Scrubber Design Calculation Excel Hot Now

Liquid-to-Gas (L/G) ratio, Inlet Water Temperature (°C), Re-circulation rate.

Designing an industrial gas scrubber requires precise thermodynamic and aerodynamic calculations. When dealing with hot gas streams—such as incinerator flue gas, kiln exhaust, or furnace emissions—the design complexity increases. Hot gases undergo significant volumetric contraction upon entering a scrubber due to rapid evaporative cooling.

Spray towers are the simplest scrubber configuration. A liquid (typically water) is sprayed through nozzles into a vertical vessel as gas flows upward. The (available from melonimarco.it) performs preliminary calculations of removal efficiency and pressure losses for single‑stage spray towers. Internal scrubber parameters for spray towers include: scrubber design calculation excel hot

The "Hot" headache: ΔP increases with temperature because gas viscosity rises. Use the : $$ΔP (mmH₂O/m) = C \times (G')^1.82 \times (μ_g)^0.2$$ Where $G'$ = gas mass velocity (kg/m²·s), $C$ = packing constant.

Need a template? Look for downloadable workbooks that include VBA macros for iterative solving, as standard Excel formulas cannot handle the circular logic required for true hot gas adiabatic saturation.

This technical guide breaks down the essential engineering formulas required to build a robust, professional tailored specifically for hot gas streams. 1. Process Parameter Inputs

), 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., %

Engineers should consider:

Account for the high moisture content of quenched gas by sizing a chevron or mesh mist eliminator at the top of the tower to prevent liquid carryover.

For a desired efficiency η_target, the required throat velocity can be found by:

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.
