A Process of Washing and Ozonation to Deodorize an Atmosphere Contaminated by Sulfides

Abstract

A treatment process of gas polluted by hydrogen sulfide or alkyl sulfide is described in this paper. It includes pollutant absorption by an aqueous solution and a continuous regeneration by an ozone oxidation of absorbed compounds. The effects of the main parameters of the process are discussed (pH, concentrations, flow rate,… ). Results are linked to the theory of mass transfer with chemical reaction.
