| 摘要 |
The present invention provides a method of producing an oxygen-enriched air stream which includes compressing an air stream, dividing the compressed air stream into a first portion and a second portion, separating the second portion of the air stream to provide an oxygen gas product, introducing the oxygen gas product into the first portion of the compressed air stream to form an oxygen-enriched air stream, and then introducing the oxygen-enriched air stream to the process equipment, which may be by way of example a blast furnace.
