Sulfur dioxide (SO 2 ) and nitrogen oxides (NO x ) in flue gas are a hazardous atmospheric pollutant associated with coal combustion and non-ferrous metal production. Here we report that laboratory pilot unit for scrubbing of industrial flue gas containing 80 ± 2 ppm SO 2  followed by melt regeneration with either CO or natural gas, verified that only 1.5–2.0 ppm SO 2  remained in the flue gas. The tests with the semi-industrial scale unit (271.26 kg of the eutectic carbonate melt and flue gas containing 0.15% SO 2 , 13 ppm NO, 52 ppm NO 2 ) were received. In all tests, sulfur extraction from flue gas to the carbonate melt was &gt;90–95% and nitrogen oxides extraction from flue gas to the carbonate melt was 60%. Sulfur and nitrogen oxides extraction from carbonate–sulfate–nitrite melt during regeneration stage was &gt;99%. Carbonate melt-based SO 2  scrubbing therefore represents a practical and economical method for limiting sulfur and NO x  emission to the atmosphere from both coal-firing power stations and non-ferrous metallurgical processing plants.
