More Information
Summary:A gas desulfurization process is provided in which a gaseous mixture (10), comprising sulfur oxides is contacted in an absorption zone (12), at absorption conditions, with an aqueous composition (14) comprising ammonium carbonate, or ammonium bicarbonate or mixtures thereof, in an amount such that the product of the partial pressures of the sulfur oxides and ammonia over said aqueous composition is below a specified limit, to produce a gaseous product (18) having a decreased content of sulfur oxides and a decreased appearance of blue haze. A combination nitrogen oxides removal (deNOx) and desulfurization (deSOx) process is also provided.
