Fuel gas produced in a coal distillation or gasification plant 1 is fed to a power plant 5 and chlorine, fluorine, sulphur and compounds thereof in the fuel gas are separated from the fuel gas, and also from flue or exhaust gas emanating from the power plant, in two stages. In a first stage, chlorine and fluorine and their compounds are separated, preferably in the dry using alkali metal or alkaline earth metal oxides, hydroxides or carbonates, in a separator 3. In a second stage sulphur and its compounds, together with further chlorine, fluorine and their compounds, if any, produced in the power plant, are removed from the flue or exhaust gas from the power plant in a desulphurizing plant 6. This two stage process is thermally more efficient and less costly than a process in which the chlorine, fluorine sulphur and their compounds are all removed at once from the fuel gas.

A process where combustible gas from a coal degasification plant or gasification plant is used to power a turbine power plant, said combustible gas containing coke dust, chlorine, fluorine, sulfur, or compounds thereof, said process comprising separating the chlorine, fluorine, and compounds thereof
A process where combustible gas from a coal degasification plant or gasification plant is used to power a turbine power plant, said combustible gas containing coke dust, chlorine, fluorine, sulfur, or compounds thereof, said process comprising separating the chlorine, fluorine, and compounds thereof from the combustible gas prior to its use in the power plant in a dry separation process, said dry separation process employing an absorption agent selected from the group consisting of alkali metal or alkaline earth metal oxides, hydroxides, and mixtures thereof and alkali metal and alkaline earth metal carbonates and removing the sulfur and compounds thereof and remaining chlorine, fluorine and compounds thereof from the flue gas after it issues from the power plant
