Abstract

U.S. Pat. No. 6,202,422 (Brugerolle) shows an air separation unit integrated with a gas turbine. It also describes a "nitrogen wash" column. Figure 1 shows such a column: Liquid nitrogen (LIN) is pumped to the top of the column and air from the gas turbine compressor is introduced to the bottom of the column. Gaseous nitrogen product (GAN) is recovered from the top of the column, warmed up against feed air stream, and subsequently used in the gas turbine. The bottom of the column produces O2-rich liquid (ORL).
