The present invention provides a number of inhibiting agents that are useful to reduce aldol condensation in diethanolamine scrubbers. Suitable inhibiting agents include: hydrogen peroxide; hydroperoxides; nitroalkanes; salts of hypochlorous acid; alkyl substituted aldehyde oximes; trialkyl phosphites; isothiuronium salts; 2-mercaptoethanol (C.sub.2 H.sub.6 OS); and, benzoic hydrazide. A preferred inhibiting agent for diethanolamine scrubbers is an excess of hydrogen peroxide.
