Patent attributes
In one embodiment, a power system comprises: a first compressor unit, a syngas generator in fluid communication with a fuel stream and the first compressor unit, a syngas expander unit configured to directly receive the first syngas stream from the syngas generator, a first steam generator, a water gas shift reactor, and a carbon dioxide removal unit. The first compressor unit is configured to compress an air stream and form a first pressurized stream, while the syngas generator is configured to generate a first syngas stream. The syngas expander is configured to reduce the pressure of the first syngas stream. The first steam generator is configured to cool the second syngas stream. The carbon dioxide removal unit configured to remove carbon dioxide from the converted syngas stream.
