Abstract
The gas turbine system comprises a gas turbine engine, a first fuel line adapted to feed fuel to the gas turbine engine, a heat recovery steam generator adapted to receive flue gas exhausted from the gas turbine engine, and a second fuel line adapted to feed fuel to a post-burner of the heat recovery steam generator. A carbon dioxide capture unit is fluidly coupled to a stack of the heat recovery steam generator. A recycling line recycles flue gas from the stack of the heat recovery steam generator to the post-burner in the heat recovery steam generator. A carbon dioxide return line recycles a gaseous stream containing carbon dioxide from the carbon dioxide capture unit towards the gas turbine engine or the post-burner. Disclosed herein is also a power generation method with improved carbon dioxide capture.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
