Scrubber Design Calculation Excel Hot Today

). If the liquid rate is too low, the packing dries out; if too high, it triggers immediate flooding. If you are currently building this model, let me know: What (e.g., HCl, NH3cap N cap H sub 3 SO2cap S cap O sub 2 , or generic dust) are you trying to remove?

Designing a scrubber for hot gases introduces unique thermodynamics. The gas must be cooled down to its adiabatic saturation temperature before efficient mass transfer or particulate collection can occur.

): Divide the heat duty by the latent heat of vaporization of water ( Tsatcap T sub s a t end-sub scrubber design calculation excel hot

Clients are sensitive to energy costs. The sheet must predict pressure drop across the packing.

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 Designing a scrubber for hot gases introduces unique

This is the heart of absorption design. You cannot just "guess" the packing height. The is calculated as:

Ln(ΔP) = a0 + a1*Ln(G) + a2*Ln(L) + a3*T + ... The sheet must predict pressure drop across the packing

Affects density and requires significant cooling.

: Map cells like B16 as Tower_Diameter and B22 as Packing_Height to keep formulas clean and readable.

Before building your Excel spreadsheet, you must understand the core engineering equations. A professional design consists of five interconnected modules.
