Sulphur dioxide gas scrubbing process
Patent
·
OSTI ID:6351340
Sulfur dioxide is removed from a gas stream by contacting the gas with an aqueous solution containing sulfite anion, magnesium cation, and one or more other cations whose sulfite salts are more soluble than magnesium sulfite. The contacting solution is regenerated with magnesium oxide or hydroxide and then recycled.
