Absorption of Sulphur Dioxide with Sodium Citrate Buffer Solution in a Rotating Packed Bed

Abstract

Abstract: Absorption of SO₂ from a SO₂/air mixture with sodium citrate buffer solution was investigated using a rotating packed bed(RPB) in laboratory scale.The effects of operating parameters, such as the rotation speed of RPB, liquid-gas ratio, inlet gas flow rate, inlet concentration of SO₂ in flue gas, sodium citrate buffer concentration and initial pH of absorption solution, on the SO₂ concentration in the absorption solution or removal efficiency of SO₂ were examined.Incremental rate of sulfate radical ions in the absorption solution was also examined.Experimental results indicate that the efficiency of this regenerative process will be improved by using RPB under appropriate operating conditions, and the generation of SO₄^2- will be restrained in the process in RPB.

Key words: SO₂ absorption, rotating packed bed, sodium citrate buffer solution
