Wet scrubbing	See Section 1.20.3
SNO_X combined technique	Combined technique to remove SO_X, NO_X and dust where a first dust removal stage (ESP) takes place followed by some specific catalytic processes. The sulphur compounds are recovered as commercial-grade concentrated sulphuric acid, while NO_X is reduced to N₂. Overall SO_X removal is in the range: 94-96,6 %. Overall NO_X removal is in the range: 87-90 %
