A method which include an air intake into an air separation unit; extracting from the separation unit at least a gas stream, essentially consisting of an air gas, in particular oxygen or nitrogen, and directing one or more of these gas streams towards the combustion chamber of a gas turbine; control
A method which include an air intake into an air separation unit; extracting from the separation unit at least a gas stream, essentially consisting of an air gas, in particular oxygen or nitrogen, and directing one or more of these gas streams towards the combustion chamber of a gas turbine; controlling at least one parameter related to the or each gas stream, by acting on a compressor in each gas stream arranged downstream of the air separating unit; assigning to one or more parameter a variable setpoint value, based on a value representing the load of the gas turbine.

What is claimed is: 1. A method for producing energy using a gas turbine associated with an air separation unit, comprising: a) admitting air into said air separation unit, b) extracting at least one of an oxygen stream or a nitrogen stream from said air separation unit, c) compressing said oxygen
What is claimed is: 1. A method for producing energy using a gas turbine associated with an air separation unit, comprising: a) admitting air into said air separation unit, b) extracting at least one of an oxygen stream or a nitrogen stream from said air separation unit, c) compressing said oxygen stream with a first compressor, said first compressor being located downstream of said air separation unit, d) compressing said nitrogen stream with a second compressor, said second compressor being located downstream of said air separation unit, e) directing said oxygen stream toward a gasifier, f) directing said nitrogen stream toward a combustion chamber of said gas turbine, g) controlling at least one parameter associated with at least one of said oxygen stream or said nitrogen stream with said first compressor or said second compressor, wherein said at least one parameter is pressure, and h) assigning a first variable setpoint value that varies as a function of a value representative of the load on the gas turbine to said at least one parameter, wherein said value representative of the load on the turbine is a specific pressure value on the intake side of said gas turbine, wherein the pressure inside said gasifier is also controlled by assigning to it a second variable setpoint that varies as a function of said pressure value. 2. The method as claimed in claim 1, wherein said second variable setpoint value is equal to said pressure increased by a third safety value. 3. The method as claimed in claim 2, wherein said third safety value is between 0.5 and 10 bar. 4. The method as claimed in claim 3, wherein said third safety value is between 1 and 5 bar. 5. An apparatus for producing energy using a gas turbine associated with an air separation unit, comprising: a) means for extracting at least one of an oxygen stream or a nitrogen stream from said air separation unit, b) a first compression means for compressing said oxygen stream, wherein said first compression means is located downstream of said air separation unit, c) a second compression means for compressing said nitrogen stream, wherein said second compression means is located downstream of said air separation unit, d) means for conveying said nitrogen stream toward a combustion chamber of said gas turbine, e) means for conveying said oxygen stream toward a gasifier, f) control means for controlling at least one parameter associated with at least one of said oxygen or nitrogen streams, wherein said control means acts directly on said first compression means or said second compression means, and wherein said control means has a variable setpoint value that varies as a function of a value representative of the load on said turbine, wherein said control means controls the pressure of said at least one of said oxygen or nitrogen streams, and g) measurement means for measuring the pressure on the inlet side of the gas turbine, wherein said measurement means controls the pressure of said gasifier.
