Abstract: The invention concerns a method for producing synthetic gas on an industrial site comprising at least one gas turbine wherein the oxygen-containing gas produced by the gas turbine is upgraded in a combustion implemented on the industrial site or in a heat recovery unit of the industrial site. Preferably, the oxygen-containing gas is used as oxidant of the combustion thereby enabling the reaction for forming the syngas. The invention also concerns a method for controlling the introduction of the oxygen-containing required for combustion to enable the syngas to be formed into a syngas reactor and an associated device.

Abstract: The invention concerns a method for producing syngas by means of a syngas producing unit comprising: at least one syngas producing reactor producing from hydrocarbons: a crude syngas comprising hydrogen, CO and CO2 and an exhaust gas comprising CO2; a device for eliminating CO2 from said crude syngas producing a gas comprising essentially CO2, said gas comprising essentially CO2 being recycled into the syngas producing reactor on an industrial site further comprising: at least one heat and/or electricity producing unit producing an exhaust gas comprising CO2; a device for eliminating CO2 from the combustion exhaust gases of the site, wherein: at least one of the exhaust gases comprising CO2 produced by the syngas producing reactor or by the heat and/or electricity producing unit is treated in the device eliminating CO2 from the combustion exhaust gases of the site; and the CO2 produced by treating the exhaust gases of the syngas producing unit and/or the heat and/or electricity producing unit by the device el
