a section above the feed tray called rectifying section and a trays which are above the feed tray called rectifying trays.
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.
overflash acts as a reflux for the lowest tray from which side draw is made and the flash zone.It prevents heavier ends from reaching up the column.
sieve tray
For a binary set of components you calculate the feed tray using the McCabe Thiele method. For more complex systems you would need to use a process simulator and perform a sensitivity analysis to determine the optimum feed tray.
In order to locate the feed tray in distillation, you need to calculate the field tray by using MCcabe Thiele field method. For more complex systems you need to use process simulators and perform a sensitivity analysis to determine the optimum feed tray.
The rectifying section in a distillation column is where the lighter distillate is being enriched and the heavier components removed. This is in contrast to the stripping section where the lighter components are being "stripped" out of the bottom product and the heavier components consequently concentrated.
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.
distillation column
Weeping is when liquid flows downward through the holes in a distillation tray. Normally vapor rises up through the holes and contacts the liquid on the tray. If the vapor rate is too low the liquid may be able to drop to the next stage through the holes, resulting in less than optimal vapor/liquid contact (and therefore less than optimal separation). Condensed liquid from above trays is generally distributed onto a distillation tray via a weir.

Crude oil is separated by fractional distillation. The components of crude oil are separated by a process which is known as fractional distillation. Crude oil is made of different components whose sizes, weights and boiling temperatures are different from each other. When the crude oil is heated with high pressure steam at a high temperature, it boils and forms vapour. The vapour enters a fractional distillation column and settled in the trays of the column. The trays have holes in them which raise the contact time among the vapour and liquids. The vapour rises in the column and cools, the hotter substances settle at the bottom of the column and the cooler substances rise to the top of the column. The substances in the vapour condense and the fractions of liquid collect in the tray and pass to condensers and storage tanks.

The fractionation column is used to separate components of a liquid by distillation.
This is an installation used for separation by distillation.
