Scrubber Design Calculation Excel Best Info

Industrial air pollution control is a critical challenge, and wet scrubbers are among the most effective technologies for removing particulate matter and gaseous pollutants from exhaust streams. For process and chemical engineers, mastering scrubber design calculations is essential—and doing so efficiently in Microsoft Excel can transform a complex engineering task into a streamlined, repeatable process.

Your Excel sheet must start with a dedicated input module containing three categories of variables: Actual volumetric flow rate ( Qgcap Q sub g ), operating temperature ( ), operating pressure ( ), contaminant gas molecular weight, inlet concentration ( yiny sub i n end-sub ), and target outlet concentration ( youty sub o u t end-sub Liquid Stream Properties: Solvent density ( ρlrho sub l ), solvent viscosity ( μlmu sub l ), and initial contaminant concentration ( xinx sub i n end-sub

Determine the tower's cross-sectional area based on a target (e.g., 500 feet per minute for some plate towers) or by staying within a safe percentage of the flooding velocity (typically 50%–85%). Determining Scrubber Height : scrubber design calculation excel best

Flow rate (ACFM), Density, Temperature, Pressure, Component Concentration (e.g., SO₂ ppm), Humidity.

Before diving into the math, let’s validate the claim.

In seconds, Excel returns:

Goal: Minimize diameter while keeping pressure drop < 40 mmH2O/m.

To improve your calculator further, you can look into integrating for high-concentration gas streams, adding structured packing geometries to the database, or writing custom VBA macros for automatic liquid-rate optimization . Share public link Determining Scrubber Height : Flow rate (ACFM), Density,
