The objective of this research was to study the absorption efficiency of Sulfur Dioxide and Hydrogen Sulfide in Packed Bed Scrubber. The experiments were performed in a bench-scale packed bed scrubber packed with 70 mm Tellerette plastic media up to height of 1.50 m and operated in countercurrent mode. The operating variables included gas concentrations, NaOH concentrations, gas velocity and liquid to gas ratio (L/G). The inlet concentrations of SO2 varied from 200-500 ppm and H2S varied from 50-200 ppm. The concentration of NaOH aqueous solutions were 0-0.025 molar. In addition, gas velocity varied from 0.707 – 1.627 m/min and L/G ratio varied from 5 – 13 l/m3. The sample ports were placed along the column at heights of 0, 0.30, 0.60, 0.90, 1.20 and 1.50 meters.The results showed that, the amount of sulfur dioxide and Hydrogen Sulfide absorbed could be improved with an increase in the concentration of sodium hydroxide solution, L/G ratio and decrease gas velocity. The optimum concentrations of sodium hydroxide solution were 0.01 molar for Sulfur Dioxide and 0.002 molar for Hydrogen Sulfide. Moreover, the contact times were 60 seconds for Sulfur Dioxide and 120 seconds Hydrogen Sulfide. The highest removal efficiency of Sulfur Dioxide and Hydrogen Sulfide in Packed Bed Scrubber were 98% and 100%, respectively.
