The semidry desulphurisation process is particularly suitable for systems up to 1 million Nm 3 /h flue gas. To purify the gases from SOx, but also from other acid components like HCl and HF, an aqueous absorbent ( lime slurry) is injected into the spray absorber. The acidic harmful gases react with the absorbent to form salts, while at the ...

Flue gas desulphurisation (FGD) describes a process that removes sulphur dioxide (SO2) from a flue gas ( exhaust gas) stream. Sulphur dioxide is released to the atmosphere when fossil fuels are burnt and it is a leading contributor to acid rain. The FGD process has become critical to many industrial plants due to increasingly stringent ...
