Scrubber Design Calculation Excel Hot

: Calculated based on the gas mass flow rate and a target "percentage of flooding" (typically 50–85%) to avoid liquid backup. Height of Packing (HETP) : Determined using correlations like Norton’s to ensure enough contact time for chemical absorption. Pressure Drop ( cap delta cap P

A proper design calculation must start with these foundational inputs: Gas Characteristics : Volumetric flow rate ( cap Q sub g ), inlet temperature ( cap T sub i n end-sub ), moisture content, and pollutant concentration (e.g., cap H sub 2 cap S cap S cap O sub 2 , or particulate matter). Removal Requirements : Desired outlet concentration ( cap C sub o u t end-sub ) and overall absorption efficiency ( Saturation State : For hot gases, calculating the saturation temperature ( cap T sub s a t end-sub

Note that as gas cools, its actual volume decreases significantly. Design your column diameter based on the volume at the average or outlet temperature to avoid over-sizing. 3. Column Diameter & Flooding
