Abstract: Es wird ein Verfahren zur Abtrennung von C 5 -C 8 -Kohlenwasserstoffen und Sauergasen aus einem Fluidstrom beschrieben, bei dem man
a) den Fluidstrom in einer Absorptionszone mit einem Absorptionsmittel in Kontakt bringt, das mindestens ein Amin enthält, wobei man einen entsäuerten Fluidstrom und ein mit Sauergasen beladenes Absorptionsmittel erhält,
b) das beladene Absorptionsmittel in einem ersten Wärmetauscher erwärmt und in eine Dekompressionszone auf einen Druck von 5 bis 10 bar entspannt, wobei man eine C 5 -C 8 -Kohlenwasserstoffe enthaltende Gasphase und ein Kohlenwasserstoff-abgereichertes beladenes Absorptionsmittel erhält,
c) das Kohlenwasserstoff-abgereicherte beladene Absorptionsmittel in einem optionalen zweiten Wärmetauscher erwärmt und in einen Stripper leitet, in dem die Sauergase bei einem Druck von 1 bis 2,5 bar durch Zufuhr von Wärme zumindest teilweise freigesetzt werden, wobei man ein regeneriertes Absorptionsmittel und einen Sauergas enthaltenden Strom erhält, und
d) das regenerierte Absorptionsmittel in die Absorptionszone zurückführt,
wobei man als Heizmedium im zweiten Wärmetauscher das regenerierte Absorptionsmittel verwendet und als Heizmedium im ersten Wärmetauscher das regenerierte Absorptionsmittel nach dem Passieren des zweiten Wärmetauschers verwendet, und die im ersten Wärmetauscher und im zweiten Wärmetauscher übertragenen relativen Wärmemengen so gewichtet, dass die C 5 -C 8 -Kohlenwasserstoffe enthaltende Gasphase 50 bis 97 Vol.-% Sauergase enthält.
