), dry gas composition, and target pollutant removal efficiency (e.g., 99%). Liquid-to-gas ratio ( minimum target), inlet water temperature ( ∘Craised to the composed with power C ), and chemical reagent concentration (e.g., % scrubber design calculation excel hot

Often, a "quench" section is placed before the packing to reduce the gas temperature to adiabatic saturation before it enters the packed section. This protects the packing.

Note that as gas cools, its actual volume decreases significantly. Design your column diameter based on the volume at the average or outlet temperature to avoid over-sizing. 3. Column Diameter & Flooding =SCFM * ((Inlet_Temp_F + 460) / 520) * (14

The inlet section must withstand thermal shock. Metal alloys or specialized refractories are required before the gas reaches the quenched, lower-temperature zone where plastics (like FRP or PP) can be safely used.

When treating gases above 150°C (300°F), standard scrubbing mechanics change drastically due to immediate heat and mass transfer. Two primary phenomena dominate the inlet zone of a hot gas scrubber: Design your column diameter based on the volume

Always add a 15–20% safety margin to the calculated packing height to account for liquid maldistribution and potential fouling over time.

The following section details the specific formulas and logic flows to be implemented in the Excel spreadsheet.

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
