Abstract (en)
[origin: WO2012001125A2] The invention relates to a method and device for regenerating loaded amine-containing detergent solutions from gas scrubbing processes of gases such as biogases, waste gases from chemical processes or associated petroleum gases in which CO2 and/or sulfur compounds are present in chemically bound form. The detergent solution is heated to 20 - 96ºC, brought in contact with a flush gas and stripped over 3 to 180 minutes and after separation of the flush gas component said detergent solution is fed as a condensate to a membrane or similar separating unit, where the non-condensed flush gas component is separated. The condensed flush gas is evaporated again and circulated back into the circuit. The desorption is very effective and nearly complete, and because of the low heating temperature, technical low-temperature sources can be used such as co-generation plant cooling water waste heat, solar heat, geothermal heat, industrial waste heat and/or process heat.
