Scrubber | Design Calculation Excel Hot __top__
Before sizing the tower, you must define the hot gas properties. Hot gas streams (such as boiler flue gas or kiln exhaust) are less dense and hold more moisture than ambient air. Step A: Calculate Actual Gas Density ( ρgrho sub g
Designing a scrubber—specifically for gas streams—requires accounting for gas cooling (humidification) before sizing the physical vessel. Most Excel-based guides follow a specific sequence to determine the required tower diameter and height based on mass transfer or particulate removal needs. 1. Pre-Design Step: Humidification (Hot Gas Adjustment)
An Excel spreadsheet allows you to quickly evaluate different packing materials, gas flow rates, and liquid-to-gas (L/G) ratios. Organize your workbook into four distinct, logical sections. Section 1: Input Parameters (Data Entry) scrubber design calculation excel hot
Before you trust your spreadsheet for a thermal scrubber specification, confirm these four items:
| Scrubber Type | Typical L/G Ratio | Application | |---|---|---| | Spray tower | 0.5–2.5 L/m³ | Particulate removal, simple gas absorption | | Packed bed | 0.3–1.5 L/m³ | Gas absorption (SO₂, HCl, NH₃) | | Venturi | 0.5–2.5 gal/1,000 ft³ (≈0.07–0.33 L/m³) | Fine particulate collection | | Cyclonic scrubber | 1–3 L/m³ | Combined particulate and gas removal | Before sizing the tower, you must define the
This equation demonstrates why — increased gas viscosity reduces the Stokes number, decreasing the probability of inertial impaction.

Scrubber design calculation in Excel is both an art and a science, requiring a deep understanding of fundamental engineering equations, a practical appreciation for spreadsheet modeling techniques, and careful consideration of the unique challenges posed by . With the availability of free and publicly accessible Excel spreadsheets, engineers can accelerate the design process, reduce computational errors, and optimize scrubber performance before committing to costly fabrication and installation.
