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.

What is a rectifying tray in a distillation column?
a section above the feed tray called rectifying section and a trays which are above the feed tray called rectifying trays.
How do you calulate the feed plate of a distillation column?
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.
Why need Over flash in distillation tower?
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.
In what situation would you use fractional distillation over simple distillation?
You would use simple distillation when the two products you are trying to separate have large difference in boiling points. Fractional distillation is needed when the two products have very close boiling points (like Hexane and toluene). In petroleum refining, the word "fractionation", not "fractional distillation" is used, often interchangeably with "distillation". When we have a crude mixture of different compounds which have very minor difference in their boiling points and cannot be separated simple distillation, then fractional distillation is used. Differenciation of components of petroleum is done by this process
Which type of tray used in Demethanizer column?
sieve tray

Why is weeping not good in a 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.
What do you feed Venus?
You feed them bugs but don't feed them any human food like Hamburgers and keep them in a bowl or tray of water
What has the author N M Abdul-Razzak written?
N. M. Abdul-Razzak has written: 'A study of tray distillation and point efficiency'
Do you feed a hamster once or twice?
You should have a small dish tray. Just put food on the dish tray and the hamster will eat when he/she feels like it.
What is coning in distillation?
Coning occurs due to low liquids flow velocities when compared to gas which results in pushing of the liquid away from the tray openings.
Can someone tell me where to locate the vacuum operated valve in a 2000 Chevy Blazer Thanks?
remove the battery and the battery tray. It is below the battery tray and is mounted to the inside front of the the wheel well.
What are the m240 machine gun condition codes?
Condition 1: the bolt is locked to the rear. The safety is on. The source of ammunition is in position on the feed tray. The cover is closed. Condition 2: not applicable condition 3: the bolt is forward. The chamber is empty. The safety is off. The source of ammunition is in position on the feed tray. The cover is closed. Condition 4: the bolt is forward. The chamber is empty. The safety is off. The feed tray is clear of ammunition. The cover is closed.
Why need Over flash in distillation tower?
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.
Why is the feed in a distillation column introduced from the bottom?
This is not a rule. it is depend upon the feed conditions. eg. feed at 1. saturated liquid (cold) 2. partial vapors 3. Vapours 4. saturated vapors 5 at boiling point
How many times a day do you have to feed 2 hamsters?
Usually hamsters eat by themselves. All you have to do is make sure you add food to its tray and is never empty. They also enjoy picking food on the tray.
