ABSTRACT:
A method, applicable to hydrogen sulfide removal systems which employ a regenerable aqueous washing solution capable of absorbing hydrogen sulfide and converting that hydrogen sulfide to elemental sulfur, is provided for reconditioning such systems after they have become contaminated with sulfur-feeding bacteria and/or for maintaining such systems substantially free of such bacteria. In the method of the invention, the aqueous washing solution is contacted with an aliphatic dialdehyde.
