The true issues of organizations are situated now in their capacity of facing industrial risks and unexpected events due to their activities. Hydrogen sulfide H2S, is a highly toxic gas and a very aromatic chemical. This chemical species is especially produced by some industrial activities such as paper industries and oil refineries. Themethods to eliminate themare burning treatment and stripping in a filling tower. The disadvantage of this treatment plant is the importance of corrosion of itsmetals byH2S. The goal of our study is to bring alternatives in order to set up a new treatment process able to drain acid waters of condensates from the source. The tests of desulfurization by concentrated sulfuric acid combined to airing have generally given good results with a treatment yield that can reach 99%.
