Apparatus and method for inducing and detecting fluorescence

A process is disclosed for removing total reduced sulfur compounds (TRS), especially H.sub.2 S and mercaptans, from industrial gases wherein substantially dry activated manganese dioxide absorbent particles are fluidized with the industrial gas at an elevated temperature sufficient to effect oxidation of the total reduced sulfur compounds and the absorption of the oxidized compounds on the absorbent particles. In preferred practice, the dried powder containing areas of the oxidized sulfur compounds is recovered as a particle layer in a bag filter unit through which the industrial gas is caused to flow.

A process and apparatus for removing total reduced sulfur compounds (TRS), especially H.sub.2 S and mercaptans from industrial gases is disclosed wherein an aqueous suspension of an active manganese dioxide is contacted with the industrial gas by atomizing the aqueous suspension in a spray dryer and contacting the atomized droplets with the industrial gas at a temperature sufficient to substantially completely evaporate the water in the atomized droplets. In preferred practice, the dried powder produced by the spray dry process is recovered as a particle layer in a bag filter unit through which the industrial gas is caused to flow.
