【 摘 要 】

Sulfur dioxide (SO₂) emissions from chemical process plants are increasing at an alarming rate. It is necessary to implement the best methodology to reduce the SO₂ emissions. This paper presents physical modeling, computational fluid dynamics (CFD) analysis, and experimental analysis of a packed column used for flue gas desulfurization (FGD) process to reduce SO₂ emission at a greater extent. The packed column parameters such as liquid/gas (L/G) ratio, diameter, packed height and total height were determined using physical modeling with two–film gas–liquid absorption theory. Simulation model of the packed column is developed by GAMBIT 2.2.30 and analysis is carried out by FLUENT 6.2.16. In CFD analysis, hydrogen peroxide (H₂O₂) (with different concentrations) was used as an absorbent. CFD simulation result ensures that when H₂O₂ is used as a reactant, better removal efficiency is obtained. Based on the physical modeling and CFD analysis, a lab scale packed column was developed. Experimental result showed that 95% SO₂ removal efficiency is achieved for 0.1 M H₂O₂ as a reactant. Experimental results agreed excellently with the developed CFD model and can be used for designing industrial packed columns.
