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.
Weeping is caused due to low vapor velocity. As vapor velocity is not enough, vapors will not pass through tray holes, moreover vapors will pass through gap between tray and column. So, there will not be vapor liquid equilibrium on a tray.
distillation column
The distillate.
Flooding in a distillation column occurs when the vapor velocity becomes too high, causing liquid to accumulate in the column. This can lead to decreased separation efficiency, poor heat transfer, and reduced distillate purity. It can also cause excessive pressure drop, leading to operational issues and potential damage to the column internals.
The process is distillation based on vaporization.
The purpose of the pumparound is to cool and partially condense the upflowing vapors.
Limiting the hole area to 13-14% prevents weeping in distillation columns. This may be limited by the allowable pressure drop specified for the column (too little leads vendors to specify a higher % hole area, thus causing weeping).
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.

The fractionation column is used to separate components of a liquid by distillation.
This is an installation used for separation by distillation.
The distillate.
This is a distillation column that doesn't have a continuous feed. The material that is to be distilled will typically be in a round bottom still at the end of the column.
Fractionating column. The process is fractional distillation
i dont know if new improved distillation process have arrived but if you take the old plate distallition or packed column distillation process..then the answer to your question is NO.

it is boiled and ran into a distillation column
