SO2 absorption from industrial emissions in a fluidized bed of metal oxides

Among the air pollutants in the world, sulfur dioxide has been given special emphasis for posing danger to the environment. SO2 emissions in the air have harmful effects on human health and the environment. Respiratory problems, respiratory diseases and exacerbation of heart diseases are among dangerous symptoms for human health, especially when high concentrations of SO2 are emitted. Therefore, in the present study, a wide variety of dry and wet processes were investigated to identify an appropriate process to reduce the amount of sulfur dioxide. Ultimately, the use of a fluidized bed containing metal oxides which is a dry process was selected with regard to the factors such as simplicity of the process, having a minimum of waste water and gas, ability to reduce pollution levels to acceptable environmental standards. In order to examine the performance of this type of fluid beds, a laboratory scale unit was developed to investigate effects of various operational parameters including temperature, inlet gas rate and concentration, etc. on the amount sulfur dioxide emission by copper oxide.
