Which method is used for the dry removal of sulphur oxides from flue gases?

Which method is used for the dry removal of sulphur oxides from flue gases? Correct Answer Adsorption

The method is adsorption. Cyclones remove particulate matter. Tray towers, which are a method of absorption, are not used for dry desulphurization of flue gases. Incineration is adopted only when recovery produces no valuable products.

In a laboratory test run, the rate of drying was found to be 0.5 × 10-3 kg/m2.s, when the moisture content reduced from 0.4 to 0.1 on dry basis. The critical moisture content of the material is 0.08 on a dry basis. A tray dryer is used to dry 100 kg (dry basis) of the same material under identical conditions. The surface area of the material is 0.04 m2/kg of dry solid. The time required (in seconds) to reduce the moisture content of the solids from 0.3 to 0.2 (dry basis) is
