Scrubber Design Calculation Excel Hot Fixed 🔥 Tested

This article provides a deep dive into the rigorous calculations required for and how to structure an Excel workbook that moves beyond static equations to dynamic, iterative solvers.

Start your Excel sheet with an input section for the "hot" inlet conditions.

The energy balance required to determine the saturation conditions conforms to the following thermodynamic relationship:

Always convert gas flow from Normal/Standard to Actual at operating temp. scrubber design calculation excel hot

This is critical for "hot" applications. You must calculate the heat transfer between the hot gas and the cooler liquid. : Sensible heat + Latent heat of evaporation.

Calculated to size the system fan or blower accurately. 2. Step-by-Step Scrubber Design Calculations

The Excel sheet should be organized into distinct modules to handle the physics of the scrubber.

: If using packing, aim for a "flooding" percentage between . If it exceeds this, increase the diameter. 3. Calculating Scrubber Height

Standard scrubber design assumes isothermal conditions or negligible temperature drop. For streams (typically >150°F / 65°C up to 1800°F), the physics shift dramatically: This is critical for "hot" applications

): Specific to your packing material (e.g., Raschig rings, Pall rings).

: This is the most critical design parameter. For venturi scrubbers, typical ratios are 7–20 gallons per 1,000 cubic feet of gas.
