Scrubber Design Calculation using Excel: A Step-by-Step Guide
Next Step: [Download the Pro-Tier "Hot Gas Venturi Scrubber Calculator" Excel Template (VBA Enabled)] – Includes psychrometric loop, material selector, and 3D output chart.
- Based on scrubber diameter, gas flow rate, and liquid flow rate, calculate the scrubber height (H)
- H = ( scrubber volume / (π x (D/2)²))
4. Pressure Drop (ΔP)
The "Hot" headache: ΔP increases with temperature because gas viscosity rises.
Use the Leva correlation:
$$ΔP (mmH₂O/m) = C \times (G')^1.82 \times (μ_g)^0.2$$
Where $G'$ = gas mass velocity (kg/m²·s), $C$ = packing constant.
Pressure Drop Calculation
), you must build these safety checks into your Excel sheet:
- Evaporation loss + blowdown loss + drift loss.
Evaporative Water Requirement
. As the hot gas hit the recirculating liquor, it would evaporate water instantly, cooling the gas but shrinking its volume and changing the density. The Inputs:
