4. Pressure Drop (ΔP)

The "Hot" headache: ΔP increases with temperature because gas viscosity rises. Use the Leva correlation: $$ΔP (mmH₂O/m) = C \times (G')^1.82 \times (μ_g)^0.2$$ Where $G'$ = gas mass velocity (kg/m²·s), $C$ = packing constant.

    ), you must build these safety checks into your Excel sheet:

  • Evaporative Water Requirement

    . As the hot gas hit the recirculating liquor, it would evaporate water instantly, cooling the gas but shrinking its volume and changing the density. The Inputs:
