The reaction mechanisms of the biological desulphurization process via chemolithotrophic bacteria activity for H 2 S removal and their kinetic models, when using oxygen (i.e., aerobic species) as electron acceptors, leads to the production of different sulphide oxidation products (S or SO 4 2−) depending on the oxygen mole ratio …
Flue Gas Desulphurization in Circulating Fluidized Beds
Sulphur dioxide (SO2) is mostly emitted from coal-fueled power plants, from waste incineration, from sulphuric acid manufacturing, from clay brick plants and from treating nonferrous metals. The emission of SO2 needs to be abated. Both wet scrubbing (absorption) and dry or semi-dry (reaction) systems are used. In the dry process, both …
