feed plate location in distillation column
In a crude oil distillation unit the feedstock liquid mixture is introduced usually near the middle of the column to a tray known as the feed tray. The feed tray divides the column into a top (enriching, rectification) section and a bottom (stripping) section.

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:

A distillation column with a total condenser and a partial reboiler is separating ethanol and water at 1 kg cm pressure. Feed is 0.32 mole fraction ethanol and is at 30° C. Feed flow rate is 100 kmol/h. The distillate product is a saturated liquid, and the distillate is 80 mol% ethanol. The condenser removes 2,065,113 kcal/h.

Determining the number of stages required for the desired degree of separation and the location of the feed tray is merely the first steps in producing an overall distillation column design. Other things that need to be considered are tray spacings; column diameter; internal configurations; heating and cooling duties.
