Claim 23:
24. An offshore facility comprising:
an offshore production unit configured for producing a produced gas from a gas reservoir;
a gas turbine configured to receive the produced gas for producing power and a flue gas;
a first gas separator configured to receive the flue gas for at least partially removing nitrogen from the flue gas and for producing a carbon dioxide-enriched flue gas and a nitrogen-enriched flue gas;
a reformer configured to receive a portion of the produced gas from upstream of the gas turbine for producing a stream comprising carbon dioxide and hydrogen;
a second gas separator configured to receive the stream for at least partially removing carbon dioxide from the stream and for producing a carbon dioxide stream and a hydrogen stream;
an ammonia reactor configured to receive the hydrogen stream and the nitrogen-enriched flue gas for producing ammonia;
a gas compressor configured to receive the carbon dioxide-enriched flue gas and the carbon dioxide stream for producing a compressed gas; and
an injection unit configured for injecting the compressed gas from the gas compressor into the gas reservoir.
