초록 ▼

The present invention provides a process of preparing of a gas composition suitable for the injection in an oil-containing field to increase the degree of recovery and simultaneously reduce the discharge of CO2to the atmosphere. However, injection of a gas composition containing large amounts of oxygen will result in a degraded submarine formation which is not desirable. The present invention relates to a process for the production of a gas composition comprising N2,CO2,minor parts of NOx,VOC (volatile organic compounds) and about 0-2.0 mole % O2from an oxygen containing exhaust gas, wherein a stream of an exhaust gas from the combustion of air and natural gas in a gas turbine containing 18% by weight O2or less, is combusted with natural gas, whereupon the desired gas composition is discharged as a flue gas. Further, a process of recovering oil from submarine formations is also described, where said gas composition is compressed and injected into a submarine formation. The use of previous said gas composition for injection in an oil-containing field for the recovery of oil is also disclosed by the present invention.

1. A process of recovering oil from a submarine formation, comprising the steps of: preparing a gas composition comprising N2,CO2,minor parts of NOxand VOC (volatile organic compounds), and about 0-2.0 mole % O2from an oxygen containing exhaust gas by combusting a stream of exhaust gas from the combustion of air and natural gas in a gas turbine containing 18% by weight O2or less with natural gas to form a desired gas composition and discharging the desired gas composition as a flue gas; and compressing and injecting said gas composition into said submarine formation. 2. The process of claim 1, further comprising the step of recovering oil from said submarine formation. 3. The process of claim 1, wherein the gas composition contains about 0 to 1.0 mole % O2. 4. The process of claim 3, wherein the gas composition contains about 0.1 to 0.5 mole % O2.
