【 摘 要 】

References(25)Cited-By(1)The desorption of SO2 from sodium phosphate buffer solution was investigated using a laboratory-scale rotating packed bed (RPB). The effects of operating parameters such as the high-gravity factor (β) of the RPB, gas–liquid ratio (G/L), sodium phosphate concentration (CL), preheating temperature (t), and pH of SO2-rich solutions on the desorption efficiency (θ) of SO2 were investigated. The experimental results showed that all factors except CL have significant effects on θ, and θ decreases with increasing rich solution pH and CL, but increases with increasing β, G/L, and t. Under the optimal conditions of β=60–80, pH≤5, G/L≈800 m3/m3, CL<2 mol/L, and t≈90°C, θ can exceed 90%. The obtained results imply great potential for RPB use in SO2-loaded solution desorption.
