The design process focuses on solving three primary engineering challenges:
Ensure the Excel sheet flags an alert if the inlet temperature exceeds the thermal limit of standard materials like FRP (Fiberglass Reinforced Plastic).
User inputs are marked in .
Designing an industrial gas scrubber requires precise thermodynamic and aerodynamic calculations. When dealing with hot gas streams—such as incinerator flue gas, kiln exhaust, or furnace emissions—the design complexity increases. Hot gases undergo significant volumetric contraction upon entering a scrubber due to rapid evaporative cooling.
Air density formulas linked to temperature, water properties, and gravitational constants. Tab 2: Packing Material Database

By integrating these advanced considerations, your Excel-based design process will not only be faster and more accurate, but also specifically tailored to the demanding, high-temperature applications where scrubbers are most critical.
