Here is a quick verification case to test your Excel formulas: User Inputs: Gas Density: Liquid Density: Target Removal Efficiency: Selected Packing Factor ( Fpcap F sub p ): Design Velocity: Set to based on a conservative fraction of flooding. Target Sheet Outputs: Cross-Sectional Area: Column Diameter: Required NTU: Bed Height (assuming conservative HTU of 2.5 ft):
The height of the packed bed depends on how easily the contaminant transfers from the gas to the liquid. This is calculated using the and the Height of a Transfer Unit (HTU) .
With the actual gas flow known, diameter is straightforward: scrubber design calculation excel best

): Apply your safety/derating factor (e.g., 60% of flooding) to find the design velocity ( With the actual gas flow known, diameter is
, this tool is the gold standard for estimating capital and annual operating costs based on waste gas composition and pollutant properties. Spray Tower Rating Spreadsheet : Developed by experts like Meloni Marco

Once your spreadsheet is verified against a known benchmark or textbook problem, lock all calculation cells ( Review > Protect Sheet ). Leave only the primary input cells editable to prevent accidental formula deletion.
Even with correct overall height and diameter, poor liquid distribution can render a scrubber ineffective.
