Scrubber Design Calculation Excel Hot Access

For an industrial "hot" scrubber design calculation in Excel, you need to structure your spreadsheet to handle gas cooling (quenching) mass transfer simultaneously

This post walks you through building a packed bed wet scrubber calculator for hot gas streams (SO₂, HCl, or particulate removal with cooling).

Tab 2: Psychrometric Engine (The "Hot" Core)

Use VBA or iterative circular references to solve for wet-bulb temperature.
Include a lookup table for water vapor pressure (0-212°F).
Calculate outlet humidity (grains/lb dry air).

Calculate pressure drop (ΔP) across the scrubber
ΔP = (f x L x ρ) / (2 x g)

The 5 Critical Calculations for Hot Scrubber Design

Before building your Excel spreadsheet, you must understand the core engineering equations. A professional design consists of five interconnected modules.

Materials of Construction (MOC): Standard fiberglass (FRP) or plastics like PVC will melt. Your spreadsheet should flag temperatures and recommend High-Temperature FRP, Hastelloy, or a brick-lined quench section.
