Claims (2)
1. Verfahren zur Tieftemperatur-Rektifikation eines Gasgemisches, bei dem das zu zerlegende
Gasgemisch in zwei Teilströme verschiedenen spezifischen Flüssigkeitsgehaltes aufgeteilt wird,
von denen der zweite Teilstrom mit dem höheren Flüssigkeitsgehalt einige Böden oberhalb der
Einspeisestelle des ersten Teilstromes mit dem niedrigeren Flüssigkeitsgehalt in eine Rektifizierkolonne
entspannt wird, während der ebenfalls entspannte erste Teilstrom nach Anwärmung in
die Rektifizierkolonne geleitet wird, dadurch gekennzeichnet, daß der erste Teilstrom
nach seiner Entspannung Kälte an den Gesamt- ([ strom des zu zerlegenden Gasgemisches abgibt
und der so abgekühlte Gesamtstrom aufgeteilt wird in den ersten und in den zweiten Teilstrom.
2. Verfahren nach Anspruch 1, dadurch gekennzeichnet,
daß der zweite Teilstrom vor dem Entspannen in zwei weitere Teilströme aufgeteilt
wird, von denen der eine nach Entspannung Kälte an den zweiten Teilstrom abgibt und in die
Rektifizierkolonne geht, während der andere entspannt und einige Böden weiter oben in die Kolonne
geführt wird.
