Abstract
Pressurized byproduct gas from an air separation system is work expanded and the resulting work is used to compress supplemental feed air which is combined with a main feed air stream to supply a total air feed to the air separation system. Supplemental air can be provided only during off-design operation when the main feed air stream is insufficient to provide the total air feed to the system. Alternatively, supplemental air can be used continuously in combination with a reduced main feed air stream to provide total feed air to the system.
