Embodiment 1

[0263] A base gas turbine engine was simulated for comparison with the integrated systems in Examples 2 to 5 presented below. A basic gas turbine not integrated with an ion transport membrane system can be removed by removing Figure 4 The combustion heater 217, the ion transport membrane system 221, the pipeline 401, the pipeline 403, the pipeline 409 and the pipeline 423 in the system are illustrated. In this basic gas turbine, the combustor 405 operates as the combustor previously described with reference to Figure 1, and runs on natural gas fuel.

[0264] Liner inlet cooling air based on 851°F (line 411, Figure 4 ) temperature and use the following engine properties:

[0265] · Compression ratio (compressor 203) = 20 / 1

[0266] · Air flow rate (compressor 203 discharge) = 344 lb / sec

[0267] ·Turbine Inlet Temperature (Turbine 257) = 2200°F

[0268] Overall air / fuel ratio = 50 / 1

[0269] · Compressor Efficiency (Compressor 203) = 85%

[0270] Turbo Efficiency (Turb...

Embodiment 2

[0274] Using the engine performance parameter simulation of embodiment 1 Figure 8 Shown is the integrated gas turbine and ion transport oxygen generation system. This baseline scenario illustrates a typical integrated gas turbine and ion transport oxygen generation system of the prior art and provides a point of reference for comparison with Examples 3-5 presented below. For this baseline example case, the amount of compressed air taken from the gas turbine compressor discharge and sent to the ion transport oxygen generation system was chosen to achieve an oxygen concentration of 14% by volume at the inlet of the power burner 805 . This oxygen concentration was chosen for the illustrative purposes of this example; other concentrations may be used in actual practice if desired.

[0275] refer to Figure 8 , at 851°F, 344 lb / sec of input air in line 201 is compressed in compressor 203 to 291 psia and split into two parts via lines 207 and 209. A first portion of compressed a...

Embodiment 3

[0278] Using the engine parameters of Example 1 and image 3 The burner configuration simulation figure 2 Shown is the integrated gas turbine and ion transport oxygen generation system. The system performance achievable for this embodiment is primarily a function of splitting the airflow required for combustion and liner cooling. For conventional gas turbines, the liner cooling air flow as part of the compressor discharge typically ranges from 10% to 40%, while the amount of air required for combustion depends on how depleted the combustion process is in the primary zone ( lean) how. For Dry Low NO x combustor, a lean primary zone equivalence ratio (eg, 0.5) is necessary. The equivalence ratio, Φ, is defined as the actual fuel / air ratio divided by the stoichiometric fuel / air ratio. If another NO x Methods of control (eg, water injection), equivalence ratios as high as 1.0 in the primary zone can be used. The required corresponding combustion air as part of the compress...

Abstract

Integrated gas turbine combustion engine and ion transport membrane system comprising a gas turbine combustion engine including a compressor with a compressed oxygen-containing gas outlet; a combustor comprising an outer shell, a combustion zone in flow communication with the compressed oxygen-containing gas outlet, and a dilution zone in flow communication with the combustion zone and having one or more dilution gas inlets; and a gas expander. The system includes an ion transport membrane oxygen recovery system with an ion transport membrane module that includes a feed zone, a permeate zone, a feed inlet to the feed zone in flow communication with the compressed oxygen-containing gas outlet of the compressor, a feed zone outlet, and a permeate withdrawal outlet from the permeate zone. The feed zone outlet of the membrane module is in flow communication with any of the one or more dilution gas inlets of the combustor dilution zone.

Description

[0001] Statement Regarding Federally Sponsored Research or Development [0002] This invention was made in part with support from the US Department of Energy under cooperative agreement DE-FC26-98FT40343. The government has certain rights in this invention. Background technique [0003] By using an oxygen-permeable mixed-metal oxide ceramic membrane, air can be separated at high temperature to produce high-purity oxygen. These membranes operate by selective permeation of oxygen ions and can be described as ion transport membranes. Mixed metal oxide materials for ion transport membranes can be mixed conductors that conduct oxygen ions and electrons, where the permeating oxygen ions recombine on the permeate side of the membrane to form oxygen. [0004] The feed gas to an ion transport membrane separation system is an oxygen-containing gas (eg, air) that is compressed and heated prior to the membrane system to a typical temperature range of 700°C to 1100°C. A portion of the ...
