Abstract:
1. A power system, comprising: a first compressor unit configured to compress an air stream and form a first pressurized stream; a syngas generator in fluid communication with a fuel stream and the first compressor unit and configured to generate a first syngas stream; a syngas expander unit configured to directly receive the first syngas stream from the syngas generator and to reduce a pressure of the first syngas stream to form a second syngas stream; a first steam generator configured to cool the second syngas stream to a cooled syngas stream; a water gas shift reactor configured to convert carbon monoxide in the cooled syngas stream to carbon dioxide and to form a converted syngas stream; a carbon dioxide removal unit configured to remove carbon dioxide from the converted syngas stream and to form a carbon dioxide stream and a hydrogen stream; and a gas turbine unit configured for receiving the hydrogen stream and for generating power.
