Abstract
In an integrated power generation system, part of the air from a gas turbine compressor is separated in a single nitrogen wash column to remove oxygen and the 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. Liquid from the bottom of the wash column may be fed back to the air separation unit. In order to boost production of an air separation plant, an additional plant is linked with the original plant. For example, air may be separated in a single nitrogen wash column to remove oxygen and gaseous nitrogen is produced at the top of the column. The wash column is fed with liquid nitrogen from the high pressure column of the air separation unit. Liquid from the bottom of the wash column may be fed back to the air separation unit.
