To get a highly accurate , you must account for thermal effects, evaporation, and gas expansion when handling hot gas streams .
Air density formulas linked to temperature, water properties, and gravitational constants. Tab 2: Packing Material Database scrubber design calculation excel hot
Pressure drop is a critical performance and economic parameter. For wet scrubbers, the overall pressure drop is the sum of: To get a highly accurate , you must
Always size your scrubber based on the saturated volumetric flow rate ( Qsatcap Q sub s a t end-sub For wet scrubbers, the overall pressure drop is

Column Diameter Sizing Determine the column diameter based on superficial gas velocity ). For most vertical scrubbers, is kept between to avoid flooding while maintaining contact time. Calculation: Mass Transfer & Packing Height Calculate the Height of a Transfer Unit (HTU) Height Equivalent to a Theoretical Plate (HETP) . For hot acid gases (like cap H cap C l
An advanced Excel workbook designed for hot gas scrubbing is not just a calculator; it is a robust engineering tool. Here is what you should look for when downloading a spreadsheet or building your own:
