Method, device and use for selective degassing from washing liquid

摘要

The invention relates to a method and an apparatus and their use for degassing of methane from a carbon dioxide-containing predominantly consisting of water washing liquid, in particular in a pressurized water wash, wherein electromagnetic waves or electromagnetic alternating field to the washing liquid within a frequency range in which by the action the binding of methane in the scrubbing liquid is reducible and / or the methane in the scrubbing liquid is excitable to move (100). As a result, methane contained selectively in the scrubbing liquid is degassed, which solves environmental and emission problems at low cost.
