The diameter of a vertical packed scrubber is determined by the gas velocity relative to the flooding point.
Before building your Excel spreadsheet, you must understand the core engineering equations. A professional design consists of five interconnected modules.
: This ratio (typically 0.1 to 10) determines the volume of scrubbing liquid needed to handle the pollutant load and provide necessary cooling. Pressure Drop ( cap delta cap P : Use correlations like Norton’s Darcy-Weisbach scrubber design calculation excel hot
Inlet Gas T (°C) → Outlet Gas T (°C) → Water Evap (L/s) → Outlet RH (%)
To prevent the liquid from being blown out of the top of the tower, you must calculate the flooding velocity. Packing Factor ( Fpcap F sub p The diameter of a vertical packed scrubber is
The diameter must ensure the scrubber operates below the flooding point. The often use the Generalized Pressure Drop Correlation (GPDC) . Calculate the flow parameter (

via heat balance, find the true design ACFM of the cooled gas:
Designing a scrubber for hot gases introduces a critical thermodynamic phase before chemical absorption even begins: . Quenching and Evaporation
A complete wet scrubber design evaluation follows a sequential engineering workflow:
