This is your data entry zone. Group your inputs clearly using distinct cell coloring for user-entered data versus calculated values. Inlet temperature ( ∘Craised to the composed with power C ), mass flow rate ( ), molecular weight, and pollutant concentration ( mg/m3mg/m cubed
For packed towers, you need to calculate how much packing height is required to absorb the target pollutant (e.g., SO2cap S cap O sub 2 HClcap H cap C l
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 scrubber design calculation excel hot
The water supply system possesses enough physical capacity to continuously deliver the calculated hourly evaporative makeup volume.
To make your Excel tool user-friendly, auditable, and robust, use the following structural blueprint: Tab 1: Input Summary (Data Entry) This is your data entry zone
The design of a scrubber for hot gases is an iterative process that begins with understanding the physical properties of the gas at its saturated state. 1. Calculate Adiabatic Saturation Temperature ( Tsatcap T sub s a t end-sub
| | | | --- | --- | | Ql (m³/s) | 0.01 | | Qg (m³/s) | 1 | | L/G | =0.01/1 | =0.01 | This evaporation adds water vapor to the gas
While the carrier gas volume shrinks, the total gas volume gains a massive amount of water vapor evaporated from the scrubbing liquid.
: A measure of the mass transfer efficiency of the packing material or spray.
Because hot gas calculations rely heavily on the vapor pressure of water at various temperatures, you can insert this standard VBA function into your Excel workbook to automate the process:
