The q-line defines the thermal condition of the feed in a binary distillation column, determining the intersection of rectifying and stripping operating lines on a McCabe-Thiele diagram. This calculation uses the feed composition and vapor fraction to compute the liquid fraction (q), slope, and intercept of the q-line.
