Scrubber Design Calculation Excel Best | FRESH ⇒ |

Set up: Your design velocity must equal 70% of flooding velocity.

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.).

For soluble gases (SO₂, HCl, NH₃):

Pro Excel trick: Use GOAL SEEK to iterate L/G until target outlet concentration is met.

Calculate density & viscosity based on temperature and composition (air/steam mixture).
Formula (air at 1 atm):
rho_gas (lb/ft³) = (1.325 * P_psia) / (T_degR)
Use Excel’s SLOPE/INTERCEPT for steam/air blends. scrubber design calculation excel best

This is where the pollutant is actually removed. The height depends on how easily the gas dissolves into the liquid.

Use =IF(Flood%>0.85, "WARNING: Close to flooding", "OK") Use conditional formatting to turn the cell red if pressure drop exceeds 1.5 inH2O/ft. Set up: Your design velocity must equal 70%
