Represents the mass transfer efficiency of the chosen packing. It depends on the gas velocity and packing type. Lower HTU values mean more efficient packing.
Your Excel workbook should be divided into sequential tabs or calculation blocks to mirror the physical process. Step 1: Inlet Gas Properties & Quench Calculations
For hot gases, L/G ratios of 1.0 to 2.5 L/m³ are typical. Create a sensitivity table in Excel (Data > What-If Analysis > Data Table) showing: scrubber design calculation excel hot
A standard scrubber calculator fails here. You need a thermal scrubber design calculation Excel hot version that includes .
Height depends on the required efficiency for gas absorption (mass transfer) or particulate removal. Represents the mass transfer efficiency of the chosen
⚠️ : Always use the pre-formatted input cells (usually blue) for your data and leave the output cells (usually green or white) for the formulas, ensuring data integrity.
Ensure your pump sizing in Excel accounts for this total volume. ⚠️ Critical Checks for "Hot" Gas Scrubbers If your incoming gas is over 150∘C150 raised to the composed with power cap C ( 300∘F300 raised to the composed with power cap F Your Excel workbook should be divided into sequential
Rapid cooling saturates the exit gas with water vapor, creating a visible white moisture plume at the stack. The spreadsheet should calculate down-stream reheating requirements if local environmental regulations prohibit visible plumes. If you want to build this tool, let me know:
High evaporation may lead to entrainment. Ensure efficient mist eliminators are included. Conclusion
A more robust Excel formula using the : $$ \Delta P \approx \fracu_t^2 \rho_g A_t^0.1331270 \times \left( L/G \right) $$ (Note: Ensure consistent units: Pa or in. w.c.)
