Sulphur dioxide removal using activated sorbents

Results are presented of experimental investigation of the dry flue gas des ulphurisation (FGD) process at low temperatures using activated sorbents. S olid wastes (ashes) from the dry (with humidification) FGD plant are used a s a sorbent. The influence of basic operating parameters on the efficiency Of SO2 removal is determined. More than twofold sulphur dioxide removal eff iciency is obtained using activated sorbents in comparison with the efficie ncy obtained in the process with dry sorbents. The possibility of reduction of sorbent consumption in the dry method of FGD with humidification is fou nd.
