Question

What is the concept of hetp in absorption?

Answer 1

Packed Height (Dilute): HETP. HETP (Height Equivalent to a Theoretical Plate) As we have noted, instead of a tray (plate) column, a packed column can be used for various unit operations such as continuous or batch distillation, or gas absorption.

Answer 2

HETP arises from the same concept of equilibrium stages as does the theoretical plate and is numerically equal to the absorption bed length divided by the number of theoretical plates in the absorption bed (and in practice is measured in this way).
