Sulfur dioxide (SO 2 ) is basically resulted from emission of fossil fuel. The ammonia washing is of methods used to remove SO 2 from fuel gas. Several wastewaters contain high ammonia concentrations causing the various problems at wastewater treatment or receiving environment. The synthetic wastewater containing NH 3 was sprayed down as flue gas moved up in the scrubber so that it could be a reaction between SO 2 and NH 3 . The effect of NH 3 concentration and pH on SO 2 removal was determined. SO 2 was decreased from about 1,000 to 0, 36, 49 and 66 ppm at NH 3 concentrations of 328, 88, 32 and 9 mg l −1 , respectively. While SO 2 of 1,000 ppm was completely treated at 328 mg NH 3 l −1 , pH was around 7.16 at the end of process. Consequently, it was recognized that this process could be used for both the SO 2 removal and the wastewater neutralization.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
