Vd=Vf×Safety Factorcap V sub d equals cap V sub f cross Safety Factor Step D: Compute Cross-Sectional Area ( ) and Diameter (

Professional spreadsheets use a consistent color scheme: yellow cells for user inputs, blue or green for calculated results, and gray for fixed reference data. This approach, used in the Cheresources Packed Column Scrubber Design spreadsheet, makes your tool intuitive for other engineers to use.

HTU represents the mass transfer efficiency of the specific packing material used. It depends on gas and liquid physical properties, flow rates, and packing characteristics ( Cfcap C sub f 4. Total Packing Height The total height of the packing bed ( ) is the product of these two values: H=NTU×HTUcap H equals NTU cross HTU Step-by-Step Excel Sheet Architecture

For random packing (Leva’s method): ΔP (inWC/ft packing) = C1 * (L/G)^C2 * (Gas mass velocity)^C3 Store constants (C1, C2, C3) in a lookup table for different packing types (2" Pall rings, 1" Intalox, etc.). scrubber design calculation excel best

For packed scrubbers, the required packing height follows this relationship:

To tailor this calculation approach to your project, could you share the (e.g., HCl, NH3, SO2), the expected gas flow rate , and whether you plan to use random or structured packing ? Share public link

For packed beds, pressure drop can be calculated using the Ergun equation or, more conveniently, by using manufacturer-provided pressure drop curves imported into a lookup table within the spreadsheet. Vd=Vf×Safety Factorcap V sub d equals cap V

A logical sequence is: input worksheet, calculation worksheet, and presentation/output worksheet. This makes it easier for others to understand and audit your work.

To maximize the value of your Excel-based scrubber design tool, follow these best practices:

Good liquid distribution is critical for packed column performance. Your design must ensure adequate wetting of the packing material. It depends on gas and liquid physical properties,

) depends on the difficulty of the separation process and the physical efficiency of the chosen packing material.

Spray towers are the simplest type of wet scrubber, designed primarily for coarse dust particles larger than 10–15 µm, as well as for gas cooling and conditioning. Liquid consumption is relatively low, ranging from 0.5 to 8 liters per cubic meter of cleaned air.

This can be entered as a known value from vendor data or pilot tests. If unknown, use the Sherwood–Holloway correlation or similar for initial estimates.
