To build the "best" Excel design calculator, structure your workbook across four dedicated tabs. This maintains clarity, prevents formula corruption, and allows for seamless auditing.
) depends on the difficulty of the separation process and the physical efficiency of the chosen packing material.

For gas absorption operations with dilute concentrations (less than 5% solute), the driving force is assumed to be linear. Excel can evaluate NTUGcap N cap T cap U sub cap G

Pressure drop is a critical design parameter affecting fan selection and operating cost. Packing type (e
where T g is inlet gas temperature in Kelvin and d p is particle diameter.
What is the (e.g., HCl, SOβ, or particulate matter)? What is your inlet gas flow rate ? Are you designing a packed bed or a venturi scrubber ?

Use XLOOKUP or INDEX/MATCH on the Dashboard tab to automatically pull the correct Fpcap F sub p based on the user's dropdown selection. 4. Advanced Excel Techniques for Scrubber Design
