By embedding these thermodynamic balances and hydraulic constraints into an organized Excel sheet, process engineers can instantly run "what-if" scenarios for changing inlet temperatures, optimizing water consumption, and sizing vessels accurately. If you are currently building this model, let me know: scrubber design calculation excel hot
The hot gas transfers its sensible heat to the liquid, causing the liquid to evaporate. This evaporation adds water vapor to the gas stream, increasing its humidity while dropping its temperature. The lowest temperature to which the gas can be cooled by evaporating water into it is the ( Tascap T sub a s end-sub
“Gas Flow = 5000 m³/h | Velocity = 2 m/s → Scrubber Diameter ≈ 1.0 m, Packed Height ≈ 5.0 m, Liquid Flow ≈ 50 m³/h ✅ Designed for 90% SO₂ removal using water”
For a typical hot application (Inlet: 600°F, Outlet: 160°F): Factor = (620) / (1060) = t_r > 3 * t_e for safe operation
For designing and calculating wet scrubbers in Excel, there are several specialized templates and resources available that cover hydraulic design, mass transfer, and cost estimation. Spray Tower Scrubber Rating : Meloni Marco
When hot gas enters a wet scrubber, the liquid rapidly cools the gas via adiabatic evaporation. The gas temperature drops down to its wet-bulb temperature. Your Excel sheet must calculate this thermal equilibrium to account for significant water loss.
Developing a model allows engineers to optimize packed tower designs efficiently. By rigorously calculating gas velocity, packing pressure drop, and the thermal balance, you can ensure a reliable, efficient hot scrubber design. If you are looking to refine your model, If you are currently building this model, let
