摘要: The invention relates to a method and an apparatus for cryogenic fractionation of gaseous feed comprising contact purifying-refrigerating column into the bottom which is injected partially condensed feed, said producing in its head portion residual gas liquid fractionating distillate at least thus recover this heavy compounds contained vaporized fraction feed.
