INTEGRATED APPARATUS FOR GENERATING POWER AND/OR OXYGEN ENRICHED FLUID, PROCESS FOR THE OPERATION THEREOF AND AIR SEPARATION PROCESS ANDAPPARATUS

摘要

In an integrated power generation system, part of the air from a gas turbi ne compressor is separated in a single nitrogen wash column to remove oxygen an d gaseous nitrogen produced at the top of the column is sent back to a point upstream of the expander of the gas turbine. The wash column may be fed with liquid nitrogen from an independent air separation unit, in which air is separated by cryogenic distillation. Liquid from the bottom of the wash column may be fed back to the air separation unit
