Before building the spreadsheet, define these inputs:

), creating a high-energy zone where liquid injected into the throat is atomized into tiny droplets. These droplets collide with dust particles, capturing them.

Calculate Saturated Gas Properties (Gas is usually saturated at the throat). Calculate Throat Velocity and Throat Diameter ( Calculate Drop Size ( ) using the Nukiyama formula. Calculate Inertial Impaction Parameter ( Calculate Overall Pressure Drop ( ΔPcap delta cap P ΔPcap delta cap P in. W.C.in. W.C. Actual Efficiency ( Throat Dimensions (Length and Diameter). 4. Optimization Tips High Efficiency: Increase the throat velocity (

Essential for determining the throat area and overall scrubber sizing. Liquid-to-Gas Ratio ( Before building the spreadsheet, define these inputs: ),

When designing a calculation sheet in Excel, you are essentially solving for three main variables:

(\Delta P) in kPa, (L/G) in L/m³, (v_t) in m/s. Calculate Throat Velocity and Throat Diameter ( Calculate

[ \Delta P = 0.44 \times \left( \fracLG \right) \times v_t^2 ]
