) for common packings (like 2" Pall Rings or structured packing) into a lookup table using VLOOKUP or XLOOKUP . 3. Step-by-Step Excel Formula Architecture
Every robust Excel scrubber sheet must be built on three fundamental engineering principles, each with specific formulas you will code into your spreadsheet:
In Excel, the Eckert or Sherwood flooding correlation can be approximated using curve-fitted polynomial equations to find the flooding coordinates on the Y-axis: scrubber design calculation excel hot
Verify that the calculated liquid flow rate falls within the packing manufacturer's recommended wetting range (typically
Total mass entering the system (Dry gas + Initial moisture + Recirculation liquid water) matches total mass exiting (Saturated gas + Evaporated vapor + Bleed liquid). ) for common packings (like 2" Pall Rings
The diameter of a vertical packed scrubber is determined by the gas velocity relative to the flooding point.
A scrubber is a critical air pollution control device used to remove pollutants and particulate matter from gas streams. Designing a scrubber requires careful consideration of various parameters, including gas flow rate, pollutant concentration, and scrubbing liquid properties. In this write-up, we will demonstrate how to perform scrubber design calculations using Excel. The diameter of a vertical packed scrubber is
For gas absorption, packed bed towers are standard. The cross-sectional area ( ) is determined based on the gas velocity ( Vgcap V sub g
: This is the most critical design parameter. For venturi scrubbers, typical ratios are 7–20 gallons per 1,000 cubic feet of gas.
: For common spray towers, a typical velocity is approximately Calculate Area ( ): Calculate Diameter ( ):
