Abstract

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.
