The scrubber height (H) can be calculated using the following formula:
Where:
Wet scrubber design requires precise calculations to ensure pollutant removal efficiency and operational safety. This guide breaks down the essential parameters for building a "hot" gas scrubber design spreadsheet in Excel, focusing on packed bed towers. Core Design Objectives scrubber design calculation excel hot
Before deploying your Excel design sheet for official project estimations, verify it against known standards using this final checklist:
The required height depends on the mass transfer efficiency needed to meet outlet concentration targets. The scrubber height (H) can be calculated using
The Excel file should be organized into the following tabs:
: This is the most critical design parameter. For venturi scrubbers, typical ratios are 7–20 gallons per 1,000 cubic feet of gas. The Excel file should be organized into the
By mastering these calculations, you move from guesswork to precision engineering—ensuring your hot gas scrubber operates safely, efficiently, and without thermal failure.
The first step is establishing the "source" data. In an Excel sheet, these are typically grouped in a dedicated "Inputs" tab. Gas Stream Properties : Include the inlet volumetric flow rate (e.g., in ), inlet temperature, and pressure. Saturation Calculations
