Venturi Scrubber Design Calculation: Xls Upd

The volume of scrubbing liquid per volume of gas, typically ranging from 3 to 20 gallons per 1,000 ACF . Key Calculation Steps

Let's walk through a typical case: – 50,000 ACFM, 5 g/m³ inlet loading, target <50 mg/Nm³. venturi scrubber design calculation xls upd

Before sizing the scrubber, you must define the inlet conditions of the raw gas: Volumetric Flow Rate ( cap Q sub g Usually measured in Actual Cubic Feet per Minute (ACFM) or Operating Conditions: Temperature ( ), Pressure ( ), and moisture content (v/v). Gas Properties: Molecular weight ( cap M cap W ) and viscosity ( Humidification: Calculation of saturated gas flow rate ( cap Q sub s a t end-sub The volume of scrubbing liquid per volume of

These vary with temperature and pressure and affect the Reynolds number.
