Internal parts of distillation column :- In this article I would like to discuss the internal part of the distillation column. How many types of internal part of distillation column who play the important role in the separation of two different type of fluid . I will cover all the small things who are part of the distillation column Chemical and/or thermal separation processes are frequently carried out in columns. However, in order for a column to function, there must be some interior parts since without all that “stuff” inside, it would just be a pipe.The main components of a distillation column are trays, and the interface created by the vapour bubbles produced by the up-flowing vapour and the down-flowing liquid allows for a mass transfer between the two phases. The bubbling region, the weir, and the downcomer are the several components that make up a tray.

The various components placed inside columns are what make the separation process easier.
The main internal parts of distillation column are,
- collector
- distributor
- packing or trays
- grid support
- downcomer
Mist eliminator – These are used to stop entrainment at the vapor outlet and are situated at the top of the column. Inert fabric or packing materials may be used.
Liquid distributor
This part distributes the incoming fluid uniformly across the cross-section of the column. The various properties of your liquid will determine the type (channel, tube, nozzle, etc.) that is employed.
Packing
Borosilicate glass structures are frequently employed in packing because of their ability to withstand extreme temperatures and corrosion. If the circumstances of your procedure call for a different choice, several materials are available. This is very important Internal parts of distillation column.
Support grid
Trays effectively support structured packing by preserving the majority of the cross-sectional area of the gas flow and reducing pressure loss. The structure packing is also held in place by support grids constructed of various corrosion-resistant materials.
Wall wiper (funnel, around packing)
A column of liquid has a propensity to desire to run down the inner wall. To increase column efficiency, a wall wiper works to divert liquid off the inner wall back into the packing.
Collectors and redistributor
Placed beneath the packing, collectors snag the depleted liquid and either remove it from the column or feed it back to the redistributor.
- Structured DURAPACK packing is utilized when a high level of separation efficiency is required.
Process goals are intensified through the use of structured packaging. The DURAPACK is made of corrugated glass plates that are alternately placed and have flow channels that are 45° incline. The glass plates are fused together so that the only component in touch with the process fluids is borosilicate glass.
Steam intake – Even steam distribution makes efficient use of the packing, lowering the column’s total height.
Vortex breaker and outlet collector
These components are at the bottom of the column and aid in reliable liquid drainage by 11. Vortex breaker and outlet collector – These components are at the bottom of the column and aid in reliable liquid drainage by preventing sluggish liquid from entering the steam inlet.
Tray
The main components of a distillation column are trays, and the interface created by the vapour bubbles produced by the up-flowing vapour and the down-flowing liquid allows for a mass transfer between the two phases.
The bubbling region, the weir, and the downcomer are the several components that make up a tray.
The bubbling region specifies the tray type and how it works. The downcomer permits the passage of the liquid towards the lower plate and propels the steam through the bubbling area, while the weir fixes the liquid height and pressure decrease.
Structural packing
Labbe’s proposed method of packing, called structured packing, is renowned for its effectiveness and low pressure drop. Compared to other distillation column internals, it enables columns to be smaller. A series of corrugated sheets in the shape of honeycombs make up this packaging.
Conclusion
In the distillation of liquid mixtures, a distillation column is a crucial component that is used to separate the mixture into its component parts, or fractions, depending on the variations in volatilities. Both small-scale laboratory distillations and large-scale industrial distillations employ fractionating columns.
