• Abstract:Using a multi-parameter sonochemical reactor, the process of removing sulfur dioxide from citrate solution in flue gas desulfurization was studied. The influence of ultrasonic frequency, ultrasonic power, reaction temperature, stirring speed, inert gases, the initial concentration of sulfur dioxide and concentration of citrate on the desorption efficiency of sulfur dioxide, the stability of citrate solution and the concentration of vitriolic radical was examined systematically. By comparing the desorption of sulfur dioxide with and without ultrasonification, it was concluded that (1) lower ultrasonic frequency results in a better degassing efficiency; (2) the use of ultrasonification in desorbing sulfur dioxide from citrate solution can improve the desorbing efficiency in some conditions, without changing the essence of reacting process; (3) sparging inert gas into the liquid can lower the viscosity of solution and the cavitating value, and raise the desorption efficiency of sulfur dioxide. These results demonstrate a technical way for deep desorption of sulfur dioxide and provide the fundamental data for future industrial disposal of sulfur dioxide.
