A scrubber is a type of air pollution control device that uses a liquid to remove contaminants and pollutants from a gas stream. The design of a scrubber involves several key calculations to ensure that it can effectively remove pollutants and meet emissions standards. In this write-up, we will discuss how to perform scrubber design calculations using Excel.
), you must build these safety checks into your Excel sheet:
By integrating these advanced considerations, your Excel-based design process will not only be faster and more accurate, but also specifically tailored to the demanding, high-temperature applications where scrubbers are most critical. scrubber design calculation excel hot
This is the heart of absorption design. You cannot just "guess" the packing height. The is calculated as:
| Scrubber Type | Key Excel Formulas / Features | | :--- | :--- | | | Hesketh Eqn for ΔP; Johnstone Eqn for η; Liquid Droplet Diameter correlation. | | Packed Tower | GPDC chart (or curve-fit) for ΔP; Material balance for Liquid/Gas (L/G) ratio. | | Spray Tower | Evaporative cooling / mass transfer for hot gas quenching; simple, direct L/G ratio. | A scrubber is a type of air pollution
If the hot gas is cooled by water evaporation, it will reach an adiabatic saturation temperature ( Tascap T sub a s end-sub
This section calculates the structural dimensions of the vertical packed tower. ), you must build these safety checks into
offers a downloadable spreadsheet for preliminary single-stage spray tower calculations, including removal efficiency and pressure losses.
Always convert gas flow from Normal/Standard to Actual at operating temp.
Here is a step-by-step procedure for performing scrubber design calculations in Excel:
Qgas, in+Qliquid, in=Qgas, out+Qliquid, out+Qevaporationcap Q sub gas, in end-sub plus cap Q sub liquid, in end-sub equals cap Q sub gas, out end-sub plus cap Q sub liquid, out end-sub plus cap Q sub evaporation end-sub
