For preventing the fouling and/or plugging of apparatus with metallic sulfides in the processing and purification of synthesis gases contaminated with metal carbonyls, wherein the synthesis gases are scrubbed with a physical solvent, which solvent is regenerated and reused, an organic phosphite, e.g., trimethyl phosphite, and/or an organic phosphine, e.g., triethyl phosphine or triphenyl phosphine, is added as a complexing agent to the scrubbing media, preferably in between the scrubbing and absorption regenerating steps.
