As discussed earlier, the distillation column working principle involves the separation of mixture components with varying boiling point. This way, vapor from a boiling mixture will mainly comprise of the element with a lower boiling point. Once this vapor is cooled, it condenses and the liquid formed will contain more of the volatile component; thus the original mixture will be left with more of the less volatile component.
What is distillation column? It is a pressure vessel where the mixture is separated. It is used to make the whole separation process possible based on the components' volatility differences. A standard distillation apparatus is made up of three main parts which are, a pall ring for vapor to pass, a condenser where the vapor is cooled, returning it to a liquid form and a source of heat which is used to vaporize the original mixture.
Tray Specification www.hatltd.com DS-DT-01 Rev 3 AlphaTRAY® DESIGN SHEET OVERVIEW Conventional absorption, distillation or fractionating trays consist of vapour/liquid contacting decks or trays with segmented liquid downflow areas. Columns can contain any number of trays installed vertically above each other.
Ideally, the mixture element with the lowest boiling point will vaporize first and the temperature remains constant until all substances are entirely evaporated.
There are two types of distillation columns, and each model is designed to offer a different kind of separations. Every design has a different level of complexity. The main types are batch columns and continuous columns.

Batch columns – in this operation, there is the introduction of a batch-wise feed to the column. This means that the column will be charged with a batch as the distillation process takes place. Once the desired results are achieved, the next batch is introduced, and the, cycle continues.
Continuous column – in this case, the distillation process is carried out in a continuous feed. This means that once the process is started, there are no interruptions until all the mixture is separated unless a problem occurs with the columns or other surrounding units. The continuous columns are designed to handle even high throughputs and happen to be the most commonly used in commercial industries.
The continuous columns are further categorized based on;
The continuous columns are further categorized based on;
• The nature of the feed that needs to be processed
In this case, there is the multi-component column which separates feed that contains over twp components and the binary column which is meant for separating feed with only two elements.
• The number of contained streams
These are based on the number function streams where the products are meant to pass. There is the multiproduct column which comprises of more than two streams.
• The fee exit during separation
This category is based on the side in which the feed goes out after separation. There is the extractive distillation whereby the extra feed settles on the bottom product stream and the azeotropic distillation where the extra feed settles on the top product stream.

Now that you already understand about the distillation columns let's have a look at its components. The first things to note are the column internals, which is categorized into two as follows;
Tray column – this is a situation where the trays of different designs are crafted to hold up the liquid to offer better contact between the liquid and vapor, thus ensuring a better separation. There are different types of trays in distillation column and they include dual-flow tray, sieve tray, bubble cup, and valve tray.

Packed column – this is where the packings are used in place of trays to enhance contact between liquid and vapor. They include structured packing, tower packing and random packing.
