Scrubber Design Calculation Excel Best Today

The best Excel-based scrubber design calculation tools rely on established chemical engineering principles like the Treybal or Perry’s Chemical Engineers' Handbook methods to accurately size equipment and predict efficiency.

where η is the scrubber's efficiency, C_in is the inlet concentration of pollutants (kg/m³), and C_out is the outlet concentration of pollutants (kg/m³). scrubber design calculation excel best

7. Demister (Mist Eliminator) Sizing

Add 6–12 inches of knitted mesh or chevron vanes at the top. Calculate velocity: V_demister = K_d * SQRT((ρ_l-ρ_g)/ρ_g) where K_d is 0.2–0.35. Compute HTU and NTU

Tab 4: Height_Design

• Compute HTU and NTU.
• Iterate using Data Table to see effect of L/G on height.
• Add pressure drop per foot, then total ΔP.

Calculate the cross-sectional area by dividing the gas flow rate by the allowable "gas velocity" (typically ~500 feet per minute for many industrial designs). Step 4: Calculate Efficiency: Use the formula: Efficiency % Inlet Concentration Outlet Concentration Inlet Concentration

1. Unit Conversion Automation

The most common source of scrubber design errors is unit mismatch (e.g., mixing Standard Cubic Feet per Minute (SCFM) with Actual Cubic Feet per Minute (ACFM)).

• Multicomponent simultaneous diffusion (e.g., acetone + toluene + air).
• Heat effects (adiabatic saturation requires numerical integration – doable in VBA, but painful).
• Foaming systems (Excel can’t predict foam height).
• Dust/scour (particle scrubbing requires Stokes number calculations better done in specialized tools).
