Electrolytic process for desulphurization and seed regeneration in coal fired magnetohydrodynamic (MHD) power generation systems
An electrolytic process for desulphurization and seed reprocessing and recovery in open cycle coal fired MHD electrical power generation systems is disclosed. Alkali metal sulfate is removed from the gaseous effluent of the generator and electrolyzed in solution in an electrolytic cell to alkali metal hydroxide and sulphuric acid. The alkali metal hydroxide may be recycled directly into the system combustor or may undergo further conversion to alkali metal carbonate or bicarbonate or both by carbonation reaction with the carbon dioxide contained in the substantially desulfurized MHD generator effluent gas. An alternative electrolytic cell conversion of alkali metal bicarbonate to alkali metal carbonate is also disclosed.
