A hidden killer. Even with 100 stages, if liquid doesn’t wet the packing, mass transfer fails.
): An empirical factor used in pressure drop and flooding calculations. 2. Step-by-Step Calculation Methodology
: Identify the total inlet gas flow rate ( ), operating temperature ( ), operating pressure ( ), and the initial concentration ( ) of the pollutant.
To build the "best" Excel design calculator, structure your workbook across four dedicated tabs. This maintains clarity, prevents formula corruption, and allows for seamless auditing. scrubber design calculation excel best
HTU: This represents the efficiency of the specific packing material used.
Ensure the total pressure drop does not exceed the static pressure capacity of your system's exhaust blower fan.
) is chosen as a safe percentage of flooding, usually between 60% and 80%: A hidden killer
) via the generalized flooding correlation, and the total packing height ( ) via mass transfer unit integration (
This article provides a definitive guide to performing , focusing on the spreadsheet logic, key equations, and why Excel is the industry’s secret weapon.
Moving from 1-inch to 2-inch packing lowers the packing factor ( Fpcap F sub p The required removal percentage
Inputs for inlet gas flow rate, temperature, pressure, and detailed pollutant concentration.
Incorporate logical verification parameters using conditional formatting to flag unsafe operational ranges.
y2=y1⋅(1−η)y sub 2 equals y sub 1 center dot open paren 1 minus eta close paren Determine the equilibrium concentration. Select an operating ratio, typically chosen as to ensure an adequate driving force for mass transfer. Step B: Column Diameter and Cross-Sectional Area
The column diameter must be wide enough to handle the rising gas velocity without causing "flooding"—a condition where the upward gas velocity prevents the downward flow of liquid, filling the column with liquid and causing a massive pressure spike.
The required removal percentage, often dictated by environmental regulations (e.g., 99.9%). Liquid Solvent Properties Liquid Flow Rate ( Qlcap Q sub l
