Process for air fractionation by low-temperature rectification |
摘要 |
In a system for air fractionation by low-temperature rectification, refrigeration is produced in a cooling stage by compression and expansion of the feed air or of nitrogen from rectification. By using the work gained during expansion for compressing only a partial stream of the gas passed through the cooling stage, the system according to this invention operates with increased efficiency and lower operating costs.
