Scrubber Design Calculation Excel Hot

Account for massive water loss due to evaporation. Your Excel sheet must calculate: .

Column Diameter, Pressure Drop, Packing Height, Liquid Consumption, Outlet Gas Temperature.

), which must be safely below the column flooding limit (typically designed at of flooding velocity): scrubber design calculation excel hot

The efficiency is governed by the inertial impaction parameter ($\Psi$). Larger particles and higher relative velocities result in higher efficiency.

Many spreadsheets assume ideal gas behavior and a dry gas pressure drop using the Ergun equation. These are preliminary estimates. A real system will behave differently, especially with a liquid flowing through the packing. Account for massive water loss due to evaporation

) using a psychrometric chart or humidity ratios. The scrubber is sized based on this saturated outlet volume, not the hot inlet volume. Target Efficiency : Define the required collection efficiency (e.g., for particulates) based on regulatory standards. 2. Determine Column Diameter The column diameter ( ) is primarily a function of the gas velocity required to avoid flooding while maintaining contact time. Calculation

Designing a wet scrubber for high-temperature ("hot") gas streams requires balancing pollutant removal efficiency with heat recovery and structural integrity ), which must be safely below the column

): Calculate the energy needed to pull gas through the scrubber. = (Q_sat * Delta_P) / (3600 * Fan_Efficiency) (where Delta_P is in Pascals and Flow is in 4. Key Design Considerations for Your Sheet

When hot gas meets the scrubbing liquid, water evaporates instantly. This cools the gas down to its adiabatic saturation temperature.
