Line up the equations sequentially matching the engineering steps outlined above:
Stop guessing the L/G ratio. Here is a step-by-step guide to building a hot (high-temperature) packed bed scrubber design sheet in Excel, including flooding velocity, pressure drop, and makeup water.
If you can tell me the (especially if it is acidic), gas flow rate , and inlet temperature , I can help you find specific packing factor tables or provide a pre-filled Excel template framework for your scrubber design calculation .
= MAX(Minimum_Wetting_Rate * Column_Area, Calculated_Chemical_L_G * Saturated_Volumetric_Flow) Use code with caution. 4. Key Risks in Hot Gas Scrubber Design
To satisfy the search intent, your spreadsheet should have the following tabs: scrubber design calculation excel hot
Scrubber Design Calculation Excel Sheet: A Guide for Hot Gas Applications
. High-temperature inlet gases require an initial saturation step to prevent damage to internal packing and to stabilize the absorption chemistry. Core Calculation Workflow
X=LG⋅ρgρlcap X equals the fraction with numerator cap L and denominator cap G end-fraction center dot the square root of the fraction with numerator rho sub g and denominator rho sub l end-fraction end-root Use a polynomial curve fit in Excel to calculate from the calculated flow parameter along the flooding line.
Use VLOOKUP to match packing materials to their respective Packing Factors ( Fpcap F sub p ) and surface areas ( 5. Tips for High-Temperature Scrubber Design Line up the equations sequentially matching the engineering
Industrial processes often generate hot waste gases containing hazardous pollutants, particulate matter, and acidic vapors. Designing a wet scrubber for these applications requires precise engineering to handle both chemical absorption and extreme thermal shifts.
Before entering formulas, gather the following input parameters: Volumetric flow rate ( Qgcap Q sub g
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.
Tower diameter holds operational gas velocity safely within the non-flooding window ( Depends on the packing type
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 a typical hot application (Inlet: 600°F, Outlet: 160°F): Factor = (620) / (1060) =
What is the of your hot gas stream? What specific pollutant (e.g., SO2cap S cap O sub 2 HClcap H cap C l , or particulate matter) are you trying to remove?
): Calculate the flow ratio to position your operating line safely away from the equilibrium curve.
Depends on the packing type, gas packing packing factors, and fluid properties. Total Packing Height ( ):
