摘要： A method and apparatus for producing a krypton-xenon-rich stream in which a pipeline oxygen stream is removed from an oxygen pipeline at ambient temperature and then distilled in a cryogenic rectification plant to produce the krypton-xenon-rich stream from a column bottoms of a distillation column. The plant can generate its own refrigeration by way of a heat pump loop incorporating an expander or, alternatively, refrigeration can be added by means of a liquid oxygen reflux stream introduced into the top of such distillation column.
