Abstract: A process for the generation of insert gas for backsurging and artificial lift for oil wells includes a step of admitting atmospheric air into a diesel engine through a turbocompressor. The flue gas from the engine is discharged to a first cooler for cooling the flue gas and then to a first cyclone for separating water and solid particles. The flue gas from the first cyclone is supplied to a first stage of a first compressor and from the first stage into a second cooler for further cooling the flue gas. The flue gas is discharged from the second cooler into a second stage of the first compressor and thereafter discharged into a third cooler. The flue gas is then supplied from the third cooler to a second cyclone downstream for further separating water and solid particles. The flue gas is discharged from the second cyclone to the first stage of a second compressor and then supplied to a fourth cooler.
