separator 5’ oxygen, which can be combined in a manner shown in Fig.7, without pre-combustion chamber 7 running continuously.

The separator 5’ oxygen has an internal AC oxygen, posted by inside section 186 for burning inner channel 184, act as a pipe of a combustion chamber for burning fuel or, optionally, the mixture of fuel and steam. Such burning is supported past oxygen extracted from the hot gas. Combustion heats the air that passes through the inner channel 184 to give the opportunity of ceramic membranes for the selection of oxygen in their design operating temperatures. Pre-combustion chamber 7 so should be used only to run in case of a merger between a pre-combustion chamber 7 and the combustion chamber 150. Ceramic membranes for selection of oxygen inside section 188 for separation channel 184, work to separate the oxygen from the heated air, which forms a hot gas “And” containing oxygen.

Section 186 for burning inner channel 184 has a multitude of elongated tubes 190, which is placed coaxially inside the ceramic membranes 36 for selection of oxygen. Section 188 for separation channel 184 is also equipped with a number of elongated tubes 192, which are in connection with long pipes 190 and which is placed coaxially inside the ceramic membranes 36 for selection of oxygen. the ical membranes 36 for selection of oxygen, posted by inside section 188 for the Department.

Sections 186 and 188 for combustion and to separate the inner channel 184 and their internal components are mirror images of each other, although they can be applied ceramic membranes 36 for selection of oxygen in various lengths. Typical ceramic membranes 36 for selection of oxygen inside section 188 for the Department longer than the same membrane inside section 186 for burning.

In sections 186 and 188 for combustion and to separate the inner channel 184 elongated tubes 190 and 192 are connected with a pair of tube sheets 194, which in turn are connected to the Central mounting plate 195. Tube 194 have peripheral flanges connected to each other, such as by threaded fasteners (not shown) to connect the sections 186 and 188 for combustion and to separate from each other. Tube 194 and the Central mounting plate 195 is also provided with external radial rows of aligned holes 196 and 197, respectively, to allow passage of hot gas “And” containing oxygen, of section 186 for combustion in section 188 for the Department.

A pair of tube sheets 198 is provided for installation of ceramic membranes 36 for selecting color is 0 ceramic membranes 36 for selection of oxygen. A pair of caps 203 a cylindrical configuration attaches the plate 200 collector to the tube grids 194 for education filled spaces. Filled space provide an opportunity to introduce the fuel and, optionally, other threads in ceramic membranes 36 ionic conductivity for the selection of oxygen, which act as pipes of the combustion chamber, and to collect oxygen and combustion products, including moisture and carbon dioxide, ceramic membranes 36 for selection of oxygen, which act solely as separators. Appropriate means for heat transfer, for example, such as shown in U.S. patent 5820654, which is included here by reference as fully set forth herein are preferably used to prevent any overheating or quenching the reaction.

The inlet pipe 204 for fuel and outlet piping 206 pass through sections 186 and 188 for combustion and for the Department, respectively, and are connected with the filled in spaces formed by the lid 203. The fuel and, optionally, steam, introduced into the inlet pipe 204 for fuel, and the intervening oxygen and combustion products, including moisture and carbon dioxide and any steam produced from the output of the pipeline 206. Carbon dioxide mon, containing oxygen, is fed from the output of the compressor through the annular space 210 formed between the outer channel 212 and section 188 to separate the inner channel 184. Gas “D” containing oxygen, passes through the radial holes 214 and 216 formed in the plates 194 collector and the Central mounting plate 195, respectively, and then passes through the annular space 218 formed between the outer channel 212 and section 186 for burning inner channel 184. The thread is rotated 180through walls 221 and then enters into the inside of the section 186 for burning. As shown, the outer channel 212 is formed of two sections 222 and 224, which is attached to the outer flanges 226 of the plate 194 of the collection. Other parts of the flanges 226, in turn, are connected to the Central mounting plate 195.

Although the present invention is shown with reference to the oxygen separators, which use ceramic membranes for selection of oxygen, oriented in line with the flow of heated gas “And” containing oxygen, the present invention should not be construed as limited by such design. For example, in Fig.11 shows an alternative design is Antonovna at right angles to the flow within the channel 230. Ceramic membranes 36 for selection of oxygen is connected with the tube plate 232, which is in turn connected to the plate 234 of the collection. Vertical design 236 having the same configuration as the screen 90, connected to the channel 230. Round flanges 238 and 240 are attached to the channel 230 and the vertical structure 236, respectively, and to each other by fasteners (not shown).

Vertical design 236 operates to receive cooling air 16 to cool the intervening oxygen flowing inside ceramic membranes 36 for selection of oxygen, part ceramic membranes 36 for selection of oxygen surrounded by a vertical structure 236, and, therefore, such support structure, as tubular bars 232 and plate 234 of the collection. After that, the stream 16, is heated by heat exchange with the hot oxygen combines with the heated air “And” containing oxygen from the generator 1 hot gas of the gas turbine to separate the inside parts of the ceramic membranes 36 for selection of oxygen, protruding into the channel 230. In this regard, the channel 230 is connected directly to the generator 1 hot gas of the gas turbine by means of the flange 242 and the power turbine 3 at its opposite end through primer

In the calculated example for option generator 1 hot gas of the gas turbine is converted aircraft engine presents the comparison between the standard Case I only for energy production, Case II - for the joint production of oxygen through the joint separator 2 oxygen with a vacuum pump and comparative Case III with the separator 2’ oxygen by blowing steam to produce oxygen pressure above atmospheric. Steam is produced by heat from the exhaust gas power turbine. The cycle, shown in Fig.2 (with optional air), was used for more oxygen. Case IV for unmerged cooling units and a separate power plant included for comparison.

The main assumptions were as follows.

The compression ratio of the compressor hot gas generator of the gas turbine: 30

The compressor hot gas generator of the gas turbine: without intermediate cooling

The additional air compressor: 2-speed with intermediate water cooling

Vacuum pump O2: 3-speed with intermediate water cooling

the efficiency of the air compressor 80%

the turbine efficiency of 90%

the efficiency of the vacuum pump oxygen 70%

The temperature of the hot gas 1154

The temperature at the outlet of the power turbine 761

The table below shows that in the cases of United "MARK" saves significant power compared to a separate cryogenic installation. In the case of steam blowdown saves power compressor oxygen and the costs of additional investments in equipment to generate steam and heat exchangers. In this case, it is assumed that there is no competitive use of waste heat.

If we assume that the average oxygen flow in the separator "MARK" 8.49 m3(STD,)/hm2the area of the separator will be 84,236 m2. For pipes with a length of 3.66 m, with a diameter of 2.54 cm, split step to 3.49 cm, the beam diameter will be about to 2.06 m Leaving approximately 0.76 m to the isolation and size of the thread on the periphery, will receive as a result, the diameter of outer casing approximately 2.9 m

If you use a circular arrangement according to Fig.11 when the diameter of the inside area of the flow 1,22 m, outer diameter of the beam should be approximately at 2.36 meters This will result in the diameter of about 2,74 m

At that time, as the present invention is described with reference to a preferred embodiment, the special is s, without going beyond the nature and scope of the present invention.
