To help me tailor this layout or provide specific equations, tell me: What are you designing (Packed Bed or Venturi)? What is the target pollutant you need to remove? If you have a specific engineering correlation you want written out into an Excel formula, let me know! Share public link
Customization: You can easily add "What-If" scenarios to see how the design reacts to a 20% increase in gas flow.
For venturi scrubbers, the online allows you to design systems using the Hesketh pressure drop equation and Johnstone collection efficiency correlations – a valuable reference for validating your own spreadsheet calculations. scrubber design calculation excel best

If you want an accessible "paper" (PDF guide) paired with a functional Excel tool, this is a community favorite.
Create a table with: | Packing Type | Material | Size (in) | Fp (ft²/ft³) | a (m²/m³) | ε (void fraction) | |--------------|----------|-----------|--------------|-----------|-------------------| | 1" Pall ring | PP | 1 | 56 | 207 | 0.92 | | 2" Intalox | Ceramic | 2 | 40 | 102 | 0.74 |
Every scrubber calculation sequence begins with raw process data. You must gather and verify these input values before starting your spreadsheet equations. Gas Stream Properties Volumetric Flow Rate ( Qgcap Q sub g
