Power turbine system

A power turbine system, comprising:

• a multi-stage ion transport membrane reactor, the multi-stage ion transport membrane reactor having an elongate fuel evaporation core, a first air delivery passage disposed above the fuel evaporation core, a button cell ion transport membrane disposed between the fuel evaporation core and the first air delivery passage, and a plurality of ion transport membranes spaced from the elongate fuel evaporation core and the first air delivery passage, the membranes defining corresponding working chambers therebetween;
• a first power turbine communicating with the reactor;
• a second power turbine communicating with the reactor;
• and
• an air compressor communicating with the second power turbine and the reactor.

A method for liquid fuel combustion, comprising:

• providing a multi-stage ion transport membrane reactor, the multi-stage ion transport membrane reactor having an elongate fuel evaporation core, a first air delivery passage disposed above the fuel evaporation core, a button cell ion transport membrane disposed between the fuel evaporation core and the first air delivery passage, and a plurality of ion transport membranes spaced from the elongate fuel evaporation core and the first air delivery passage, the membranes defining corresponding working chambers therebetween, a first power turbine communicating with the reactor, a second power turbine communicating with the reactor, and an air compressor communicating with the second power turbine and the reactor;
• combusting a heavy liquid fuel in the reactor to produce a first exhaust product, the first exhaust product including carbon dioxide (CO2) and water (H2O);
• producing and combusting a synthetic gas in the reactor to produce a second exhaust product, the second exhaust product including carbon dioxide (CO2) and water (H2O);
• driving the first power turbine with the first exhaust product;
• driving the second power turbine with the second exhaust product;
• driving the air compressor using the second power turbine to compress atmospheric air;
• delivering the compressed air to the reactor from the air compressor;
• and
• separating oxygen from the compressed air in the reactor to combust the heavy liquid fuel in the reactor to produce the first exhaust product and to combust the synthetic gas in the reactor to produce the second exhaust product.
