Question

HETP is numerically equal to HTU only when the operating line:

• A. Lies below the equilibrium line
• B. Lies above the equilibrium line
• C. Is parallel to the equilibrium line
• D. Is far from the equilibrium line

Hint:

Analyze operating and equilibrium line orientations to predict performance in separation processes.

Answer 1

The Correct Option is C

HETP (Height Equivalent to a Theoretical Plate) and HTU (Height of a Transfer Unit) become equal when the operating line is parallel to the equilibrium line. This condition represents a situation where the driving force for mass transfer remains constant.
