circulation of the particles in the absorber, their mutual abrasive action, removal of the treated layer and exposure of non-treated material
the sorbent is carried into the reactor in dry powder form which eliminates problems with preparation, storage and injection of the suspension transport routes
water and sorbent are added separately into the process which eliminates problems with cleaning the pipeline routes; all water is evaporated as a result of heat generated by the flue gases
Ca/S ratio = 1.25 – 1.9 in the broad range of input SO2
concentration recirculation of the desulphurisation product, utilisation of the residual hydrate in the product
desulphurisation efficiency over 90%, suitable for medium-sized to large sources
flue gas temperature is above the dew point which eliminates the need for the installation of special materials
a solid desulphurisation product which eliminates problems with waste water
