Standard scrubber design assumes isothermal conditions. But when your inlet gas is at 400°C (752°F) or higher, three critical physics problems emerge: scrubber design calculation excel hot

Before chemical scrubbing happens, hot gas must be "quenched" to its adiabatic saturation temperature. Double-check that your Packing Factor ( Fpcap F

Designing a wet scrubber for hot gas streams—such as incinerator exhaust, boiler flue gas, or thermal oxidizer discharges—presents unique thermodynamic challenges that standard design spreadsheets fail to capture. Evaporative Cooling and Water Makeup
