Design a scrubber to remove 99% of HCl from 10,000 m³/hr of air at 30°C, using water. Packing: 2" ceramic Intalox.

Before diving into Excel, it's important to understand the different types of scrubbers and the specific calculations each requires. The choice of scrubber type depends heavily on the application—whether you're removing sub-micron particulates, acid gases, or large dust particles.

For situations where you need a professional-grade report or an "off-the-shelf" validated tool, paid options are an excellent investment:

Define the inlet gas flow rate (ACFM), temperature, pressure, and the concentration of the contaminant (e.g., cap S cap O sub 2 cap H cap C l , or dust). Step 2: Determine Liquid-to-Gas (L/G) Ratio:

Column diameter must be optimized to prevent liquid flooding while ensuring adequate gas-liquid contact. Sizing calculations rely on the Generalized Pressure Drop Correlation (GPDR).

Embed a hidden sheet with all conversions (scfm to acfm, °F to °R, psi to psf). Use =CONVERT(value, "from_unit", "to_unit") if you have Excel’s Analysis ToolPak.
