As the reflux minimizes and heat energy remains to same that time sudden increase in pressure drop takes place.
As the vapour flow is higher compared to liquid flow so liquid is unable to comes down through downcomer and flooding occurs......

In distillation towers what does 'flooding velocity' means?
Generally: The flooding velocity of the column is the velocity of the vapor rising through the column at which the liquid on each stage is suspended. The flow of vapor up through the column will not allow the liquid to fall down through the column causing the stages to "flood".
What is an enriching section in a distillation column?
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.
How do you design distillation column?
Assuming you have binary components the McCabe Thiele Method should be used. Otherwise a process simulator such as Aspen, Pro/II, and/or KGTower should be used.
What should you do if your kerosene flash is increasing in the column?
By flash, it is assumed you mean the amount flashed in the flash zone after entering a column. If the amount flashed is more than you desire, lower the feed temperature. If the feed is some amount of saturated liquid and vapor, you will want to increase the percentage of liquid fed to the column. This applies to a general distillation column with more flash than desired.If this is a crude oil atmospheric distillation column, and you are getting too much kerosene in a side draw, your cut point probably does not meet the required specification. In this case you will need to adjust your pumparound rates and/or increase the amount of reflux.
Define reflux ratio?
reflux ratio is the ratio of the quantity of distilled material returns to the column to quantity of distillate. One can operate the distillation column without calculating reflux ratio, but the main purpose of it is to improve the efficiency of the distillate.
How flooding in distillation column control?
flooding in disillation column is control: 1) to reduce total crude charge, 2)to decrease the transfer temperture, 3) increase the tower reflux, 4) increase the tower pressure.
If the rate of the distillation through a packed column is too rapidflooding occursWhat effect would flooding have on the distillation?
If the rate of the distillation through column is too rapid flooding occurs will effect on distillation rate causing low crude column flush zone vaporization that causes low internal reflux rate between GO and GO product and the light materials does not vaporize and it will effect on fractionation ability. Those effects on the specification of the distillation. So effective on crude temp. it will be dropping then crude hydraulic limitation occurred and making the problem worse. so in the top of column boiling film will cause,

What is the best fractionating column for ethanol distillation using lab glass?
distillation column
Why maintain distillation column and distillation drum pressure?

What is fractionation column used for?
The fractionation column is used to separate components of a liquid by distillation.
What is a fractionating column?
This is an installation used for separation by distillation.
What is the condensed gas taken from a distillation column called?
The distillate.
What is a batch distilation column?
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.
What is the name of the column used to separate crude oil into its various components?
Fractionating column. The process is fractional distillation
Does distillation reduce the ionic product of water?
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.
