    2001-5-1 · The oxygen is compressed to delivery pressure, while a portion of the nitrogen is used to regenerate the air pretreatment system. The major process advantage of the TSA-based system is that air has only to be compressed to a pressure that overcomes pressure drop through the air pretreatment and heat exchanger, thus reducing the amount of air compression power compared to a cryogenic plant.
