Flue Gas Desulphuriser Explained

What is flue gas desulphurisation? Flue gas desulphurisation (FGD) describes a process that removes sulphur dioxide (SO 2) from a flue gas (exhaust gas) stream lphur 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
