Scrubber Design Calculation Excel Best __exclusive__ -
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):
For packed beds, pressure drop can be calculated using the Ergun equation or, more conveniently, by using manufacturer-provided pressure drop curves imported into a lookup table within the spreadsheet.

Essential for calculating gas density ( ρgrho sub g ) using the Ideal Gas Law. Liquid Solvent Properties Liquid Flow Rate (
In the world of air pollution control and chemical engineering, packed bed scrubbers are essential for removing gaseous pollutants (like HCl, NH₃, or SO₂) from industrial exhaust streams. While specialized simulation software (ASPEN, CFD) exists, —especially when done right. Here is a quick verification case to test
If absorption is concentrated (CO₂ in MEA, SO₂ in caustic), the NTU equation becomes implicit. Use with Enable Iterative Calculation (max iterations 1000, max change 0.0001).
Venturi scrubbers require more sophisticated calculations due to the complex physics of droplet formation and particle capture. However, Excel can handle these equations effectively. Essential for calculating gas density ( ρgrho sub
are designed specifically for controlling fine particulate matter. Gas velocities in the throat section can range from 60 to 200 m/s, which breaks the liquid into fine droplets that capture particles through inertial forces. They are particularly effective for particles smaller than one micron.
Always convert to actual gas flow using the ideal gas law before any diameter calculations. Include this conversion as a separate, clearly labeled step in your spreadsheet.
