Cryogenic air separation with combined prepurifier and regenerators |
摘要 |
A method is provided for separation of air by cryogenic rectification comprising compressing feed air, passing the compressed feed air through a prepurifier wherein the air is substantially cleaned of impurities, thereafter cooling the cleaned air in a cooled regenerator and then introducing it into a cryogenic air separation facility wherein it is separated into nitrogen-rich and oxygen-rich components.
