This is where Excel shines. For gas absorption (e.g., HCl in water), the method is standard.

Use Goal Seek on pressure drop vs. gas rate to avoid flooding.
A complete packed column scrubber design sheet should also include pressure drop calculations, which can be performed using the generalized pressure drop correlation. For dry packing, the outlet gas flow rate can be calculated based on packing height and system geometry.
