The air distillation unit ( ) has a low-pressure column ( C) which operates clearly above atmospheric pressure. The waste nitrogen coming from this column serves to purge, under low pressure, the air purification adsorbers ( A, B) in order to desorb them of the contaminants (water and CO ), then is mixed with the impure nitrogen stream sent directly to the nitrogen compressor ( ) which feeds the combustion chamber ( ) of the gas turbine ( ). At the start of regeneration, each adsorber is decompressed down to atmospheric pressure, then brought back up to the low pressure by impure nitrogen.

Method of feeding, with impure nitrogen, the combustion chamber of a gas turbine combined with an air distillation unit, and corresponding electricity generation plant
