Optimizing Air Pollution Control: A Guide to Scrubber Design Calculation in Excel

In the field of chemical and environmental engineering, the design of wet scrubbers is a critical task. While specialized simulation software exists, Microsoft Excel remains the industry standard for preliminary sizing, vendor verification, and detailed process calculations. Its transparency and flexibility make it the "best" platform for understanding the underlying physics of scrubber operation.

Column height (packing + disengagement + sump)
Pump head (ΔP + static head)
Estimated cost (optional: based on diameter and material)

Scrubber efficiency calculation: The scrubber's efficiency is calculated using the formula:

Multicomponent simultaneous diffusion (e.g., acetone + toluene + air).
Heat effects (adiabatic saturation requires numerical integration – doable in VBA, but painful).
Foaming systems (Excel can’t predict foam height).
Dust/scour (particle scrubbing requires Stokes number calculations better done in specialized tools).
