Superheated steam is often used in a distillation column to provide efficient heat transfer for the separation process. The high temperature of the superheated steam helps to vaporize the liquid components being distilled while maintaining a consistent temperature throughout the column. This can improve the overall separation efficiency and allow for better control of the distillation process.

What is the meaning of super heat?
Superheated steam is steam at a temperature higher than water's boiling point
Why do you supply stripping steam in a distillation column when you are heating the crude to a temperature where fractions lighter than residuum go up?
Stripping steam aids in separation in the column by "stripping' lighter components to higher trays in the column. While the crude is heated to a temperature where the pure components would normally go up, in crude oil the lighter components are often entrained in the heavier ones and the separation is not ideal. In actual practice stripping steam rates affect the flash points of the products as well as the concentration of hydrogen sulfide (H2S) in the products. The stripping steam added to the bottom of the column also affects the amount of overflash in the flash zone.
Why steam distillation is preferred over the fractional distillation?
Steam distillation is preferred over fractional distillation in cases where the compounds are heat sensitive and may decompose at high temperatures. Steam distillation also allows for the separation of compounds that are immiscible or have different boiling points that are very close together. Additionally, steam distillation is often a more efficient and cost-effective method for isolating volatile compounds from natural products.
How many stages are there to steam distillation?
There are typically three stages to steam distillation: heating the mixture to generate steam, vaporization of the desired component, and condensation of the vapor to obtain the distillate.
What is fractionation column used for?
The fractionation column is used to separate components of a liquid by distillation.
In order for a high temperature boiler or steam engine to produce superheated steam?
In order for a high temperature boiler or steam engine to produce superheated water, or steam?
Which type of steam is imparted on the blades of turbine?
Superheated steam.
What happens when superheated steam pressure is reduced?
steam quality increase
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 much energy is used per kilogram of steam?
That would depend on if the steam is superheated dry steam or not and if superheated dry steam its temperature. It should be possible to google "boiler equations" or "boiler design" to get details.
Is steam superheated water?
No, steam is not superheated water. Steam is the gaseous form of water that is created when water is heated to its boiling point and vaporizes. Superheated water is water that has been heated beyond its boiling point and exists in a state where it is hotter than its boiling point.
Why maintain distillation column and distillation drum pressure?

Which is better wet steam or dry steam?
If by dry steam you mean superheated steam then dry steam because it has a higher calorific value
Is superheated steam suitable for air heaters instead of saturated steam?
No, superheated steam gives off little energy. Most of the heat given off by steam is the latent heat of condensation as it undergoes a phase change from vapor to liquid. Superheated steam could first be "desuperheated" by adding water until it reaches the saturation point, then used for heat transfer processes.
Why saturated steam is used in exchangers frequently rather then superheated?
The heat transfer coefficient of superheated steam is poor. Saturated steam has a better heat transfer coefficient, and also most of the heat transferred from steam occurs because of the condensation phase change.
Why is superheated steam used in power plant?
because if the steam is not superheated the remaining water droplets reduce efficiency and can cause corrosion and pitting. +++ Nearly! Saturated steam, as non-superheated steam is called, is really only steam at the pressure and temperature in the boiler. Once it starts to expand as a gas in doing its work, the pressure and temperature fall and condensation will set in, leaving less and less useful water-vapour to act as a gas. Hence, as you say, the efficiency falls.
What happen if you heat steam?
If you heat steam under pressure you get "superheated steam" under higher than original pressure
