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.


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.


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".


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.

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.

Fractional distillation and the impact on the environment?

Fractional distillation it is separating mixtures via their boiling points. Fractional distillation is done by adding some sort of material into the column that the vapor travels before being cooled and condensed while. Since the fractional distillation means the separation of a mixture into different componenets.Suppose the raw material entering into the distillation column contains many fraction(for example,if a crude oil is entering,it contains gases,gasoline,kerosene etc). if a distillation is done for such a material.this will be the fractional distillation.Because in a distillation column you will separate different components present in the crude Check the related question below to know more.


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 effect of column temperature on resolution?

Different substances have different boiling points. Distillation is the chemical process created to take advantage of this property. Cooling one side, the top of the column and applying a heat source to the bottom ensures lighter or more volatile substances accumulated at the top end of the column, assuming there is a constant flow with relative constant composition feeding the Distillation column, and an accumulation of less volatile material in the bottom.


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.


What is the condensed gas taken from a distillation column called?

The distillate.


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.
