Low emission power generation and hydrocarbon recovery systems and methods

An integrated system, comprising:

• an air separation unit configured to produce an oxygen stream and a nitrogen stream;
• a gaseous control fuel stream;
• a combustion unit configured to combust at least the gaseous control fuel stream and the oxygen stream to produce a gaseous combustion stream having carbon dioxide and water;
• a power generation system configured to receive the gaseous combustion stream having carbon dioxide and water and produce at least a compressed gaseous carbon dioxide stream comprising from about 60 volume percent (vol %) carbon dioxide to about 95 vol % carbon dioxide;
• a first injector unit configured to inject at least a portion of the compressed gaseous carbon dioxide stream into an enhanced oil recovery reservoir;
• a second injector unit configured to inject at least a portion of the nitrogen stream into a pressure maintenance reservoir;
• a first hydrocarbon recovery reservoir configured to produce a first hydrocarbon mixture;
• and
• a first hydrocarbon separation unit configured to separate at least liquid hydrocarbons from the first hydrocarbon mixture and produce a first hydrocarbon stream and a secondary gas stream comprising carbon dioxide and hydrocarbons, wherein the combustion unit is further configured to utilize at least a portion of the secondary gas stream with the gaseous control fuel stream and the oxygen stream to produce the gaseous combustion stream having carbon dioxide and water.
