METHODS FOR INCREASING CARBON DIOXIDE CONTENT IN GAS TURBINE EXHAUST AND SYSTEMS FOR ACHIEVING THE SAME
First Claim
1. A method comprising:
- compressing air in a first compressor;
combusting the air along with a hydrocarbon fuel in a turbine;
generating an exhaust gas stream from the turbine;
separating the exhaust gas stream into a first portion and a second portion;
separating carbon dioxide from the first portion;
compressing the second portion in a second compressor; and
recirculating the compressed second portion to the turbine.

Abstract
Disclosed herein is a system comprising a first compressor; the compressor being operative to compress air; a turbine; the turbine being disposed downstream of the first compressor; the turbine being operative to combust a hydrocarbon fuel along with compressed air from the first compressor to produce an exhaust gas stream; and a second compressor; the second compressor being disposed downstream of the turbine; the second compressor being operative to compress the exhaust gas stream and to recycle the compressed exhaust gas stream to the turbine. Disclosed herein is a method comprising compressing air in a first compressor; combusting the air along with a hydrocarbon fuel in a turbine; generating an exhaust gas stream from the turbine; compressing the exhaust gas stream in a second compressor; recirculating the compressed exhaust gas stream to the turbine; separating carbon dioxide from the exhaust gas stream; and storing the carbon dioxide.
