Abstract

A combined main air/O2 enriched product compressor for use with an air separation unit that produces O2 enriched product is provided that includes a prime mover that drives a bull gear. The bull gear drives at least two pinion gears, and the pinion gears drive several compression stages where at least one compression stage compresses feed air for the air separation unit and at least one compressor stage compresses O2 enriched product from the air separation unit. The combined main air/O2 enriched product compressor satisfies all air separation unit feed air requirements and at least some compression for the oxygen product from the air separation unit. A method is also provided.
