Add a conditional format: If ΔP > 80 mmH₂O/m → (risk of flooding).

Pressure drop is a critical performance and economic parameter. For wet scrubbers, the overall pressure drop is the sum of:

This module determines the saturated gas flow rate. It utilizes iterative formulas or Excel’s feature to solve the heat balance equation: scrubber design calculation excel hot

Typical µ_ref values: Air at 20°C → 1.81×10⁻⁵ Pa·s.

Typically 300°F to 1000°F+ for industrial vents.

For , the Hesketh equation (EPA APTI‑413 reference) is commonly used: ṁevap=QsensibleΔHvapm dot sub e v a p end-sub

This article guides you through the step-by-step math, core chemical engineering principles, and Excel formulas needed to design a high-efficiency packed bed or venturi scrubber for hot gases. 1. Characterize the Hot Inlet Gas

: Essential for sizing the fan or blower motor; usually calculated for both irrigated and dry packing. assets-global.website-files.com Scrubber Design Excel Resources

The first step in packed bed tower design is establishing the tower diameter (

The pressure drop determines the fan power required for the system. In Excel, this is usually calculated using the or the Leva correlation for packed beds:

Always add a 15–20% safety margin to the calculated packing height to account for liquid maldistribution and potential fouling over time.
