: Estimate the total pressure drop across the packing and internals using correlations like Norton’s or Hesketh (for Venturi scrubbers) to size the fan or blower.

You do not have to start from scratch. Several excellent resources are available: scrubber design calculation excel best

) and surface areas for rings, saddles, and structured grids.

: Clearly label every cell with its units (e.g., ) to avoid common conversion errors. : Estimate the total pressure drop across the

This is where Excel shines. For gas absorption (e.g., HCl in water), the method is standard.

is the most practical way to handle complex correlations for tower sizing, pressure drop, and efficiency. Key Design Parameters for Excel Calculation : Clearly label every cell with its units (e

The column diameter is determined by calculating the gas velocity at which the liquid flowing down the packing becomes entrained in the upward gas stream—a phenomenon known as . Professional designs typically operate at 60% to 80% of the flooding velocity . Step-by-Step Mathematical Sizing Step 1: Calculate the Flow Parameter (

To make your Excel tool robust, user-friendly, and audit-ready, structure the workbook using the following architectural guidelines:

This traditional graphical method can be adapted for Excel using curve-fitted polynomial equations to find the flooding point based on the Liquid-Gas Flow Factor ( Flgcap F l g

Why? Because Excel offers transparency, rapid iteration, and customizability that black-box software cannot match. When built correctly, an Excel-based scrubber design tool can be 95% as accurate as expensive simulators at 0% of the cost.
