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
Because the gas is hot, a large portion of the scrubber water will evaporate. The Excel sheet must account for this in the material balance, or the packing will run dry. scrubber design calculation excel hot
Use formulas like Eckert's Pressure Drop method to calculate the pressure drop across the packing, which is essential for fan sizing. 4. Leveraging Excel's Advanced Tools
where:
Before building the spreadsheet, you must understand how hot gas behaves inside a wet scrubber. Evaporative Cooling and Quenching The Excel sheet must account for this in
You cannot calculate the final column diameter without knowing Tsatcap T sub s a t end-sub
M_gas * Cp_gas * (T_in - T_out) = M_evap * h_fg
When dealing with "hot" gas streams, the most critical calculation is often the . Failing to do this correctly will result in a severely undersized or oversized scrubber. Leveraging Excel's Advanced Tools where: Before building the
$$Q_actual = Q_std \times \fracT_op + 273273 \times \frac1.013P_op$$
In industrial processes ranging from chemical production to waste incineration, gas cleaning is critical. For high-temperature applications—often referred to as "hot" scrubbing—designing an efficient system is complex. It requires careful consideration of thermodynamics, gas-liquid equilibrium, and material science, all while aiming for high efficiency in pollutant removal.
Assuming a typical gas velocity of 3-5 m/s, let's use 4 m/s for this example.
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.
