Scrubber Design Calculation Excel Portable 〈iOS〉

The foundation of any calculation is your data entry stream. In your Excel "Inputs" tab, include: : Volumetric flow rate ( ACFMcap A cap C cap F cap M ), temperature ( ), and pressure (

To build your Excel calculator, first create an "Input" section for these critical parameters: Gas Stream Properties : Flow rate ( scrubber design calculation excel

The pressure drop across the packing determines your operational costs. Design Equations For Venturi Scrubbers The foundation of any calculation is your data entry stream

– Using Johnstone’s equation : [ \eta = 1 - \exp\left(-k \cdot \sqrt\frac\Delta P\mu_L \cdot \sigma \cdot C\right) ] Simplified form for Excel: =1-EXP(-0.15 * SQRT(B4/2.5) * (Particle_Diameter_in_microns^0.5)) If not, check unit consistency

Use gas flow = 5000 m³/h, L/G = 2 L/m³, target ΔP = 25 in H₂O → Your Excel should predict Vt ~ 75–85 m/s. If not, check unit consistency.

Calculate (liquid to gas mass flow ratio) L_over_G = (Q_l * ρ_l) / (Q_g * ρ_g)

Solve for (gas mass flux at flooding, kg/m²·s): Y = (G'_flood² * F_p * μ_l^0.1) / (ρ_g * (ρ_l - ρ_g) * g_c) → Rearrange in Excel using =SQRT(Y * ρ_g * (ρ_l - ρ_g) / (F_p * μ_l^0.1))
