Abstract (en)
[origin: WO2014170047A1] The invention relates to an absorbent which comprises a dissolved amino acid salt and a dissolved metal. The absorbent is brought into contact with the acidic gas in an absorber. In the absorber, the H2S converts from the gas phase to the liquid phase. In addition, carbon dioxide (CO2) is likewise absorbed from the gas as a function of the contact time. The washing solution is passed from the absorber to a regeneration tank. In the regeneration tank, the solution is gassed with air, oxygen (O2)-enriched air or with pure O2. By introducing O2 into the solution, the H2S already present in the solution is reacted over the dissolved metal catalyst. After the regeneration, possible solids are separated off and the regenerated washing solution is returned to the absorber.
