(216a) A Principle of Corresponding States for Packed Column Pressure Drops

We have found that a principle of corresponding states exists for the pressure drop in packed columns. When pressure drop data are properly renormalized to conditions at flood a remarkable collapse of these data onto a single "master" curve occurs. We explain the reason for this collapse with an analogy to the principle of corresponding states found in classical thermodynamics. Data are also shown for several packings and packing families.
