SYSTEM AND METHOD FOR PRODUCING CARBON DIOXIDE FOR USE IN HYDROCARBON RECOVERY

摘要

A method for producing carbon dioxide for use in hydrocarbon recovery has the steps of producing an exhaust stream from a combustion turbine, passing the exhaust stream through a heat recovery steam generator so as to produce a carbon dioxide-laden stream and a steam, absorbing the carbon dioxide from the carbon-dioxide laden stream into a solution, pumping the solution to a stripper so as to produce carbon dioxide gas, compressing the carbon dioxide gas from the stripper, and injecting the compressed carbon dioxide gas into a hydrocarbon-bearing formation. The combustion turbine and the heat recovery steam generator are portable.

1. A method for producing carbon dioxide for use in hydrocarbon recovery, the method comprising:
transporting a carbon-dioxide producing system to a location adjacent a hydrocarbon-bearing formation, said carbon-dioxide producing system including a combustion turbine, a heat recover steam generator, a stripper and an absorption chiller; producing an exhaust stream from said combustion turbine; passing the exhaust stream through said heat recovery steam generator so as to produce a carbon-dioxide laden stream and a steam; absorbing the carbon dioxide from the carbon-dioxide laden stream into a solution; pumping the solution to said stripper so as to produce carbon dioxide gas; compressing the carbon dioxide gas from said stripper; injecting the compressed carbon dioxide gas into the hydrocarbon-bearing formation; passing the steam from said heat recovery steam generator to said absorption chiller; passing air through said absorption chiller so as to cool the air therein; and delivering the cooled air from said absorption chiller as inlet air to said combustion turbine.
