Abstract
Official abstract text for this publication.
The invention is directed to a method for separating acid gases from a gas mixture in which the gas mixture is contacted with an absorption medium which comprises water and at least one amine and has a phase-separation temperature in the range from 0 to 130° C. In addition, the invention is directed to a device which can be used for carrying out this method.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for separating acid gases from a gas mixture, said method comprising: a) absorbing acid gases by contacting the gas mixture with an absorption medium comprising water and at least one amine to obtain a loaded absorption medium, wherein absorption takes place in an absorber and the absorption medium: i) shows phase separation into two liquid phases upon heating above a phase-separation temperature in the range of 0 to 130° C.; ii) comprises at le…
