Zusammenfassung:Acidic gases such as carbon dioxide are removed from a gaseous mixture including the acidic component by contacting the gaseous mixture in a scrubbing system with an acid absorbing solution comprising a basic alkali metal compound and an activator, during which process at least a portion of the activator is converted to cyclic urea. At least a portion of the scrubbing solution is transferred to a thermal conversion zone (40) wherein at least a portion of the cyclic urea is converted back to the activator afterwhich the scrubbing solution is returned to the scrubbing system from the thermal conversion zone (40).
