Gas absorption in a packed bed scrubber relies on passing a contaminated gas stream upward through a chemical packing material while a liquid solvent (often water or an alkaline/acidic solution) flows downward. The packing maximizes the surface area for contact between the gas and liquid phases.
Instead of manually typing packing factors, create a "Database" tab listing common packing types (e.g., 2" Pall Rings, 3" Saddles) and their associated Packing Factors ($F$), Surface Areas ($a$), and Void Fractions ($\epsilon$). scrubber design calculation excel hot
Assuming a superficial gas velocity of 2 m/s: Gas absorption in a packed bed scrubber relies
Create a dynamic named range that pulls T_out from your adiabatic solver. Your velocity (V = Q_actual / Cross-sectional area) must use the average of Q_inlet and Q_outlet for accurate pressure drop calculations. Assuming a superficial gas velocity of 2 m/s:
A scrubber is a crucial piece of equipment in various industrial processes, used to remove pollutants and contaminants from gas streams. Designing a scrubber requires careful consideration of several factors, including gas flow rate, pollutant concentration, and scrubbing liquid properties. In this story, we'll walk through a step-by-step guide on how to perform scrubber design calculations using Excel.
where v is the superficial gas velocity ( typically 1-3 m/s).
Ensure the enthalpy of the exiting wet gas matches the total enthalpy of the entering hot dry gas minus losses.
