In the McCabe-Thiele diagram, if the x-coordinate of the point of intersection of the q-line and the vapor-liquid equilibrium curve is greater than the x-coordinate of the feed point, then the quality of the feed is
- Asuper-heated vapor
- liquid below bubble point
- Csaturated vapor
- Dsaturated liquid
Explanation
For a subcooled liquid feed (q>1, liquid below its bubble point), the q-line has a steep positive slope (q/(q−1)>1) extending from (zF,zF) up and to the right, intersecting the equilibrium curve at an x-coordinate greater than zF.
