Figure 2: Examples of q-line slopes The q-line (depicted in blue in Figure 1) starts at the x = y line and intersects the starting point of the rectifying section operating line. The parameter q is the mole fraction of liquid in the feed, and the slope of the q-line is q / (q - 1).

used for the distillation of subcooled liquid ( or superheated vapor) feed. There is also the q-1. (10). This is known as the equation of the feed line.

If feed is a subcooled liquid, q>1 (i.e., L' augmented by vapor condensation), "slope" of feed equation is positive. If feed is a superheated vapor, q<0 (i.e., L' decreased evaporation), "slope" of feed equation is positive.

For sub-cooled liquid, q > 1 and the slope of the feed line is positive but less than infinity. For super-heated vapor, q < 0 and the slope of the feed line is

If the feed is a vapor— liquid mixture, q is a fraction. Values of q greater than 1 indicate subcooled liquid feed. Values of q less than 0 indicate superheated vapor feed. Now let us look at the intersection points (x„ y,) of the stripping and rectifying operating lines. Use of equations (2.28) and (2.30) gives:

These limits are derived when the feed is either a superheated vapor or a subcooled liquid (when the enriching section operating line coincides \\·ith the diagonal line on the x -y diagram). 3. Some conceptual errors will appear in the deri,·at.ion of q-line.

Feed quality q: q < 0 is superheated vapor; q = 0 is dew point vapor; 0 < q < 1 is a liquid vapor mixture; q = 1 is bubble point liquid; q > 1 is a subcooled
