Designing a for hot gas streams—such as flue gas from industrial combustion—requires balancing mass transfer with significant thermal changes. The following guide outlines the core design calculations, specifically tailored for an Excel-based implementation, focusing on the unique challenges of "hot" inlet gases. Core Scrubber Design Process
When a hot gas enters a wet scrubber, it is cooled by the evaporation of the scrubbing liquid. For engineering purposes, the gas is assumed to reach its . In Excel, you can solve for Tsatcap T sub s a t end-sub using the following energy balance:
Calculations must be performed on a to account for the additional water vapor added during cooling. 3. Sizing the Tower Diameter Individual Design of 2 Scrubbers - UKDiss.com scrubber design calculation excel hot
Hot gases occupy a larger volume than cooled gases. Once you have Tsatcap T sub s a t end-sub
The design of a scrubber for hot gases is an iterative process that begins with understanding the physical properties of the gas at its saturated state. 1. Calculate Adiabatic Saturation Temperature ( Tsatcap T sub s a t end-sub Designing a for hot gas streams—such as flue

, you must calculate the volumetric flow rate of the gas at this lower temperature to size the vessel correctly: For engineering purposes, the gas is assumed to reach its
: Initial and saturation humidity ratios (lb water/lb dry gas). Use the Excel Solver Add-in to find the Tsatcap T sub s a t end-sub that balances this equation, as Hsatcap H sub s a t end-sub are both temperature-dependent. 2. Determine Saturated Gas Flow Rate ( Qsatcap Q sub s a t end-sub
