  11. Calculations – Absorber Sizing • Assumptions • 60% Flooding Velocity of 5 ft/s • 10 Stages • HETP = 3 ft • 4 ft for gas and liquid distributors • Height • H = (10 * 3 ft) + 4 ft • H = 34 ft

  12. Calculations – Absorber Sizing Continued • Diameter: • Radius = (VGasIn/(π*.6 *Vflood))1/2 • R = (101576.3 ft3/hr /(π*10800 ft/hr))1/2 • R = 1.73 ft • D = 2R = 3.46 ft
