High inlet temperatures require specialized materials (e.g., alloy stees, specialized FRP, or refractory linings) before the quench zone. 2. Key Design Steps and Excel Formulas scrubber design calculation excel hot
Represents the difficulty of the separation. For dilute systems with a clean scrubbing liquid, it simplifies to:
) unique to your chosen packing material (e.g., Pall rings, Raschig rings, or structured packing), find the gas velocity at flooding ( Vfloodcap V sub f l o o d end-sub ). A standard safety convention is to design the column at . Where: | Parameter | Value | Formula |

The liquid-to-gas ratio (L/G) is a critical parameter in scrubber design. A higher L/G ratio typically results in better contaminant removal, but also increases the energy consumption.
