Jan 28, 2020 · The feed to a distillation column can be liquid or vapor, or both, depending on the temperature, pressure, and composition of the feed. To quantify the thermal condition of the feed, the parameter q is defined as the fraction of the feed that is liquid.. It follows that 1 — q is the fraction of feed that is vapor: If the feed is a saturated liquid at its bubble point, q = 1.
